Howto:Understand console output

2010-05-10T04:45:00Z

Michaelfavor: fixed typo

This document lists '''[[FlightGear]] errors''', how to get rid of them and other '''console output'''. If FlightGear quits but does not give you any error, try increasing the [[FlightGear Launch Control#Debugging|Log Level]].

Errors can appear in various locations, but the most common one is the console (a black window), which pops up when you run fgfs.exe.

==Errors with known solutions==
===Airports/.... Done===
This is not an error. The message lets us know that [[TerraSync]] is updating the <tt>[[$FG_SCENERY]]/Airports</tt> directory.

===Base package check failed ... Found version [none] at: ...<br>Please upgrade to version:===
* FlightGear was unable to find the [[$FG_ROOT]] directory. Set it using the <tt>--fg-root=</tt> commandline option.
* When using [[CVS]] with binaries, the data must match the binary. You cannot use data from a different date than the binary's release date.

===condition: comparison without property[1] or value===
A condition (like <tt><less-than></tt> or <tt><equals></tt>) exists, without either:
* a property to check
* a value to check the property against

===Could not find at least one of the following objects for animation:===
This means that FlightGear is unable to find an object in a .ac file. Check the .xml file (where the animation is stored) to see if the object-names match those in the .ac file. If you are not the aircraft's author you can safely ignore such warnings.

===creating 3D noise texture... DONE===
Tells you that a new noise texture is created. It is not an error and can be ignored.

===Error: [Screen #0] GraphicsWindowWin32::setPixelFormat() - No matching pixel format found based on traits specified====
Try changing the [[FlightGear Launch Control#Page Four - Options and Run|BPP]] value of your FlightGear setup. If that does not work, your graphics card is probably not able to run FlightGear 1.9 and higher. Another graphics card, or an older FlightGear version will likely "fix" the problem.

===Error: bind() failed in make_server_socket()===
When using [[Howto: Multiplayer|multiplayer]] or socket input, this usually means you specified an invalid ip address or the port is in use. Note: for multiplayer, you don't need to use the ''--multiplay=in,...'' option at all, FlightGear (since version 1.0) figures out the proper setting automatically. Only use when you know what you are doing.

===Error: connect() failed in make_client_socket()<br>SG_IO_OUT socket creation failed===
Your computer is not connected with the internet.

===Error: RenderTexture requires the following unsupported OpenGL extensions...===
Your graphics card doesn't support some graphics feature that FG requires. Update your drivers, change the BPP value and/or try disabling some of the visual goodies like [[3D Clouds]].

===Failed to find .... in apt.dat.gz===
You need to edit ATC/default.tower and ATC/default.atis. You can open these files with any text editor. Either remove or fix the entries containing your airports ICAO code (like KSFO).

===Failed to open file ...===
Check if the file exists on your system. If the missing file is a scenery object; be sure you have the latest [http://scenemodels.flightgear.org/download/SharedModels.tgz Shared Models] from the [[FlightGear Scenery Database]].

===Fatal error: mismatched tag ...===
In some .xml file, an opening tag (like <tt><sim></tt>) does not match its closing tag (like <tt></sim></tt>). This error is hard to track down, best method is to comment (place code between <nowiki></nowiki>) most of the aircraft. Then uncomment code one by one, until the error appears again.

===Fatal error: name must begin with alpha or '_'===
This error comes up when a property should be formed of which the name does not start with a letter of the alphabet or _. If this error only happens with certain planes, contact their authors.

===Fatal error: unclosed token===
A token (<nowiki></nowiki>) has been started, but not closes. Add <nowiki>--></nowiki> at the correct line.

===FGMultiplayMgr::MP_ProcessData: No such file or directory===
This is telling you that there's someone online on the multiplayerserver, using a plane that you do not have installed on your own system. In order to remove the error (and see the other plane) you have to install the plane that the other pilot is using.

===FGMultiplayMgr - No receiver port, Multiplayermode disabled===
FlightGear [[Howto: Multiplayer|multiplayer]] has not been set.

===FGPropertyManager::GetNode() No node found for ...<br> In component: ... unknown property ... referenced. Aborting===
FlightGear found a reference in the [[FDM]] to a non-existing property.

===Found unexpected subsystem: system exiting. JSBSim failed to load aircraft and/or engine model===
You are probably trying to run an aircraft on a out-of-date version of FlightGear. The planes on the official download page are intended to be used with the latest version of FlightGear. Usage on any older systems may not work.

===freeglut (fgfs): Unable to create direct context rendering for window 'FlightGear'<br>This may hurt performance===
This reports that you do not have proper hardware accelerated 3D (direct rendering) configured.

===Gate ... doesn't seem to have routes associated with it===
A startup location in the [[Interactive Traffic#Ground networks|groundnetwork]] is not (properly) connected to a taxi route. Contact the airport author, or import the network to [[TaxiDraw]] and run the Verify network command to find the corrupted gate.

===glLinkProgram "" Failed===
Update your drivers; they have to support atleast OpenGL 2.0 for FlightGear 2.0 and later.

===loading scenario '...'===
This is not an error. It shows that an [[AI Systems#AI Models|AI scenario]] is loaded.

===Model not found: ...===
This one tells you that FlightGear was unable to find a certain file. The nice thing is that it also tells you excactly what file.

# Check if the file really does not exist at your computer.
# Try to locate the file in which the missing file is referenced. This is likely to be <tt>-set.xml</tt> in the root directory of the loaded [[aircraft]]. Between the <model> tags, the base model file is referenced. This file references to all other models that are displayed with the aircraft.
# Contact the aircraft author with a detailed bug-report, in which you state the excact location of the missing file and (if you found it) the file in which it is referenced.

===Nasal runtime error: nil used in numeric context===
This error is [[Nasal]] triggered by a Nasal file (the console should show what file (and line) and from where it was referenced). The Nasal script tried to do something with a [[Property Tree|property]] with an empty value. A solution is to fill the property before the Nasal is loaded. This can be done by setting the property in an [[aircraft]]'s <tt>-set.xml</tt> file or by adding a [[Nasal scripting language#Listeners and Signals|listener]] to the script.

[[Howto: Contact the developers|Contact the developers]] if this error is shown for a <tt>[[$FG_ROOT]]/Nasal/</tt> script.

===Near camera not rendering===
[[Image:Near_camera_off.png|500px]]

If you screen looks like the image above; make sure you have at least [[OSG]] version 2.7.6.

===No render bin name specified in render bin section===
Update [[SimGear]] (or binary) and your data directory.

===No render bin number specified in render bin section===
Update [[SimGear]] (or binary) and your data directory.

===OBJECT_SIGN: unsupported glyph `.'===
Check the OBJECT_SIGN lines in the .stg file of the tile that was loaded when this error showed up.

===OpenAL error <AL_INVALID_VALUE>: bind source <alGenSources><br>Failed to generate audio source.===
This error is probably displayed because of some misdirected audio settings in the [[aircraft]]s setup. Check the -sound.xml file of the aircraft and see if all files refered to really exist. If not, try to contact the author of the plane, so he can fix the problem in the [[FlightGear CVS|CVS]] version or solve the problem yourself and let someone commit the patch.

===OpenAL error (AL_INVALID_VALUE): constructor (alBufferData)<br>Fatal error: Failed to buffer data.===
Disabling sound is a temporarily solution for this problem.

===osgDB ac3d reader: could not find texture...===
See [[#Failed to open file ...|Failed to open file ...]]

===osgDB ac3d reader: detected surface with less than 3 vertices!===
In one of the loaded models a non-existing surface is found. This can be a single line (sometimes used to simulate thin wires) or a fault in the model.

===Program's vertex attrib binding ..., usrAttr...===
Tells you that an effect binded certain attributes to a [[Shaders|shader]].

===Scaling image...===
This means a texture, whether in the scenery on your aircraft or anyone elses (when multiplayer is enabled), is not sized to powers of two. All textures in FlightGear have to be sized to power of two (eg. 16*16, 32*64, 32*1024). As of version 1.9 textures are resized automaticly, but it does slow your computer down, so it's better to resize the noted textures.

===ssgInit called without a valid OpenGL context===
In short, your GL libraries are broken. So far only Red Hat 7.x users have experienced this (see http://www.redhat.com/bugzilla/show_bug.cgi?id=18867). The only solutions are possibly complicated ones: you can either change distributions (most of us prefer Debian) or upgrade/downgrade your Mesa libs.

===The system cannot find the file specified===
If you are running Windows Vista; start by looking in <tt>C:\Users\Owner\AppData\Local\VirtualStore</tt> and seeing if you have a folder called FlightGear in there. If you do, cut-and-paste (merge) that one with <tt>C:\Program Files\Flightgear</tt> and try to launch FlightGear again.

'''Hint:''' you may need to go under Tools and Folder Options to specify "Show Hidden/System Files and Folders" in order for AppData to be visible.

===Time zone reading failed===
This is probably caused by a line-ending problem in the timezone files. Win32 users can resolve the problem by downloading a DOS to UNIX conversion utility available at http://www.nottingham.ac.uk/~eazdluf/d2u.zip. Run as `d2u *.tab` from within the timezone directory to fix your timezone files

===Traffic manager could not find airport===
There is either an airport missing from apt.dat, or there is a wrong ICAO code in a [[Interactive Traffic#Building Traffic Files|traffic file]]. An airport missing from apt.dat could be due to a recent opening.

===Unable to choose requested pixel format===
Error should be solved as of version 1.9. If not, try changing your [[FlightGear Launch Control#Page Four - Options and Run|BPP]] and/or resolution.

===Unable to open aircraft directory===
The [[aircraft]] that you are trying to run most likely relies on another aircraft, which you did not install (yet). The error shows what aircraft, so go download that one!
=== Unexpected tag '...' found in YASim aircraft description===
FlightGear found a non-existing tag in the [[FDM]] of the aircraft you are trying to launch. If you have not changed the original aircraft, contact the aircraft author. Else, check the FDM througly for mistakes.

===Unknown exception to the main loop. Aborting... <br>Possible cause: No such file or directory===
This error could have a variety of sources, among them missing files but also other things. Increasing the [[FlightGear_Launch_Control#Debugging|log level]] to debug and repeating excactly what you did when the error came up, might provide some more information on what FlightGear was doing when the error occurred.
* Setting your [[FlightGear Launch Control#Page Four - Options and Run|BPP]] to a lower value might work.
* Changing the resolution to a smaller one might work as well.

===WARNING: Couldn't convert texture...===
You are trying to run an aircraft not compatible with your FlightGear version. Most of the time, this error appears when you fly an aircraft, textured with .png files on versions older than 1.9. Convert the textures manually to .rgb or upgrade your FlightGear version.

===Warning: Picked up TriangleIntersect===
Reduce your [[FlightGear Launch Control#Debugging|Log Level]] to alert. Or [[Showstoppers|send the fgfs output to /dev/null (unix systems) or 2>nul (Windows)]]. The errors might still be shown, but do not affect the sim anymore.

===Warning: TangentSpaceGenerator: unknown primitive mode 9===
This is an [[OSG]] error, showing up when an effect needs tangent vectors, but polygons are not support. The error itself can be ignored, altough some [[shaders]] may look wrong. Shader developers should try to minimise the use of polygons and use triangles and quads instead.

===YASim SOLUTION FAILURE:<br>Zero length fuselage===
There is a problem in the [[FDM]]. A fuselage section with similar ax and ay was created. Change the ax and/or ay values to match the aircraft.

==Errors without known solutions==
Please take a look at the upcoming errors and see if you know a solution to get rid of them. Your additions are grealy appreciated!

===AL Error (sound manager): Invalid Value at buffer add data<br>No such buffer!===

===Failed to execute command nasal===

===Failed to tie property ... to object methods===
A JSBSim error.

===FGMultiplayMgr::MP_ProcessData - message from ... has invalid length!===

'''Bugs''' should be reported at [http://code.google.com/p/flightgear-bugs/ this tracker].

The bugs at this page might be out-dated and thus already solved.

== Known Bugs ==
This section contains known and recorded bugs. It makes no claim to be a complete list, or even to be particularly accurate. For some good recommendations about making proper bug reports, you might want to check out [http://www.chiark.greenend.org.uk/~sgtatham/bugs.html].

'''Please note:''' There is a bug tracker on SourceForge at [http://sourceforge.net/tracker/?group_id=583]. ''Please note that the bug tracker is rarely (as far as can it can be determined) used (or even read) by the developers.

==== Incorrect altimetry. ====

There is evidently at least one serious misconception in the
code that calculates atmospheric pressure, altimeter settings,
et cetera. This can be easily demonstrated:

Park at or near the threshold of runway 33 at Aspen (KASE).
Under standard conditions, observe that the altimeter reads
7820 feet MSL, as it should.

Use the Weather : Weather Conditions dialog popup to
look at the ground-level altimeter setting (QNH).
This is bottom row in the "Alt (inHg)" column of the popup.
Verify that it is 29.92.

Now use the dialog box to change this property. Change it
to 30.92, a one-inch difference.

Go to your altimeter instrument and enter the new altimeter
setting in the Kollsman window. Ideally, this '''should'''
cause the instrument to read the correct altitude once
again, namely 7820 feet MSL.

However, due to bugs, it is likely that you will observe
something closer to 8120. This means the airplane is 300
feet lower than the altimeter says it is.

In case it wasn't obvious, when flying around near Aspen,
being 300 feet lower than you think you are can be very
bad for your health.

The absolutely correct formulas for computing the altimeter
setting are derived and explained on the [http://www.av8n.com/physics/altimetry.htm jsd altimetry page].

A patch to fix the altimeter has been offered.

==== Altimetry misnomers and misconceptions. ====

Both the Weather Conditions popup and the atis.cxx code
rely on the "pressure-sea-level-inhg" property and use
it in ways that the altimeter setting should be used.

For some people this may be merely a misnomer, but for
others it is clearly a misconception, as recent events
have shown.

The fact is, the altimeter setting is '''not''' the same
thing as the pressure at sea level (Psl), especially when
the airmass has a non-standard temperature profile.
The altimeter setting is something
else; it is properly called the altimeter setting. It
is also properly called the QNH, although private pilots
who fly only in the US may be unfamiliar with the QNH
terminology.

In the Remarks section of a METAR, you can sometimes
find the ''Reduced'' Sea Level Pressure, which is
unfortunately denoted SLP. This METAR SLP serves
the same function as the altimeter setting. Despite
its name, the METAR SLP is not equal to the honest-to-goodness
pressure at honest-to-goodness sea level (Psl), as
discussed in more detail on
[http://www.av8n.com/physics/altimetry.htm jsd altimetry page].

There needs to be a facility whereby routines that need
the altimeter setting can obtain the altimeter setting.

Correct altimetry formulas may be found on the [http://www.av8n.com/physics/altimetry.htm jsd altimetry page].

Existing code sometimes treads the "pressure-sea-level-inhg"
property as if it were Psl, and sometimes as if it were
METAR SLP. All this needs to be vetted.

==== Newton's laws violated by environment.cxx ====

Consider the following results of an experiment using fgfs:

alt: 662 mM: 0.0288 P: 99000.8462 T: 286.8563 rho: 1.1975
alt: 3462 mM: 0.0288 P: 89341.6721 T: 281.3920 rho: 1.1009

alt: 662 mM: 0.0289 P: 99000.8422 T: 256.9910 rho: 1.3404
alt: 3462 mM: 0.0289 P: 89341.6740 T: 252.0956 rho: 1.2333

The first pair of lines represent before and after a simple
flight from one airport to another, with a net gain in altitude of
2800 feet, under standard conditions. So far so good.

The second pair of lines represent exactly the same flight,
except that the ambient temperature was 30 degrees colder
than before. You can see that the density (rho) is greater,
in accordance with the ideal gas law.

The problem is that the delta_P is exactly the same for the two
flights. This is a problem because P is connected to the weight
of the air column. If the air is 12% denser, the laws of physics
require it to have a 12% steeper pressure gradient dP/dh ... but
alas this is not observed.

This incorrect pressure profile P(h) has many consequences affecting
engine performance, airfoil performance, altimetry, et cetera.

==== Z-buffer burn-through. ====

Sometimes distant objects can be seen through nearer objects that
are not supposed to be transparent. For example: Runway lights
sometimes burn through a solid cloud layer. Also runway lights
sometimes burn through aircraft structure. Some instruments
burn through the yoke.

It seems that so-called "2D" objects in the
background are likely to burn through "3D" objects in the
foreground. This is particularly noticeable in aircraft
that have a mixture of 2D and 3D instruments.

The ''position'' in space of the offending objects is OK, as
you can verify by shifting your PoV to get a little bit of
a side view. The obvious hypothesis is that the Z-order
is being mishandled in a Z-buffer somewhere.

==== Memory leak. ====

The simulator will gobble up about 3 gigabytes
of virtual memory overnight, while paused.
Without the
leak, the memory footprint would be less than 300 meg. The
difference between 300 meg and 3 gig is quite
significant on machines that have only 1 or 2 gig
of main memory.

A rather steady leak of 2 meg per minute is observed
during pause, no matter whether the aircraft is aloft
or parked on the ground. '''Vastly less leakage''' (two
orders of magnitude less, possibly zero) is observed
when the simulator is not paused, and the aircraft
is simply sitting on the ground with the parking
brake set.

This bug has been observed in multiple versions of fgfs,
including one compiled back in May, 2006 as well as
the most current CVS version.

This is 100% reproducible with a
ATI RV350 [Mobility Radeon 9600 M10] chipset
and the ati-fglrx driver.
The leak is observed whether or not
OSG_GL_EXTENSION_DISABLE=ATI:GL_SGIS_generate_mipmap is set.

==== Numerous bugs in ATIS feature. ====

1) The ATIS is supposed to change whenever there is a
significant change in the weather. The comments mention
this, but the code makes no attempt to implement this.

2) The code assumes that ATIS is prepared on the hour.
In practice this is virtually never the case; a new
ATIS is prepared hourly, but not on the hour. Also
this assumption is inconsistent with ATIS changes
based on the weather.

3) The code attempts to issue a station identifier, but
none is heard.

4) Multiple departures from standard phraseology.

5) The volume is too low; ATIS is not readable over engine noise.
This defeats much of the purpose of ATIS. The volume does
not respond to the /instrumentation/comm[N]/volume property.

6) When using the --enable-real-weather-fetch option, the weather conditions used for the ATIS message are the conditions at aircraft current position and not the conditions at the airfield. The METAR used at the aircraft's current position could come from a different airport.

x) Et cetera.

A patch to fix a few dozen ATIS bugs is available, but has not been
incorporated into FG CVS.

==== Problems with --altitude option. ====

When the aircraft is initialzed aloft using the
command-line --altitude=6000
option, 0.9.10 is observed to put up a blank screen
(no scenery, no panel) and to spew on the console
page after page like this:

Warning: invalid line segment passed to IntersectVisitor::addLineSegment(..)
nan nan nan 2.7093e+06 4.27332e+06 -3.87316e+06 segment ignored..
altitude = -1.69132e-41
sea level radius = -6.54575e-42
latitude = 6.9874e-316
longitude = 6.79737e-313
OpenAL error (AL_INVALID_VALUE): set_pitch
OpenAL error (AL_INVALID_VALUE): set_volume

==== Multiple bugs in the location-in-air popup. ====

The location-in-air popup turns off the magnetos and extends
the landing gear. Some pilots and flight instructors
deem this to be undesirable behavior, especially if all
they are trying to do is relocate from one airborne position to
another.

Similarly, it strongly perturbs the throttle setting,
aileron trim, elevator trim, rudder trim,
view angles, PoV position, and who-knows-what else.
Again, people who know about airplanes consider this to
be undesirable behavior.

There is also a tendency to place the aircraft into
dangerous unusual attitudes, and other bugs too numerous
to mention.

Evidently, though, there is at least one person who likes
things the way they are. Code that would have fixed these
bugs was rejected. Neither specific nor constructive criticism
of the code was offered. For details see the flightgear-devel
mailing list archives.

==== Nearest fix. ====

Did you know that there are 8 different BRAVO intersections
in the database?

Until now there was no support in the code for this; all but
one of the entries was thrown away at the lowest level. There
is a comment in the code saying that fixing this is on the
TODO list.

As for navaids (as opposed to waypoints), the low-level code
already provides support for ambiguous IDs, but the information
is not being used very wisely by the higher layers.

Code to fix these problems was offered to the community.
So far it has been completely ignored.

==== HSI instrument failure. ====

If you use the "heading indicator" checkbox on the
"instrument failure" popup to command a failure,
it has no effect on the HSI instrument used by
many aircraft in the simulator fleet.

This is because of wrong code in hsi.xml.

Backend code to handle this correctly exists, but has
apparently never been used. It needs one small fix,
followed by recompilation. A patchset to take care
of all this was offered to the community, but has
not been incorporated.

==== Flux gate not really a flux gate. ====

In the Instrumentation director, there are three heading-related
.cxx files.
* heading_indicator.cxx : vacuum driven, with drift
* heading_indicator_dg.cxx : electrically driven, with drift
* heading_indicator_fg.cxx : electrically driven, no drift

The "fg" in "heading_indicator_fg" is documented to stand for
"flux gate", as if the heading were slaved to a flux-gate
compass ... but the code does not implement any such thing.
All it really does is initialize the indicated heading to
the correct magnetic heading value, and then implement a
no-drift policy. This is incorrect behavior, as can be
seen by flying to an area where the magnetic variation is
different from what it was at the start of the flight. A
true slaved heading indicator would gradually accommodate
the new magvar.

The correct behavior ought to be easy to implement.

==== Weird noises during initialization. ====

It is observed that sometimes while the simulator is starting
up, before things are fully operational, weird noises are
produced. For example, in the c182rg, gear-in-transit
noises are produced for several seconds before the first
display becomes visible. (According to a dump of the
relevant variables, there is no evidence that the gear is
actually in transit, and no reason why it should be.)

Code to fix this was submitted. So far it has been
ignored.

==== Weird displays during fullscreen initialization. ====

If the --enable-fullscreen command-line option is used,
the window is enlarged to full-screen size at a time
when initialization is only half-complete. From this
time until the end of initialization, the display
contains weird combinations of leftover graphic objects
and other junk.

This is observed no matter whether the splash-screen feature
is enabled or disabled.

==== Fullscreen window sometimes misplaced. ====

About 20% of the time, when the --enable-fullscreen command-line
option is used, it opens a window of the correct size, but
badly misplaced relative to the screen, such that only one half
or one quarter of the window is on-screen.

==== Navigation databases out-of-date ====

The database of navigation waypoints and fixes has an internal
date of early 2005. It is missing quite a few useful fixes.
The FAA has defined quite a few new approaches in recent years,
and has revised others.

An updated version, based on a pull of the much more
current x-plane database, was made available. So far
it has been ignored.

Similar remarks apply to the ''navaids'' database.

==== Ident from phantom DME. ====

In the real world, some VOR stations and even some localizers
have a colocated DME station ... but there are plenty that
don't.

The DME has its own Morse ident, with a distinctive higher pitch.

In the simulator, due to a bug in the code, all stations
transmit the DME Morse ident ... even stations where no
DME is present.

The code in navradio.cxx finds the nearest VOR or LOC on the
frequency, and checks to see if it is in range. It also asks
for the "nearest" DME on the frequency, but makes no attempt
to check that it is in range. To say the same thing the
other way, there is no attempt to check that the aircraft is
within the service volume of the DME. Since there is almost always
a DME /somewhere/ on the frequency, the has_dme variable will
always be set true.

For a demonstration of this bug, park at KAOO airport and
tune up the AOO VOR (which has no DME). Or park at almost
any airport and tune up the localizer (since relatively few
localizers have DME).

==== Airport lighting in poor weather. ====

In real life, there are many circumstances where airport lights,
including approach lights, are turned on during the day. At tower airports, the lights are turned on during conditions of low visibility and/or low ceiling, and also turned on if requested by the pilot. For details, see [[http://www.faa.gov/ATPUBS/ATC/ATC.pdf FAA Order 7110.65p]].

The code to turn lights on and off is in simgear/scene/tgdb/obj.cxx. (Formerly it was in tileentry.cxx)
* All along, runway and taxiway lights have been on during the hours of darkness, as determined from the angle of the sun.
* As of version 0.9.10, runway lights and taxiway lights are turned on automatically if visibility less than 5000 meters, day or night. Apparently this is based on flight visibility, not on surface visibility (which would be more appropriate). Consequently, as you descend through a haze layer into improving visibility you can watch as the lights turn themselves off (which is not appropriate). Also: apparently the code treats a subset of approach lights as part of the runway lights, so that subset comes on also. The remaining approach lights appear to be permanently off.
* There is still no code to turn on the lights depending on ceiling.

At non-towered airports, the lights are usually pilot-controlled,
via radio, no matter what the weather. Presently the code treats them the same as towered airports. (Arguably this should be considered a wish-list item rather than a bug. [[User:Alfozavr|Alfozavr]])

It is important to get the lighting right, because it affects both the
legality and the practicality of performing instrument approaches
in marginal conditions.

==== Holes in the ground. ====

<del>Ever since the first win32-build of FG-OSG, there are at least two huge
ground scenery holes (missing scenery tiles) in the the Rhine/Main/Neckar-region in Germany.
The first one gapes at
the place which was formerly known as the city of Mannheim (near the
airport EDFM, which is still there), the second one has swallowed up a
big piece of Frankfurt am Main (near EDDF) and surrounding land.

First posted to the flightgear-devel list in November, 2006.</del>

This problem has disappeared in the latest FlightGear CVS version as of 2007-07-31, using OSG 2.0.

==== Mixture versus Altitude. ====

It is observed in the default c172p and in the c182 that at
high altitude airports (e.g. KGCN or KASE), to obtain max
static RPM, it suffices to move the mixture control only a
few mm aft of the full-forward (full-rich) position.

This is unrealistic. In a real aircraft under such conditions,
it would be necessary to pull the mixture control back about
an inch to obtain max RPM.

It's hard to say whether the carburetor is underreacting to the
altitude, or overreacting to the mixture control.

==== EGT reads high. ====

It is observed in the default c172p and in the c182 that the
EGT reads toward the high end of the scale under all conditions,
including idle. This is unrealistic.

Also, the EGT reads ''off-scale'' high under high-power conditions.

==== Flags missing from instruments. ====

Some of the standard instruments lack status flags. For example,
the GS needle goes to mid-scale if there is no valid signal. That'll kill you for sure. Reportedly the hi-res instruments implement flags, but the lo-res ones don't. Many aircraft are using the lo-res instruments.

Either the aircraft should be upgraded to use instruments that
display flags, or the instruments should be upgraded to be
display flags.

==== Problems with --model-hz option. ====

Specifying the --model-hz=10 command-line option results in the
following mess:

and so forth.

* Is this really that unexpected? 10 Hz is a extremely low update frequency for the FDM. The normal rate is 120 Hz.

==== CPU hogging. ====

The fsgs program will happily eat up >98% of the cpu cycles,
even when the simulator is paused. That seems excessive,
particularly during pause. This is on a 2GHz machine
with hardware acceleration. As a point of reference,
glxgears uses only a fraction of one percent of the cpu.

* This is an effect of the render-as-fast-as-you-can approach taken by FlightGear. Presumably the user still wants to be able to interact with the graphics when the simulator is paused. Activating sync to VBLANK might give the desired result if the cpu is fast enough to have time over between the frames. (Since most of the work in glxgear is done by the GPU it can much easier saturate the GPU with little CPU effort than FlightGear can.)

==== Glideslope service volume. ====

The code in navradio.cxx appears to assume the glideslope
service volume is the same as the localizer service
volume. This is quite unrealistic.

==== Extended service volume. ====

In some parts of the world, a goodly fraction of the
localizers have an expanded service volume (ESV),
often quite a bit larger than the standard service
volume you see in the AIM. The code in navradio.cxx
was ignoring the service volume information in the
database and wrongly assuming the default values
applied everywhere. Code to fix the range-related
part of the problem has been offered
but not yet incorporated.

==== Other service volume issues. ====

The code in navradio.cxx has no understanding of how
'''azimuth''' affects the
localizer. There is more to the story than reception range.
It is perfectly possible to be outside the LOC service volume
for reasons having to do with azimuth, not range.

Good ident will be heard, but false localizer courses will
cause serious trouble for the unwary pilot.

A patch to fix this (along with the ESV issue) has been
offered, but ignored.

There are also azimuthal issues with the /glideslope/
service volume. This has not yet been patched.

==== Menu buttons having a get-together. ====

This concerns "radio buttons" on menus, such as on the
location-in-air popup and elsewhere. By definition, it should be
impossible to have more than one radio button pushed down at a time.
However, illegal situations of this sort can be created
using a click-and-drag gesture. Aim at
a radio button, hold the mouse-button down, and drag ...
as if you wanted to drag the radio button to a new location.
This allows you to set a radio button without the others
being unset. If you persist, you can have every one of
the buttons in the pushed-down state at the same time.

Before you say, "well, don't do that then" or "garbage in,
garbage out", let me point out that it is possible for
a pilot to inadvertently make a tiny dragging gesture
when intending only a click. Also, when the desired
button is in the pushed-down state, it is easy to not
notice that other buttons are in the undesired state.

==== Altimeter setting unreadable. ====

The standard altimeter (used by the default c172p aircraft
and many others) had been using an unhappy hodgepodge of
layers. The analog Kollsman window was unusable, because
it was unlabeled, and the digital altimeter setting was
unusable, especially at altitudes near 2500 feet, partly
from being behind the needle. On a real altimeter, things
are positioned so that cannot happen.

Fixing this requires using a more suitable font, moving
the digits over, and getting rid of conflicting extraneous
markings.

A patch to implement this fix has been offered.

==== Memory mismanagement in subsystem_mgr. ====

It is bad luck to apply "delete" to an object that was not
created with "new" ... as in line 219 of subsystem_mgr.cxx

A patch is available, but has not been incorporated.

==== Yet more memory mismanagement. ====

When FG is trying to exit, it is very likely to abort
with a message such as

*** glibc detected *** double free or corruption (!prev): 0x0ad08b88 ***

There are at least three different instances of this bug,
each producing a different traceback. Here is one such
traceback:

<code>

== Missing Features and Traps for the Unwary ==

==== Version number, please. ====

<del>It would be helpful to have an easy, documented way to ascertain the
version number. A --version option on the command line would be
nice.</del> (this is now available in HEAD) Maybe also a help::about menu item, for use while fgfs is
already running.

One could imagine that info about key libraries would also be helpful. (also see [[Backwards Compatibility Initiative]])

==== Rabbits extinct. ====

In the real world, many airports have '''sequenced flashers'''
(aka the rabbit) as part of the approach-light system.

In the FlightGear world, the sequenced flashers are inoperative
everywhere. Grepping through the code suggests that no attempt
has been made to implement this.

==== No comm volume control. ====

In many aircraft including the default c172p, the comm
radios have no volume control knob. In other aircraft
including the pa24-250, there is such a knob, but it
apparently isn't clickable and apparently doesn't do
anything.

In contrast, the SenecaII exemplifies the ''desired'' behavior:
the knob rotates when clicked and
correctly controls the /instrumentation/comm[N]/volume
property. (This alas has no effect on the volume of ATIS
audio, but that must be considered an ATIS bug not a
Seneca bug.)

==== Incomplete Scenery. ====

Installing scenery from the [http://scenemodels.flightgear.org/ Scenery Objects Database ] without installing the shared models, will get you messages such as the following:

Failed to open file .../data/Models/fgfsdb/localizer.xml
Failed to open file .../data/Models/fgfsdb/WaterWorks30m.xml
Failed to open file .../data/Models/fgfsdb/GenericStorageTank5m.xml
Failed to open file .../data/Models/fgfsdb/GenericStorageTank10m.xml
Failed to open file .../data/Models/fgfsdb/GenericStorageTank20m.xml
Failed to open file .../data/Models/fgfsdb/GenericStorageTank30m.xml

You might get only a few such messages, or you might get
screenful after screenful.

So, make sure you download all scenery files that are needed for fgfs.

This obviously counts as a trap for the unwary.

- This is patently not a bug and should be moved to a "tips" section or similar. The need to download the shared models is clearly stated (in big, bold, capitals no less) on the respective [http://scenemodels.flightgear.org/download/ download page] in a central position...

==== ASOS and AWOS are AWOL. ====

At many non-tower airports (and even some tower airports) there
is automatic weather reporting of some kind.

It ought to be straightforward to implement this, as a slight
variation on the existing ATIS feature.

==== Roundoff problems with textranslate step and scroll. ====

The textranslate animation is delightful for 3D animation
of mechanical drum-type displays as on old-fashioned
odometers and Hobbs meters.

It is not, however, a convenient way to implement digital
readouts. It works OK for integers, but the code in
apply_mod() suffers from roundoff errors when dealing with decimal fractions, such as the ".1" in 122.1 MHz, particularly when the scroll-value is zero.
* One workaround is to stick to integers, e.g. integer kHz
rather than fractional MHz.
* Another workaround is to employ a small positive scroll value, step*1e-6 should suffice.
* A final option (with CVS) is to use the bias tag to let the code know how to
handle round-off. Use a bias value of 1/2 your smallest step value, and
use the same bias value on all digits.

What we really need is a whole new support routine for dealing
with 3D digital displays, something at least as nice as the
support for 2D instruments.

==== Broken start-up banner. ====

On start-up, the simulator prints Author: Unknown and prints a bogus Date.

The printout comes from JSBSim and refers to the (lack of) author, date and version fields in the JSBSim flight model XML file for the aircraft. According to the schema for JSBSim-ML (the markup language specification for JSBSim aircraft) the author, creation date, version, and description are not required fields, so the message that is printed out should account for missing elements.

BTG file format

2010-02-08T03:57:53Z

Michaelfavor: /* Geometry Objects */ correction

Terrain in [[FlightGear]] is currently stored using the Binary Terrain Format, in <code>*.btg</code> or <code>*.btg.gz</code> files.
These files contain geometry in the form of points, individual triangles, triangle strips and triangle fans.

The authoritative source for the format definition is the class <code>[http://www.simgear.org/doxygen/classSGBinObject.html SGBinObject]</code>, which is defined in <code>simgear/io/sg_binobj.{[http://www.simgear.org/doxygen/sg__binobj_8hxx-source.html hxx],[http://www.simgear.org/doxygen/sg__binobj_8cxx-source.html cxx]}</code>.

== General Structure ==

Each BTG-File contains a header followed by a variable number of objects.
Each object is introduced by a header indicating the type of object, the number of associated properties and the number of elements contained in the object.

=== Coordinates ===

All coordinates in the file (except for texture coordinates) are [[Geographic_Coordinate_Systems#Cartesian Geocentric Coordinates|cartesian geocentric coordinates]].

In order to allow more compact storage, all coordinates are stored as single precision floating point values relative to the center of a bounding sphere, except for the bounding sphere itself, which is stored in double precision format.

All measurements are in meters.

=== Texture Coordinates ===

Texture coordinates are used to map textures onto 3D faces.
For this each corner vertex of a face is associated with the location of the texture pixel to be shown at this corner.
The texture is then projected onto the face using interpolation between the corner vertices.

The x- and y-parts of the coordinates are specified in the range 0.0 to 1.0, where the location <code>(0,0)</code> relates to the origin of the texture and an x- respectively y-part of 1.0 corresponds to vertices at full width respectively height of the texture.

Texture coordinates exceeding the range 0.0 to 1.0 are wrapped around, so that repeating textures are possible.
For example if the x-parts of the texture coordinates of a face cover the range -2.0 to 3.0, the texture repeats five times horizontally.
[[TerraGear]] makes heavy use of this feature for larger areas of the same material.

=== Endianness ===

The files are stored in Little Endian, i.e. the least-significant byte is stored first.

=== Alignment ===

Some of the structures used in this file format are not properly aligned, i.e. not all fields start at an offset which is a multiple of their size.
Therefore special care is to be taken when translating these definitions into record types, e.g. C or C++ <code>struct</code>, as the compiler must be instructed not to enforce proper alignment.

== Header ==

{| border="1"
|-
! Byte offset
! Type
! Description
|-
| align="right"| 0
| unsigned short
| Version (currently 7)
|-
| align="right"| 2
| unsigned short
| Magic Number 0x5347 ("SG")
|-
| align="right"| 4
| unsigned int
| Creation Time (seconds since the epoch)
|-
| align="right"| 8
| unsigned short
| Number of Toplevel Objects
|}

In files before version 7, the number of toplevel objects was interpreted as a signed short, leading to a maximum number of 32767 objects in a single file.

== Objects ==

Each object starts by an object header.

{| border="1"
|-
! Byte offset
! Type
! Description
|-
| align="right"| 0
| char
| Object Type (see below)
|-
| align="right"| 1
| unsigned short
| Number of Object Properties
|-
| align="right"| 3
| unsigned short
| Number of Object Element
|}

The object type can be one of the following:

{| border="1"
|-
! Code
! Object Type
|-
| align="right" | 0
| Bounding Sphere
|-
| align="right" | 1
| Vertex List
|-
| align="right" | 2
| Normal List
|-
| align="right" | 3
| Texture Coordinates List
|-
| align="right" | 4
| Color List
|-
| align="right" | 9
| Points
|-
| align="right" | 10
| Individual Triangles
|-
| align="right" | 11
| Triangle Strips
|-
| align="right" | 12
| Triangle Fans
|}

The object header is followed by a list of properties.
The number of properties in this list is given by the '''Number of Object Properties''' field.

{| border="1"
|-
! Byte offset
! Type
! Description
|-
| align="right"| 0
| char
| Property Type (see below)
|-
| align="right"| 1
| unsigned int
| Number of Bytes in Property Data
|-
| align="right"| 5
| bytes
| Property Data
|}

The property type can be one of the following (see the object type descriptions for more details):

{| border="1"
|-
! Code
! Property Type
|-
| align="right" | 0
| Material
|-
| align="right" | 1
| Index Types
|}

Similarily, each element starts with a single unsigned integer, giving the number of bytes the element's data occupies.

=== Bounding Sphere Object ===

The Bounding Sphere object gives the bounding sphere of the tile, defined by a center and a radius.

The properties of a Bounding Sphere are ignored.

The elements of the Bounding Sphere object are bounding spheres.
Even though more than one bounding sphere may be stored in such an object, all except for the last one found in the file are ignored.

{| border="1"
|-
! Byte offset
! Type
! Description
|-
| align="right"| 0
| unsigned int
| number of bytes in this element
|-
| align="right"| 4
| double
| x-part of the center
|-
| align="right"| 12
| double
| y-part of the center
|-
| align="right"| 20
| double
| z-part of the center
|-
| align="right"| 28
| float
| radius of the bounding sphere
|}

Note that the element may be longer than 32 bytes, but only the first 32 bytes are actually used.

=== Vertex List ===

The Vertex List object contains a list of vertices to be referenced by other geometry primitives.

The properties of a Vertex List object are ignored.

Each element of a Vertex List object is a list of vertices.
Each of the vertices gets a unique index, starting with 0 for the first vertex found in the file and incrementing by 1 for each further vertex.

{| border="1"
|-
! Byte offset
! Type
! Description
|-
| align="right"| 0
| unsigned int
| number of bytes in this element
|-
| align="right"| 4
| vertices
| vertex list
|}

Each vertex is a triple of single precision floating point values:

{| border="1"
|-
! Byte offset
! Type
! Description
|-
| align="right"| 0
| float
| x-part of the vertex coordinate
|-
| align="right"| 4
| float
| y-part of the vertex coordinate
|-
| align="right"| 8
| float
| z-part of the vertex coordinate
|}

The number of vertices in an element is therefore the number of bytes in the element divided by 12.

=== Normal List ===

The Normal List contains a list of normals to be referenced by other geometry primitives.

The properties of a Normal List object are ignored.

Each element of a Normal List object is a list of normals.
Each of the normals gets a unique index, starting with 0 for the first normal found in the file and incrementing by 1 for each further normal.

{| border="1"
|-
! Byte offset
! Type
! Description
|-
| align="right"| 0
| unsigned int
| number of bytes in this element
|-
| align="right"| 4
| normals
| normal list
|}

Each normal is a triple of signed bytes, interpreted as fixed point values:

{| border="1"
|-
! Byte offset
! Type
! Description
|-
| align="right"| 0
| byte
| x-part of the normal coordinates
|-
| align="right"| 1
| byte
| y-part of the normal coordinates
|-
| align="right"| 2
| byte
| z-part of the normal coordinates
|}

The individual parts are interpreted by dividing each of the parts by 127.5 and subtracting 1.0, leading to a linear mapping from the range of 0...255 to the range of -1.0...1.0.

=== Texture Coordinates List ===

The Texture Coordinates List object contains a list of texture coordinates to be referenced by other geometry primitives.

The properties of a Teture Coordinates List object are ignored.

Each element of a Texture Coordinates List object is a list of texture coordinates.
Each of the coordinates gets a unique index, starting with 0 for the first coordinate found in the file and incrementing by 1 for each further coordinate.

{| border="1"
|-
! Byte offset
! Type
! Description
|-
| align="right"| 0
| unsigned int
| number of bytes in this element
|-
| align="right"| 4
| texture coordinates
| texture coordinate list
|}

Each texture coordinate is a pair of single precision floating point values:

{| border="1"
|-
! Byte offset
! Type
! Description
|-
| align="right"| 0
| float
| x-part of the texture coordinate
|-
| align="right"| 4
| float
| y-part of the texture coordinate
|}

The number of coordinates in an element is therefore the number of bytes in the element divided by 8.

=== Color List ===

The Color List object contains a list of color definitions to be referenced by other geometry primitives.

The properties of a Color List object are ignored.

Each element of a Color List object is a list of color definitions.
Each of the colors gets a unique index, starting with 0 for the first color found in the file and incrementing by 1 for each further color.

{| border="1"
|-
! Byte offset
! Type
! Description
|-
| align="right"| 0
| unsigned int
| number of bytes in this element
|-
| align="right"| 4
| color definitions
| color definition list
|}

Each color definition is a 4-tuple of single precision floating point values:

{| border="1"
|-
! Byte offset
! Type
! Description
|-
| align="right"| 0
| float
| red part
|-
| align="right"| 4
| float
| green part
|-
| align="right"| 8
| float
| blue part
|-
| align="right"| 12
| float
| alpha part
|}

The number of coordinates in an element is therefore the number of bytes in the element divided by 16.

=== Geometry Objects ===

All geometry objects are structured the same way, with each element consisting of a list of index-tuples referencing vertex, normal, color and texture coordinate lists.

Each geometry object may have a '''Material''' and an '''Index Types''' property.

The material is a string (not null-terminated) indicating the name of the material.
There are some special types of materials reserved to indicate that the geometry represents lights instead of solid structure.

The '''Index Types''' property is a single byte containing bit field indicating the lists referenced by each entry in the tuple-list.
The meaning of the bits is given in the following table:

{| border="1"
|-
! Bit Number
! Description
|-
| align="right"| (least significant) 0
| Each entry has a vertex index
|-
| align="right"| 1
| Each entry has a normal index
|-
| align="right"| 2
| Each entry has a color index
|-
| align="right"| 3
| Each entry has a texture coordinate index
|}

If no '''Index Types''' property is given, the tuples contain a vertex and a texture coordinate index.
The only exception is the Point object type, which only has vertex indices by default.

Each element of the object is a list of tuples, containing one or more unsigned short integers in the following order:

# Vertex Index,
# Normal Index,
# Color Index, and
# Texture Coordinate Index.

Only those fields indicated by the '''Index Types''' property are included in the file.
For example, if the '''Index Types''' property indicates that each entry has only a vertex index and a normal index, each entry consists of 4 bytes, the first 2 bytes containing the vertex index and the second 2 bytes containing the normal index.

The indices reference the respective lists, i.e. the vertex index references the vertex list.

We assume that the individual elements are numbered sequentially, starting with index 0 for the first element.

==== Points ====

In case of the Points object type, each of the elements represents a single point, e.g. a point lightsource.

==== Individual Triangles ====

In case of the Triangle object type, three succeeding elements are combined to form the vertices of a single triangle.
The vertices of triangle <code>i</code> (starting with 0 for the first triangle) are given by elements <code>3*i</code>, <code>3*i+1</code> and <code>3*i+2</code>.
To represent <code>n</code> triangles the list must therefore contain <code>3*n</code> elements.

==== Triangle Strips ====

The Triangle Strips object type also represents triangles, but in a more compact form. Any three succeeding elements in the list represent a triangle.
The vertices of triangle <code>i</code> (starting with 0 for the first triangle) are given by elements <code>i</code>, <code>i+1</code> and <code>i+2</code>.
In order to represent <code>n</code> triangles the list must therefore contain <code>n+2</code> elements.

==== Triangle Fans ====

Triangle Fans are similar to Triangle Strips.
However, in case of triangle fans, all triangles share the first element and the other two triangle vertices are provided in pairs of elements, representing a fan of triangles around a single vertex.
The vertices of triangle <code>i</code> (starting with 0 for the first triangle) are given by elements <code>0</code>, <code>i+1</code> and <code>i+2</code>.
To represent <code>n</code> triangles the list must therefore contain <code>n+2</code> elements, similar to triangle strips.

List of file formats

2010-02-07T10:42:45Z

Michaelfavor: /* OBJECT_BASE */ doh - fixed caps

== *.ac ==
This is the native format for 3D graphics written by the [http://www.ac3d.org/ AC3D] application (payware with free trial version). These files contains meshes, UV-mappings, texture paths and material definitions. The format is FlightGear's preferred (i.e. best supported) format. It's ASCII text and easy to edit by hand or via scripts. Many applications are able to import and/or export this format:

=== [http://www.blender3d.org/ Blender] ===
See File->Import/Export->AC3d (*.ac). [[Blender]] is a free and very powerful (some say: too powerful) 3D editor.

=== [http://www.openscenegraph.org/ Open Scenegraph Library] ===
The <tt>osgviewer</tt> demo is very useful for quickly looking at models.

=== [http://prettypoly.sourceforge.net/ ppe] ===
This is an unmaintained object editor that uses the same graphics library as FlightGear (plib). This has the advantage that objects look very much like in FlightGear (minus shader effects and shadows). Compiling ppe may be a challenge, though, and it's only useful for viewing, but hardly for editing objects.

=== threedconvert ===
This is a converter for all plib supported 3D formats and comes with FlightGear (see utils/Modeller/3dconvert.cxx). It can read and write <tt>*.ac</tt> files, but a written file may lack UV mapping or have other defects.

== *.rgb ==
These files are texture files in [http://en.wikipedia.org/wiki/Silicon_Graphics SGI] Image Format. This format supports multiple layers, transparency, compression, indexed colors, 8 bits and 16 bits per plane. Files of this format use different extensions, often to indicate the image properties, but in fact it's always the same format. The "official" extensions is <tt>*.sgi</tt>. Images with one layer are usually black/white (<tt>*.bw</tt>) or a mere alpha layer (<tt>*.a</tt>), with two layers black/white with alpha, with three layers red/green/blue (<tt>*.rgb</tt>), and with four layers red/green/blue/alpha (<tt>*.rgba</tt>). This, however, is only a convention and not mandated by the SGI image specification. SGI images can be uncompressed or [http://en.wikipedia.org/wiki/Run-length_encoding RLE-compressed], which is a lossless compression method.

FlightGear uses [http://plib.sourceforge.net/ plib] to read SGI images. They must not use 16 bits per plane and must have side lengths of 2<sup>n</sup>x2<sup>m</sup> (powers of 2), the size must be at least 4 pixels when using compressed textures (automatic feature in the osg branch). For example: 64x64, 256x256 or 128x2048 (but textures have '''square''' size inside the graphic card so a 16x1024 texture is really a 1024x1024 texture). Note that other sizes will '''not''' work, and FlightGear will use a red/white chequered texture instead! FlightGear textures ''shall'' be RLE-compressed, and as 'aggressively' as possible.

All better graphics applications should be able to read and write the format, but often they load SGI images without problems, but only write them properly when the <tt>*.sgi</tt> extension is used. Here are some free applications that create SGI images, along with some usage notes:

=== [http://www.gimp.org/ GIMP] ===
Either save the image with extension <tt>*.sgi</tt> and rename it afterwards, or choose in the file dialog "Select Filetype" -> "Silicon Graphics IRIS image". Save with "Aggressive RLE". (The remark about SGI not supporting that is wrong. This is compliant with the file specification from SGI itself.)

=== krita/kolourpaint ([http://www.kde.org/ KDE]) ===
KDE supports reading and writing of SGI images on the base library level, so ''all'' applications that can read/write images in general can also read/write SGI images. They are automatically saved in highest possible compression (more aggressive than GIMP :-)

=== convert ([http://www.imagemagick.org/ ImageMagick]/[http://www.graphicsmagick.org/ GraphicsMagick]) ===
Like with [[GIMP]], it's necessary to either call the target file <tt>*.sgi</tt> or to specify the file type explicitly via <tt>sgi:</tt> prefix:

$ convert foo.png foo.sgi # RIGHT
$ convert foo.png sgi:foo.rgb # RIGHT
$ convert foo.png foo.rgb # WRONG! This doesn't create an SGI image!

This creates SGI images with RLE compression by default.

Here is a bash script that you can run in the ./FlightGear/Aircraft directory to generate SGI image files for all of the PNG format files you have:

#!/bin/sh
for PNG in $(find -name '*.png')
do
SUBDIR=$(dirname $PNG)
FILEBASE=$(echo $PNG |awk -F / '{s=$(NF); n=split(s, sa, "."); delete sa[n]; for(sk in sa) {printf("%s.",sa[sk])}}')
RGB="$SUBDIR/${FILEBASE}rgb"
if [ ! -f $RGB ]
then
convert $PNG sgi:$RGB
fi
done

== *.stg ==
This entry is copied from $FG_ROOT/Docs/README.scenery, which is part of FlightGear >0.9.10.

stg files ("static terragear") define the static elements of a scenery "tile", including the terrain elevation data, airport geometry, and all static objects placed on this tile. Four of the available key words are followed by a string and four numbers. The meaning of these numbers is always the same and described under OBJECT_SHARED.

=== OBJECT_BASE ===
specifies the terrain elevation data file. These files are generated by the [http://www.terragear.org/ TerraGear] using the [[BTG File Format|BTG file format]], and have file extension ".btg" ("binary terragear"; there used to be an "*.atg" file, too, where
the 'a' stood for ASCII).

Example:

OBJECT_BASE 942050.btg

The entry may be anywhere in the 942050.stg file, on a separate line.

=== OBJECT ===
specifies an airport geometry 'drop-in' file. The scenery elevation file has cut out holes for airports, that are filled with such objects. They are usually called after the airport ICAO id:

Example:

OBJECT KSFO.btg

These files are, again, created by TerraGear tools and are usually gzipped, so you'll find that file stored as KSFO.btg.gz.

=== OBJECT_SHARED ===
add static object to the tile.

Example:

OBJECT_SHARED Models/Airport/tower.xml -122.501090 37.514830 15.5 0.00

Syntax:

OBJECT_SHARED <object-path> <longitude> <latitude> <elevation-m> <heading-deg>

The <object-path> is relative to the data directory (FG_ROOT). <elevation-m> is in meter and relative to mean sea-level (in the fgfs world). <heading-deg> is in degree, counter-clockwise with North being 0.0. Note
that this differs from about every other place in FlightGear, most notably the /orientation/heading-deg entry in the property system, which is clockwise. OBJECT_SHARED models are cached and reused. They are only once in memory and never freed. (See also the next section.)

=== OBJECT_STATIC ===
add static objects to the tile, just like OBJECT_SHARED. There are three differences to OBJECT_SHARED (apart from the name):

* the path is relative to the tile directory where the *.stg file with this entry is located. For example, relative to 130n30/w123n37/. This usually means that all 3D object files, textures, and XML animation files are in this tile directory, too.

* these objects are *not* cached and kept loaded, but rather freed with the tile (that is, when you leave that area).

* the animation XML files may contain Nasal blocks <nasal><load> and <nasal><unload> which are executed on loading/unloading.

Example:

OBJECT_STATIC ggb-fb.xml -122.4760494 37.81876042 0 105

=== OBJECT_SIGN ===
{{main article|Signs}}
defines taxiway or runway sign. The syntax is like that of OBJECT_SHARED entries, except that the path is replaced with a sign contents specification. This specification will probably be changed. Look at $FG_ROOT/Docs/README.scenery if you need to use this entry.

=== OBJECT_RUNWAY_SIGN ===
are experimental entries. Don't use them!

List of file formats

Michaelfavor: /* OBJECT_BASE */ added link to related page

== *.ac ==
This is the native format for 3D graphics written by the [http://www.ac3d.org/ AC3D] application (payware with free trial version). These files contains meshes, UV-mappings, texture paths and material definitions. The format is FlightGear's preferred (i.e. best supported) format. It's ASCII text and easy to edit by hand or via scripts. Many applications are able to import and/or export this format:

=== [http://www.blender3d.org/ Blender] ===
See File->Import/Export->AC3d (*.ac). [[Blender]] is a free and very powerful (some say: too powerful) 3D editor.

=== [http://www.openscenegraph.org/ Open Scenegraph Library] ===
The <tt>osgviewer</tt> demo is very useful for quickly looking at models.

=== [http://prettypoly.sourceforge.net/ ppe] ===
This is an unmaintained object editor that uses the same graphics library as FlightGear (plib). This has the advantage that objects look very much like in FlightGear (minus shader effects and shadows). Compiling ppe may be a challenge, though, and it's only useful for viewing, but hardly for editing objects.

=== threedconvert ===
This is a converter for all plib supported 3D formats and comes with FlightGear (see utils/Modeller/3dconvert.cxx). It can read and write <tt>*.ac</tt> files, but a written file may lack UV mapping or have other defects.

== *.rgb ==
These files are texture files in [http://en.wikipedia.org/wiki/Silicon_Graphics SGI] Image Format. This format supports multiple layers, transparency, compression, indexed colors, 8 bits and 16 bits per plane. Files of this format use different extensions, often to indicate the image properties, but in fact it's always the same format. The "official" extensions is <tt>*.sgi</tt>. Images with one layer are usually black/white (<tt>*.bw</tt>) or a mere alpha layer (<tt>*.a</tt>), with two layers black/white with alpha, with three layers red/green/blue (<tt>*.rgb</tt>), and with four layers red/green/blue/alpha (<tt>*.rgba</tt>).

This creates SGI images with RLE compression by default.

Building FlightGear - Windows

2010-01-27T16:17:36Z

Michaelfavor: formatting for shorter TOC

{{Main article|Building Flightgear}}

'''NOTE: Some parts of these instructions do not work correctly at this time, due to changes in the underlying software libraries. This page is a work in progress. The instructions should now be usable for all but building jpeglib and installing FlightGear'''

This section describes how to build [[FlightGear]] on Windows using Visual C++ 2008 Express Edition (the "free" for personal use version). These procedures will be very similar if you have the full Visual Studio 2008 and mostly similar if you're using older versions of Visual C++.

Keep in mind that FlightGear is a large project with external dependencies and compiling it is not a task for novice users. If you just want to fly, we recommend you get the binary distribution and have fun. If you intend to get hip deep in the code, please proceed...

== Requirements ==
Before you can compile FlightGear, you need to have the following installed on your computer:

===C++ compiler===
You may [http://www.microsoft.com/express/download/#webInstall download] the Express ("free" for personal use) version of Visual C++ 2008 from Microsoft. C++ Builder and Turbo C++ Explorer (by CodeGear, formerly by Borland) should work as well with some effort. We have not tried this.

Please note that when using MSVC++ Express, you'll probably want to download the full '''offline''' installation image file (iso) which -unlike the web installation- doesn't require any complicated and long-winded registration process. The direct link to the latest version (as of 11/2008) is [http://download.microsoft.com/download/E/8/E/E8EEB394-7F42-4963-A2D8-29559B738298/VS2008ExpressWithSP1ENUX1504728.iso] - after having downloaded the iso image, you'll either have to burn it or simply mount it in order to execute the installation.

You will also need the Platform SDK (Software Developer's Kit).

You can download the PSDK from http://www.microsoft.com/downloads/details.aspx?FamilyId=F26B1AA4-741A-433A-9BE5-FA919850BDBF&displaylang=en or http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdk-full.htm

Detailed installation instructions are available [https://forums.microsoft.com/Forums/ShowPost.aspx?PostID=1995837&SiteID=1 here] (and [https://forums.microsoft.com/Forums/ShowPost.aspx?PostID=2888051&SiteID=1]).

===CVS===
FlightGear uses [[FlightGear CVS|CVS]] (Concurrent Versions System) for version control. You will need a CVS client if you want to download the latest (development) source code for both FlightGear and SimGear. Traditionally, these are command line tools, but TortoiseCVS provides a graphic interface for Windows users. Download the installer for the latest stable version of [http://www.tortoisecvs.org/download.shtml TortoiseCVS], run the installer, using all of its default settings (the installation destination folder is up to you). It will ask you to restart the computer when it's finished <grumble>. Do that.

===SVN===
OpenSceneGraph (OSG) uses Subversion (SVN) for version control. You will need an SVN client if you want to use the latest (development) source code for OpenSceneGraph. TortoiseSVN provides a graphic interface for Windows users. Download the installer for the latest stable version of [http://tortoisesvn.net/downloads TortoiseSVN], run the installer, using all of its default settings (the installation destination folder is up to you).

== Dependencies ==

FlightGear is dependent on quite a number of external libraries. You do not need to compile all of them yourself, but you will at least need to have their development version installed.

* Boost
* ALut, OpenAL and pthreads. These are listed here as one dependency because it's made available as a single package by a FlightGear project member.
* zlib
* jpeglib
* [[Plib]] - portability libraries and scene graph.
* [[OpenSceneGraph]]
* [[SimGear]] - Simulation support libraries that are developed mainly by the same people who develop FlightGear, though it can be and is used for other purposes. If you are building FlightGear from CVS, you need the CVS version of SimGear. If you have strange FlightGear build errors, check that you have an up-to-date version of SimGear built and installed.

The dependencies are introduced in the steps below in roughly the order that you will need to get them.

== Directory Structure ==

As noted above, FlightGear depends on several other software packages. The Visual C++ project files that are maintained in CVS for both SimGear and FlightGear assume that these dependencies can be found within a very specific directory structure. In these examples, the root of the FlightGear related directories is '''C:\FlightGear\'''. This part is actually up to you; you could choose a completely different name and drive location.

All other directories shown under this project root must follow the directory structure shown below:

C:\FlightGear\boost_1_39_0\
C:\FlightGear\simgear\
C:\FlightGear\simgear\simgear\
C:\FlightGear\install\msvc90\OpenSceneGraph\include\
C:\FlightGear\3rdParty\include\
C:\FlightGear\plib
C:\FlightGear\flightgear

If you continue to follow the instructions in this wiki, you will end with the proper directory structure that is shown above.

== Getting '''Boost 1.39.0''' ==

* '''Step 1''' - Download Boost packaged release Version 1.39.0 (about 188 MB) from
http://sourceforge.net/projects/boost/files/boost/1.39.0/boost_1_39_0.zip/download (direct link) or from the project releases page at http://www.boost.org/users/download/#releases

* '''Step 2''' - Extract the contents of the boost archive in your '''\FlightGear''' directory. This will create a subdirectory named '''boost_1_39_0''' where the boost libraries and include files reside.

== Getting "3rdParty" ALut, OpenAL and pthreads ==

Olaf Flebbe has provided an archive containing the following FlightGear dependencies:

ALut
OpenAL
pthreads

Download the archive from http://www.oflebbe.de/FlightGear/3rdParty-2008-01-30.zip

Extract the archive in your FlightGear project root directory, '''C:\FlightGear\''' in these instructions. This will create the directory '''3rdParty''' under your project root directory.

== Getting zlib ==

* '''Step 1''' - Download the latest zlib binary package here http://sourceforge.net/projects/gnuwin32/files/zlib/1.2.3/zlib-1.2.3-lib.zip/download (direct link) or view the release page here http://sourceforge.net/projects/gnuwin32/files/zlib/1.2.3/

* '''Step 2''' - Extract the archive you downloaded in Step 1 in the "3rdParty" directory under your FlightGear project root directory.

* '''Step 3''' - As of zlib version 1.2.3, you must edit line 287 of the file "3rdParty\include\zconf.h" from "#if 1" to "#if 0" to avoid compiler errors when compiling SimGear against zlib.

== Getting jpeglib ==

* '''Step 1''' - Download the latest jpeglib source package here http://www.ijg.org/

* '''Step 2''' - This is a simple way to compile that should work with all versions of MSVC.
Open a command prompt and navigate to the folder where you have extracted the sources.
Type the following commands:
<pre>
copy jconfig.vc jconfig.h
copy makefile.vc makefile
</pre>
(this will copy the preconfigured Visual C configuration and makefile).

Then on the same command prompt type the following command to build the library:
<pre>
nmake nodebug=1
</pre>

== Getting plib ==

You may download a prebuilt version of plib from http://www.oflebbe.de/FlightGear/plib-2007-04-16.zip (direct link) or visit Olafe's Compiling FlightGear page at http://www.oflebbe.de/FlightGear/index.html If you use this prebuilt, just extract the archive file's contents in your FlightGear project root directory. This will create the subdirectory '''plib'''.

The above plib package does not include debug libaries, only release. There have also been some bug fixes and changes to since that package was created, so you may wish to use the latest development version, 1.8.5-rc1 which you may download here http://sourceforge.net/projects/plib/ One annoying bug that was fixed caused joystick models to not be recognized automatically on Windows Vista (and maybe XP).

Going this route means that you must compile plib yourself by following the instructions below:

* '''Step 1''' - Download the latest plib source tarball from http://sourceforge.net/projects/plib/ and extract it in some location that is NOT in your FlightGear project root directory. This will create a subdirectory named '''plib-1.8.5-rc1'''

* '''Step 2''' - Double-click the file plib-1.8.5-rc1\plib.dsw. This should launch Visual C++ which will ask if you want to convert the project file; answer "Yes to all" at the convert prompt.

* '''Step 3''' - Build the debug version of the plib libraries first by setting the VC++ Solution Configuration for Debug and hitting the F7 key.

Build the release version of the plib libraries next by setting the VC++ Solution Configuration for Release and hitting the F7 key.

NOTE: as of this writing, 5 compile errors in 4 files will occur. In each case, a typecast of '''(char*)''' must be added in order to compile without error using VC++ 2008 (VC90).

* '''Step 4''' - Create the subdirectory '''plib''' in your FlightGear project root directory.

Example:
C:\FlightGear\plib

* '''Step 5''' - Copy all of the files in your plib-1.8.5-rc1 directory that have the extensions "h", "lib" and "pdb" to the new plib directory under your FlightGear project root directory.

== Getting OpenSceneGraph (OSG)==

* '''Step 1'''

To build SimGear and FlightGear from CVS head, you'll usually need the latest version of OSG. OSG from SVN head might be the best choice, but we don't have OSG for Windows build instructions prepared yet.

You can however try and follow the building instructions from the OSG wiki, which make use of CMake: [http://www.openscenegraph.org/projects/osg/wiki/Build/CMake/]

Download the latest Windows binaries from this page: [http://www.openscenegraph.org/downloads/stable_releases/OpenSceneGraph-2.8.1/binaries/Windows/VisualStudio9/]

Get the archive(s) named "openscenegraph-all[...]". Get both the Release and Debug versions if you expect to do any debug builds of FlightGear. Otherwise, just the Release version should be fine.

* '''Step 2''' - Create a the following directure structure under your FlightGear project root directory: "install\msvc90\"

Example:

C:\FlightGear\install\msvc90\

I have no idea why that directory structure was chosen, but that's what the MS VC++ project file(s) in FG CVS expect.

* '''Step 3''' - Extract the OSG archive(s) you downloaded in Step 1 in the directory you created in Step 2.
* '''Step 4''' - Rename the resulting "OpenSceneGraph-[version]" directory to simply "OpenSceneGraph".

== Getting and compiling SimGear ==

* '''Step 1''' - Navigate to the base folder for your FlightGear stuff; In this example, we've chosen "C:\FlightGear"

In Windows Explorer, select the "C:\FlightGear" folder and right-click on it. From the resulting pop-up menu, choose "CVS Checkout". On the "Module" tab, enter the following in the CVSROOT field:

:pserver:cvsguest@cvs.simgear.org:/var/cvs/SimGear-0.3

At the "Module" section near the bottom of the "Module" tab, click the "Fetch List" button. You will see some brief action and may see an error and a prompt for a password. Enter "guest" for the password (without the quote symbols). From the drop-down "Module" list, select "source" and click the "OK" button to begin the checkout.

* '''Step 2''' - Since all the source code will be downloaded into a directory called '''source''', you will need to rename that directory to '''simgear'''.

Navigate to simgear\projects\VC90 and double-click on the file '''SimGear.vcproj'''. This should launch Visual C++ with the SimGear project loaded.

* '''Step 3''' - Build SimGear, either Release, Debug or both using VC++ 2008 (9.0)

''Note:'' with the default settings, Visual C++ will yield many compiler warnings. Unfortunately, this is normal.

== Getting and compiling FlightGear ==

* '''Step 1'''
Make a base folder for your FlightGear stuff; In this example, we've chosen "C:\FlightGear"

In Windows Explorer, select the "C:\FlightGear" folder and right-click on it. From the resulting pop-up menu, choose "CVS Checkout". On the "Module" tab, enter the following in the CVSROOT field:

:pserver:cvsguest@cvs.flightgear.org:/var/cvs/FlightGear-0.9

At the "Module" section near the bottom of the "Module" tab, click the "Fetch List" button. You will see some brief action and may see an error and a prompt for a password. Enter "guest" for the password (without the quote symbols). From the drop-down "Module" list, select "source" and click the "OK" button to begin the checkout.

A directory with the name '''source''' will then be created with all of Flightgear's source code downloaded into it. Rename this directory from '''source''' to '''flightgear'''.

* '''Step 2'''

Build either the Debug or Release version FlightGear as desired.

* '''Step 3'''

TODO: Installation.

==Checking out the FlightGear data==
The binary distribution package contains '''data''' for only a small subset of the existing aircraft and other objects. The instructions below tell you how to obtain the full set of data, in their latest, greatest form.

Make a base folder for your FlightGear stuff; In this example, we've chosen "C:\FlightGear"

In Windows Explorer, select the "C:\FlightGear" folder and right-click on it. From the resulting pop-up menu,
choose "CVS Checkout...". On the "Module" tab, enter the following in the CVSROOT field:

:pserver:cvsguest@cvs.flightgear.org:/var/cvs/FlightGear-0.9

At the "Module" section near the bottom of the "Module" tab, click the "Fetch List" button. You will see some brief action and may see an error and a prompt for a password. Enter "guest" for the password (without the quote symbols). From the drop-down "Module" list, select "data" and click the "OK" button to begin the checkout.

The result of the checkout is a directory called C:\FlightGear\data. To use this data directory with the FlightGear program, you can either (a) move it to C:\Program Files\FlightGear\ directory or (b) direct FlightGear to the actual location of this data directory from the command line or within the fgrun launcher application.

== Developer Documentation ==
=== RFC Topics ===
'''Clarification:''' In its current form, the RFC section is exclusively based on and covered by previous mailing list and forum discussions (as well as various wiki entries), as such it is not supposed to reflect work in progress (RFC="Request For Comments" and not WIP), but is rather to be seen as an attempt to provide comprehensive analyses and summaries of key issues identified in various FlightGear related discussions and feature requests (which are to be linked to in the corresponding resource sections, if that didn't yet take place, it's because of most of these RFCs being indeed WIP).

Thus, RFC entries are not meant to imply anyone "working" on any of these issues, in fact only because an RFC entry is listed here doesn't necessarily mean that work on that particular issue is prioritized or generally endorsed by the FlightGear community.
These RFC documents are however intended to hopefully help increase and maintain awareness of long-standing issues and challenges affecting FlightGear's evolution and overall development progress in order to solicit community feedback about possible approaches to address these in an efficient and structured fashion.
Anybody is welcome to comment on, help refine and develop new strategies to tackle the challenges presented in these and future RFCs.

* [[Autopilot Enhancements]] - enhancing the autopilot infrastructure.
* [[Backwards Compatibility Initiative]] - discussing possible ways to improve FlightGear's backwards compatibility.
* [[Distributed Interactive Simulation|Multiplayer Enhancements]] - discussing possible steps to enhance FlightGear's Multiplayer support.
* [[Modularizing, parallelizing and distributing FlightGear]] - splitting fgfs into distinct components that are to be run as separate processes using the property tree for IPC purposes in order to leverage SMP platforms and distribution/remoting to help FlightGear become more scalable.

[[Image:FGlogo.jpg|left]] '''[[FlightGear]]''' is a sophisticated, realistic flight-simulator, created entirely by volunteers, and released as free, open-source [[GNU General Public License|GPL]] software, available for download [http://www.flightgear.org/Downloads/ here]. FlightGear has a graphical user interface realistic enough for real-life pilot training, and mathematical flight models accurate enough serious scientific research. FlightGear's free and open license also makes it great for educational exploration, or just for fun.

FlightGear can be expanded and improved by anyone interested in [[Volunteer|contributing]]. The complete project source code is available via [[CVS]], licensed under the [[GNU General Public License]]. FlightGear's open architecture encourages exploring related flight simulator concepts, and has inspired a number of [[FlightGear related projects|related projects]].

FlightGear comes with a set of illustrated documentation, notably "The Manual", which is available as [http://mapserver.flightgear.org/getstart.pdf PDF] and [http://www.flightgear.org/Docs/getstart/getstart.html HTML].

FlightGear [[FlightGear 1.9.1|version 1.9.1]] was released in January 2009.

KLN89

2010-01-25T19:23:03Z

Michaelfavor: minor update

A KLN89b GPS instrument, based on code committed by Dave Luff, worked in FlightGear version 0.9(?) but stopped working in version 1.0.0

There is no clear reason why the KLN89 doesn't appear in the current version of the C172.

Fixing some (hopefully minor) issues may get it to work as originally designed.

There may be ZKV500 or KLN90 GPS instruments in the b1900d, DHC3, GROB-115 and other aircraft.

FlightGear history

2010-01-25T08:17:12Z

Michaelfavor: /* Sources */ added link to ftp archive

FlightGear development started with an online proposal in 1996, using custom 3D graphics code. Development of an [[OpenGL]] based version was spearheaded by Curtis Olson starting in 1997. Many people have contributed to the project in the years since its inception.

FlightGear incorporated other open-source resources, including the LaRCsim flight model from NASA, and freely available elevation data. The first working binaries, using OpenGL for 3D graphic code, came out in 1997. Enthusiastic development of newer versions for several years resulted in progressively more stable and advanced versions. By 2001, the team was releasing new beta versions regularly, and by 2005, the maturity of software lead to more widespread reviews, and increased popularity. 2007 marked a formal transition out of beta development with the release of version 1.0.0, ten years after FlightGear's first release in 1997.

In 2008, version 1.9.0 of FlightGear included a major change from [[PLIB]] to [[OSG]], which caused the temporarily loss of some features like 3D clouds and shadows, while newly added features, such as particles, imparted another degree of realism to the simulation.

===Beginnings (1996-1997)===
Development formally started in the late-1990s with an online proposal and code being written in 1996, but using custom 3D graphics code. Development of an [[OpenGL]] based version was spearheaded by Curtis Olsen starting in 1997, after the initial start in 1996. A large community response lead to many contributing to the project from its start in late '90s up to the present.

Rather than start entirely from scratch, FlightGear developers made use of the LaRCsim flight model from NASA, with OpenGL for 3D graphic code, and freely available elevation data. First working binaries came out in 1997, with an intense updating of newer versions for several years resulting in progressively more stable and advanced programs.

===Versions 0.7–0.9 (2001–2003)===
By 2001, the team was releasing new beta versions regularly (0.7.x, 0.8.0, over 2001-2003) and with 0.9.xx (2003-2006). Later in the decade, the rate of final public releases slowed, but had larger amounts of content (0.9.10, 1.0.0 etc.). The maturity of software by 2005 lead to more widespread reviews, and increased popularity.

===Version 0.9.0-0.9.11 (2002-2007)===
The use of version numbers slowed dramatically after the late 2002 release of version 0.9.0. Versions 0.9.9 (2005) and 0.9.10 (2006) had about 8 all-new or redone [[aircraft]] adding to a total of 70-90 aircraft. FlightGear 0.9.10 won Softpedia's "Pick" award (5 out of 5 stars) on June 3, 2006 as well as the "100% CLEAN" Softpedia award.

Behind the scenes there was a 0.9.11-pre1 released in 2007 that ended up being superseded by FlightGear 1.0. The pre-version had about 33 new or redone aircraft.

[[Image:FG-A-10.jpg|thumb|270px|3D Cockpit panel for [[A-10]] in version 1.0.0 in 2008]]
===Version 1.0 (2008)===
The version number marked a formal transition out of beta development since software's first release in 1997, ten years prior.

===Version 1.9.0 (2008)===
At the time version 1.9.0 was released FlightGear switched from [[PLIB]] to [[OSG]], which caused the temporarily lost of some of the features like 3D clouds and shadows. On the contrary new features such as particles add another degree of realism to the simulation. Most aircraft developed for OSG do not work with older versions. The users is able to choose out of 230 aircraft provided with 1.9.0, altough only a few are included in the base package.

'''San Jose International Airport''' is the main commercial airport serving the South Bay Area of the San Francisco Bay. In real life traffic, it handles less than a third of the passengers of [[San Francisco International Airport]] despite San Jose being the largest city in the Bay Area. It also has fewer passengers than [[Oakland International Airport]]. It is located relatively near downtown compared to other airports and has become cramped with little room to expand.

==Airlines==
SJC is not a hub or focus city for any airline. However, it was once a hub for American Airlines in the early 90's, but this hub was reduced and never being brought back. Southwest Airlines does have a good presence at the airport, being the largest carrier there.

==Runways==
KSJC has 3 runways. The two 3353 meters ones are used mostly by commercial traffic and large private jets, and the smaller one to the west is used by general aviation traffic. The larger runways are shortened by displaced thresholds of 305 m (1000 feet) on the northwestern ends and 762 m (2500 feet) ones on the southeastern ends. This is mainly to comply with noise restrictions, as well as the approach method which is generally straight over downtown.

Most landings are on the 30L end of 12R/30L with most takeoffs on the 30R runway end.

Runway 12L/30R was once around 1,333 m before being lengthened to its current length around 2001.

==Scenery==
There are not very many scenery objects available for the airport, but a tower model is included, and a model of Terminal A is in the works.

'''FlightGear Flight Simulator''' (often shortened to '''FlightGear''' or '''FGFS''') is a sophisticated free, completely open-source flight simulator framework, created by volunteers. FlightGear is released under the terms of the [[GNU General Public License]]. FlightGear is mostly written in the C++ programming language.

Increasingly detailed and realistic versions of FlightGear have been released every year since the project was started in 1996.

The latest public release is available as a free download at [http://www.flightgear.org/Downloads/ http://www.flightgear.org/Downloads/], with specific builds for a variety of operating systems including Microsoft Windows (Win 32), Mac OS X, Linux, IRIX, and Solaris.

==History==
{{main article|FlightGear History}}

FlightGear development started with an online proposal in 1996, using custom 3D graphics code. Development of an [[OpenGL]] based version was spearheaded by Curtis Olson starting in 1997. Many people have contributed to the project in the years since its inception.

FlightGear incorporated other open-source resources, including the LaRCsim flight model from NASA, and freely available elevation data. The first working binaries, using OpenGL for 3D graphic code, came out in 1997. Enthusiastic development of newer versions for several years resulted in progressively more stable and advanced versions. By 2001, the team was releasing new beta versions regularly, and by 2005, the maturity of software lead to more widespread reviews, and increased popularity. 2007 marked a formal transition out of beta development with the release of version 1.0.0, ten years after FlightGear's first release in 1997.

[[Image:FG-A-10.jpg|thumb|270px|3D Cockpit panel for [[A-10]] in version 1.0.0 in 2008]]

In 2008, version 1.9.0 of FlightGear included a major change from [[PLIB]] to [[OSG]], which caused the temporarily loss of some features like 3D clouds and shadows, while newly added features, such as particles, imparted another degree of realism to the simulation.

==Software==

The simulation engine in FlightGear is called [[SimGear]]. It is used both as an end-user application and in academic and research environments, for the development and pursuit of flight simulation ideas.

This customizability of FlightGear is illustrated by the wide range of aircraft models that are available in FlightGear, from [[:Category:Gliders|glider]]s to [[Helicopter]]s, and from [[:Category:Airliners|airliners]] to [[Military aircraft|fighter jets]]. These aircraft models have been contributed by many different people.

The FlightGear aircraft use one of three main data models JSBSim, YAsim, or UIUC as of version 0.9.10. Currently only one terrain engine is used, TerraGear. Weather effects include 3D clouds, lighting effects, and time of day.

===Flight Dynamics Models===
[[Flight Dynamics Models]] (FDM) are how the flight for an aircraft is simulated in the program. FlightGear uses a variety of internally written and imported flight model projects. Any aircraft must be programmed to use one of these models. Currently FlightGear is the only flight graphical flight simulator all the FDM are used for, and UIUC and YASim were developed specifically for FlightGear.

Early version used a FDM based on [[LaRCsim]] by NASA, which was replaced with more flexible FDM.

*[[JSBSim]] - the default flight dynamics model software since 2000.
*[[YASim]] - another FDM using different calculation method. Introduced starting in 0.7.9 in 2002.
*[[UIUC]] - another included FDM, developed by the UIUC Applied Aerodynamics Group at University of Illinois at Urbana-Champaign, also made use of LaRCsim.
*Flight Gear can also be setup to render using inputs from an external FDM source, such as from Matlab.
*Other custom FDM for a specific aircraft type have been written, such as for lighter than air aircraft.

===FlightGear dependencies===
Unlike commercial software titles, the main output of the project is simply the release of a collection of code. To turn it into a usable program it must be compiled for a given platform. The software libraries used to create FlightGear have varied over time. The main one is [[SimGear]], which is the underlying sim engine for FlightGear. [[TerraGear]] is not a dependency, but simply a name for the default terrain data program in FlightGear. OpenAL is used for sound/audio software, including support for SDL (since 0.9.5). PLIB is used for hardware support routines, formerly used for sound support also which was taken over by OpenAL. [[OpenGL]] is used for its integrated 3D graphics routines, and other hardware acceleration (namely DirectX) is not supported. [[OpenSceneGraph]] is also integrated into FlightGear. Finally, Simple DirectMedia Layer is a software library which is used for compiling. Some of the dependencies vary depending on which platform the code is being compiled for. FlightGear users must either compile the code themselves, or find a third party to release a binary, if it is not among the ones available from the project.

==Hardware==
Hardware needed for FlightGear is narrow to machines that support [[OpenGL]] and 3D hardware acceleration, with NVIDIA hardware having better support. Early versions had support for 3dfx cards, though this dropped as hardware requirements increased.

[[Image:Fgrun-page2.jpg|thumb|left|270px|The [[FlightGear Launch Control|FlightGear Launcher]]]]
==Add-ons and customization==
There are programs that are either integrated into FlightGear (dependencies) or perform a function with it. Some of these are included in the release of FlightGear for a specific platform but made by the project, while others are independently distributed but are hosted by the FlightGear project.

One major additional software is the actual interface for launching an executable of FlightGear. For most of its early life FlightGear was only run through [[command line]] interfaces. However, the FlightGear Launch Control has been included with the ''[[FG launcher]]'' front-end since 0.9.3 in 2003. ''[[KFreeFlight]]'' is a launcher/front-end for KDE. ''FGTools'' is an alternative windows launcher front-end. ''FGKicker'' is a GTK+ based front-end.

Other significant programs include editors and projects for Terrain Data. ''[[Atlas]]'' is a chart/map support for FlightGear; ''[[Kelpie Flight Planner]]'' is a Java based flight planner for FlightGear. ''[[FlightGear Scenery Designer]]'' is a FlightGear scenery editor for working with terrain data. The ''[[World Custom Scenery Project]]'' is a project coordinating custom scenery efforts. Finally, ''[[TaxiDraw]]'' is an editor for airport runways and taxiways.

===Aircraft===
{{Main article|Table of models}}

FlightGear started out with an aircraft included in NASA's LaRCsim, a Navion, which was replaced by a Cessna 172 by 2000. UIUC as well as JSBsim development brought several more aircraft with them, as did the development of YASim which have since become the main FDM used in FG. Over 230 aircraft are available for version 1.9.0, although only a few are included in the base package.

[[Image:EHAM.jpg|thumb|270px|[[Boeing 737-300|Boeing 733]] docked in the [[EHAM]] scenery]]
===Scenery===
{{Main article|Scenery}}
FlightGears [[world scenery]] project contains elevation and landclass data of the enitre world. Objects -like terminals, windmills and bridges- are collected in the [[FlightGear Scenery Database|Scenery Database]].

===Networking and multi-display===
Several networking options allow FlightGear to communicate with other instances of FlightGear. A [[Multiplayer Howto|multiplayer]] protocol is available for using FlightGear on a local network in a multi aircraft environment. This could be used for formation flight or [[ATC|control tower]] simulation. Multiplayer was soon expanded to allow playing over the internet. Other features include a Google maps based moving up that allows users to observe where other players are.

Several instances of FlightGear can be synchronized to allow for a multi-monitor environment. If all instances are running at the same frame rate consistently, it is possible to get good and tight synchronization between displays.

==FlightGear code vs. binaries==
Unlike most commercial software, the project release dates only apply to a release of code, not an executable program. To create a runnable program the code must be compiled, which requires several specific libraries, including some general ones and, in some cases some platform specific ones. However, since this too difficult for most mainstream users, other contributors will work to make binaries available for a specific platform and operating system. These packages vary in their stability, performance, dependencies, and how up to date they are with the code base. For example, some older binaries work on Mac OS 9 but newer releases require specific Mac OS X versions.

For example, by late 2007 the latest code release was 0.9.11-pre1 (pre-release) and 0.9.10 (final). However, the actual binaries available vary significantly. Examples of actual binaries available a year after the release of the 0.9.10 code release:

*Win-32 has ~138 Mb package (v0.9.10) (For Windows 98, 2000, ME, 32-bit XP)
*Linux- pre-built packages for specific Linux distributions
**Slackware package (v0.9.10), Fedora Core 2,3,4 packages (v0.9.10), Pardus (v0.9.10), Debian (v0.9.9)
*Solaris packages either for it running on either SPARC or x86 processors.
** SPARC (v0.9.8), x86 (v0.9.9)
*Silicon Graphics IRIX
**SGI binaries for (v0.9.9)
*Mac OS X
**Mac OS 10.4 (v0.9.10)
**Mac OS 10.3 (v0.9.9)
*FreeBSD has a package for(v0.9.10)

Michaelfavor: copied history introduction from FlightGear

FlightGear development started with an online proposal in 1996, using custom 3D graphics code. Development of an [[OpenGL]] based version was spearheaded by Curtis Olson starting in 1997. Many people have contributed to the project in the years since its inception.

FlightGear incorporated other open-source resources, including the LaRCsim flight model from NASA, and freely available elevation data. The first working binaries, using OpenGL for 3D graphic code, came out in 1997. Enthusiastic development of newer versions for several years resulted in progressively more stable and advanced versions. By 2001, the team was releasing new beta versions regularly, and by 2005, the maturity of software lead to more widespread reviews, and increased popularity. 2007 marked a formal transition out of beta development with the release of version 1.0.0, ten years after FlightGear's first release in 1997.

In 2008, version 1.9.0 of FlightGear included a major change from [[PLIB]] to [[OSG]], which caused the temporarily loss of some features like 3D clouds and shadows, while newly added features, such as particles, imparted another degree of realism to the simulation.

===Beginnings (1996-1997)===
Development formally started in the late-1990s with an online proposal and code being written in 1996, but using custom 3D graphics code. Development of an [[OpenGL]] based version was spearheaded by Curtis Olsen starting in 1997, after the initial start in 1996. A large community response lead to many contributing to the project from its start in late '90s up to the present.

Rather than start entirely from scratch, FlightGear developers made use of the LaRCsim flight model from NASA, with OpenGL for 3D graphic code, and freely available elevation data. First working binaries came out in 1997, with an intense updating of newer versions for several years resulting in progressively more stable and advanced programs.

===Versions 0.7–0.9 (2001–2003)===
By 2001, the team was releasing new beta versions regularly (0.7.x, 0.8.0, over 2001-2003) and with 0.9.xx (2003-2006). Later in the decade, the rate of final public releases slowed, but had larger amounts of content (0.9.10, 1.0.0 etc.). The maturity of software by 2005 lead to more widespread reviews, and increased popularity.

===Version 0.9.0-0.9.11 (2002-2007)===
The use of version numbers slowed dramatically after the late 2002 release of version 0.9.0. Versions 0.9.9 (2005) and 0.9.10 (2006) had about 8 all-new or redone [[aircraft]] adding to a total of 70-90 aircraft. FlightGear 0.9.10 won Softpedia's "Pick" award (5 out of 5 stars) on June 3, 2006 as well as the "100% CLEAN" Softpedia award.

Behind the scenes there was a 0.9.11-pre1 released in 2007 that ended up being superseded by FlightGear 1.0. The pre-version had about 33 new or redone aircraft.

[[Image:FG-A-10.jpg|thumb|270px|3D Cockpit panel for [[A-10]] in version 1.0.0 in 2008]]
===Version 1.0 (2008)===
The version number marked a formal transition out of beta development since software's first release in 1997, ten years prior.

===Version 1.9.0 (2008)===
At the time version 1.9.0 was released FlightGear switched from [[PLIB]] to [[OSG]], which caused the temporarily lost of some of the features like 3D clouds and shadows. On the contrary new features such as particles add another degree of realism to the simulation. Most aircraft developed for OSG do not work with older versions. The users is able to choose out of 230 aircraft provided with 1.9.0, altough only a few are included in the base package.

'''FlightGear Flight Simulator''' (often shortened to '''FlightGear''' or '''FGFS''') is a sophisticated free, completely open-source flight simulator framework, created by volunteers. FlightGear is released under the terms of the [[GNU General Public License]]. FlightGear is mostly written in the C++ programming language.

Increasingly detailed and realistic versions of FlightGear have been released every year since the project was started in 1996.

The latest public release is available as a free download at [http://www.flightgear.org/Downloads/ http://www.flightgear.org/Downloads/], with specific builds for a variety of operating systems including Microsoft Windows (Win 32), Mac OS X, Linux, IRIX, and Solaris.

==History==
{{main article|FlightGear History}}

FlightGear development started with an online proposal in 1996, using custom 3D graphics code. Development of an [[OpenGL]] based version was spearheaded by Curtis Olsn starting in 1997. Many people have contributed to the project in the years since its inception.

FlightGear incorporated other open-source resources, including the LaRCsim flight model from NASA, and freely available elevation data. The first working binaries, using OpenGL for 3D graphic code, came out in 1997. Enthusiastic development of newer versions for several years resulted in progressively more stable and advanced versions. By 2001, the team was releasing new beta versions regularly, and by 2005, the maturity of software lead to more widespread reviews, and increased popularity. 2007 marked a formal transition out of beta development with the release of version 1.0.0, ten years after FlightGear's first release in 1997.

[[Image:FG-A-10.jpg|thumb|270px|3D Cockpit panel for [[A-10]] in version 1.0.0 in 2008]]

In 2008, version 1.9.0 of FlightGear included a major change from [[PLIB]] to [[OSG]], which caused the temporarily loss of some features like 3D clouds and shadows, while newly added features, such as particles, imparted another degree of realism to the simulation.

==Software==

The simulation engine in FlightGear is called [[SimGear]]. It is used both as an end-user application and in academic and research environments, for the development and pursuit of flight simulation ideas.

This customizability of FlightGear is illustrated by the wide range of aircraft models that are available in FlightGear, from [[:Category:Gliders|glider]]s to [[Helicopter]]s, and from [[:Category:Airliners|airliners]] to [[Military aircraft|fighter jets]]. These aircraft models have been contributed by many different people.

The FlightGear aircraft use one of three main data models JSBSim, YAsim, or UIUC as of version 0.9.10. Currently only one terrain engine is used, TerraGear. Weather effects include 3D clouds, lighting effects, and time of day.

===Flight Dynamics Models===
[[Flight Dynamics Models]] (FDM) are how the flight for an aircraft is simulated in the program. FlightGear uses a variety of internally written and imported flight model projects. Any aircraft must be programmed to use one of these models. Currently FlightGear is the only flight graphical flight simulator all the FDM are used for, and UIUC and YASim were developed specifically for FlightGear.

Early version used a FDM based on [[LaRCsim]] by NASA, which was replaced with more flexible FDM.

*[[JSBSim]] - the default flight dynamics model software since 2000.
*[[YASim]] - another FDM using different calculation method. Introduced starting in 0.7.9 in 2002.
*[[UIUC]] - another included FDM, developed by the UIUC Applied Aerodynamics Group at University of Illinois at Urbana-Champaign, also made use of LaRCsim.
*Flight Gear can also be setup to render using inputs from an external FDM source, such as from Matlab.
*Other custom FDM for a specific aircraft type have been written, such as for lighter than air aircraft.

===FlightGear dependencies===
Unlike commercial software titles, the main output of the project is simply the release of a collection of code. To turn it into a usable program it must be compiled for a given platform. The software libraries used to create FlightGear have varied over time. The main one is [[SimGear]], which is the underlying sim engine for FlightGear. [[TerraGear]] is not a dependency, but simply a name for the default terrain data program in FlightGear. OpenAL is used for sound/audio software, including support for SDL (since 0.9.5). PLIB is used for hardware support routines, formerly used for sound support also which was taken over by OpenAL. [[OpenGL]] is used for its integrated 3D graphics routines, and other hardware acceleration (namely DirectX) is not supported. [[OpenSceneGraph]] is also integrated into FlightGear. Finally, Simple DirectMedia Layer is a software library which is used for compiling. Some of the dependencies vary depending on which platform the code is being compiled for. FlightGear users must either compile the code themselves, or find a third party to release a binary, if it is not among the ones available from the project.

==Hardware==
Hardware needed for FlightGear is narrow to machines that support [[OpenGL]] and 3D hardware acceleration, with NVIDIA hardware having better support. Early versions had support for 3dfx cards, though this dropped as hardware requirements increased.

[[Image:Fgrun-page2.jpg|thumb|left|270px|The [[FlightGear Launch Control|FlightGear Launcher]]]]
==Add-ons and customization==
There are programs that are either integrated into FlightGear (dependencies) or perform a function with it. Some of these are included in the release of FlightGear for a specific platform but made by the project, while others are independently distributed but are hosted by the FlightGear project.

One major additional software is the actual interface for launching an executable of FlightGear. For most of its early life FlightGear was only run through [[command line]] interfaces. However, the FlightGear Launch Control has been included with the ''[[FG launcher]]'' front-end since 0.9.3 in 2003. ''[[KFreeFlight]]'' is a launcher/front-end for KDE. ''FGTools'' is an alternative windows launcher front-end. ''FGKicker'' is a GTK+ based front-end.

Other significant programs include editors and projects for Terrain Data. ''[[Atlas]]'' is a chart/map support for FlightGear; ''[[Kelpie Flight Planner]]'' is a Java based flight planner for FlightGear. ''[[FlightGear Scenery Designer]]'' is a FlightGear scenery editor for working with terrain data. The ''[[World Custom Scenery Project]]'' is a project coordinating custom scenery efforts. Finally, ''[[TaxiDraw]]'' is an editor for airport runways and taxiways.

===Aircraft===
{{Main article|Table of models}}

FlightGear started out with an aircraft included in NASA's LaRCsim, a Navion, which was replaced by a Cessna 172 by 2000. UIUC as well as JSBsim development brought several more aircraft with them, as did the development of YASim which have since become the main FDM used in FG. Over 230 aircraft are available for version 1.9.0, although only a few are included in the base package.

[[Image:EHAM.jpg|thumb|270px|[[Boeing 737-300|Boeing 733]] docked in the [[EHAM]] scenery]]
===Scenery===
{{Main article|Scenery}}
FlightGears [[world scenery]] project contains elevation and landclass data of the enitre world. Objects -like terminals, windmills and bridges- are collected in the [[FlightGear Scenery Database|Scenery Database]].

===Networking and multi-display===
Several networking options allow FlightGear to communicate with other instances of FlightGear. A [[Multiplayer Howto|multiplayer]] protocol is available for using FlightGear on a local network in a multi aircraft environment. This could be used for formation flight or [[ATC|control tower]] simulation. Multiplayer was soon expanded to allow playing over the internet. Other features include a Google maps based moving up that allows users to observe where other players are.

Several instances of FlightGear can be synchronized to allow for a multi-monitor environment. If all instances are running at the same frame rate consistently, it is possible to get good and tight synchronization between displays.

==FlightGear code vs. binaries==
Unlike most commercial software, the project release dates only apply to a release of code, not an executable program. To create a runnable program the code must be compiled, which requires several specific libraries, including some general ones and, in some cases some platform specific ones. However, since this too difficult for most mainstream users, other contributors will work to make binaries available for a specific platform and operating system. These packages vary in their stability, performance, dependencies, and how up to date they are with the code base. For example, some older binaries work on Mac OS 9 but newer releases require specific Mac OS X versions.

For example, by late 2007 the latest code release was 0.9.11-pre1 (pre-release) and 0.9.10 (final). However, the actual binaries available vary significantly. Examples of actual binaries available a year after the release of the 0.9.10 code release:

*Win-32 has ~138 Mb package (v0.9.10) (For Windows 98, 2000, ME, 32-bit XP)
*Linux- pre-built packages for specific Linux distributions
**Slackware package (v0.9.10), Fedora Core 2,3,4 packages (v0.9.10), Pardus (v0.9.10), Debian (v0.9.9)
*Solaris packages either for it running on either SPARC or x86 processors.
** SPARC (v0.9.8), x86 (v0.9.9)
*Silicon Graphics IRIX
**SGI binaries for (v0.9.9)
*Mac OS X
**Mac OS 10.4 (v0.9.10)
**Mac OS 10.3 (v0.9.9)
*FreeBSD has a package for(v0.9.10)

The release of version 1.0 marked a formal transition out of beta development since software's first release in 1997, ten years prior.

In 2008, version 1.9.0 of FlightGear switched from [[PLIB]] to [[OSG]], which caused the temporarily lost of some of the features like 3D clouds and shadows. On the other hand, new features such as particles add another degree of realism to the simulation.

To create a runnable program the code must be compiled, which requires several specific libraries, including some general ones and, in some cases some platform specific ones. However, since this too difficult for most mainstream users, other contributors will work to make binaries available for a specific platform and operating system. These packages vary in their stability, performance, dependencies, and how up to date they are with the code base. For example, some older binaries work on Mac OS 9 but newer releases require specific Mac OS X versions.

For example, by late 2007 the latest code release was 0.9.11-pre1 (pre-release) and 0.9.10 (final). However, the actual binaries available vary significantly. Examples of actual binaries available a year after the release of the 0.9.10 code release:

*Win-32 has ~138 Mb package (v0.9.10) (For Windows 98, 2000, ME, 32-bit XP)
*Linux- pre-built packages for specific Linux distributions
**Slackware package (v0.9.10), Fedora Core 2,3,4 packages (v0.9.10), Pardus (v0.9.10), Debian (v0.9.9)
*Solaris packages either for it running on either SPARC or x86 processors.
** SPARC (v0.9.8), x86 (v0.9.9)
*Silicon Graphics IRIX
**SGI binaries for (v0.9.9)
*Mac OS X
**Mac OS 10.4 (v0.9.10)
**Mac OS 10.3 (v0.9.9)
*FreeBSD has a package for(v0.9.10)

==History==
===Beginnings (1996-1997)===
Development formally started in the late-1990s with an online proposal and code being written in 1996, but using custom 3D graphics code. Development of an [[OpenGL]] based version was spearheaded by Curtis Olsen starting in 1997, after the initial start in 1996. A large community response lead to many contributing to the project from its start in late '90s up to the present.

Rather than start entirely from scratch, FlightGear developers made use of the LaRCsim flight model from NASA, with OpenGL for 3D graphic code, and freely available elevation data. First working binaries came out in 1997, with an intense updating of newer versions for several years resulting in progressively more stable and advanced programs.

===Versions 0.7–0.9 (2001–2003)===
By 2001, the team was releasing new beta versions regularly (0.7.x, 0.8.0, over 2001-2003) and with 0.9.xx (2003-2006). Later in the decade, the rate of final public releases slowed, but had larger amounts of content (0.9.10, 1.0.0 etc.). The maturity of software by 2005 lead to more widespread reviews, and increased popularity.

===Version 0.9.0-0.9.11 (2002-2007)===
The use of version numbers slowed dramatically after the late 2002 release of version 0.9.0. Versions 0.9.9 (2005) and 0.9.10 (2006) had about 8 all-new or redone [[aircraft]] adding to a total of 70-90 aircraft. FlightGear 0.9.10 won Softpedia's "Pick" award (5 out of 5 stars) on June 3, 2006 as well as the "100% CLEAN" Softpedia award.

Behind the scenes there was a 0.9.11-pre1 released in 2007 that ended up being superseded by FlightGear 1.0. The pre-version had about 33 new or redone aircraft.

[[Image:FG-A-10.jpg|thumb|270px|3D Cockpit panel for [[A-10]] in version 1.0.0 in 2008]]
===Version 1.0 (2008)===
The version number marked a formal transition out of beta development since software's first release in 1997, ten years prior.

===Version 1.9.0 (2008)===
At the time version 1.9.0 was released FlightGear switched from [[PLIB]] to [[OSG]], which caused the temporarily lost of some of the features like 3D clouds and shadows. On the contrary new features such as particles add another degree of realism to the simulation. Most aircraft developed for OSG do not work with older versions. The users is able to choose out of 230 aircraft provided with 1.9.0, altough only a few are included in the base package.

'''FlightGear Flight Simulator''' (often shortened to '''FlightGear''' or '''FGFS''') is a sophisticated free, completely open-source flight simulator framework, created by volunteers. FlightGear is released under the terms of the [[GNU General Public License]]. FlightGear is mostly written in the C++ programming language.

Increasingly detailed and realistic versions of FlightGear have been released every year since the project was started in 1996.

The latest public release is available as a free download at [http://www.flightgear.org/Downloads/ http://www.flightgear.org/Downloads/], with specific builds for a variety of operating systems including Microsoft Windows (Win 32), Mac OS X, Linux, IRIX, and Solaris.

==Software==
The simulation engine in FlightGear is called [[SimGear]]. It is used both as an end-user application and in academic and research environments, for the development and pursuit of flight simulation ideas.

This customizability of FlightGear is illustrated by the wide range of aircraft models that are available in FlightGear, from [[:Category:Gliders|glider]]s to [[Helicopter]]s, and from [[:Category:Airliners|airliners]] to [[Military aircraft|fighter jets]]. These aircraft models have been contributed by many different people.

The FlightGear aircraft use one of three main data models JSBSim, YAsim, or UIUC as of version 0.9.10. Currently only one terrain engine is used, TerraGear. Weather effects include 3D clouds, lighting effects, and time of day.

===Flight Dynamics Models===
[[Flight Dynamics Models]] (FDM) are how the flight for an aircraft is simulated in the program. FlightGear uses a variety of internally written and imported flight model projects. Any aircraft must be programmed to use one of these models. Currently FlightGear is the only flight graphical flight simulator all the FDM are used for, and UIUC and YASim were developed specifically for FlightGear.

Early version used a FDM based on [[LaRCsim]] by NASA, which was replaced with more flexible FDM.

*[[JSBSim]] - the default flight dynamics model software since 2000.
*[[YASim]] - another FDM using different calculation method. Introduced starting in 0.7.9 in 2002.
*[[UIUC]] - another included FDM, developed by the UIUC Applied Aerodynamics Group at University of Illinois at Urbana-Champaign, also made use of LaRCsim.
*Flight Gear can also be setup to render using inputs from an external FDM source, such as from Matlab.
*Other custom FDM for a specific aircraft type have been written, such as for lighter than air aircraft.

===FlightGear dependencies===
Unlike commercial software titles, the main output of the project is simply the release of a collection of code. To turn it into a usable program it must be compiled for a given platform. The software libraries used to create FlightGear have varied over time. The main one is [[SimGear]], which is the underlying sim engine for FlightGear. [[TerraGear]] is not a dependency, but simply a name for the default terrain data program in FlightGear. OpenAL is used for sound/audio software, including support for SDL (since 0.9.5). PLIB is used for hardware support routines, formerly used for sound support also which was taken over by OpenAL. [[OpenGL]] is used for its integrated 3D graphics routines, and other hardware acceleration (namely DirectX) is not supported. [[OpenSceneGraph]] is also integrated into FlightGear. Finally, Simple DirectMedia Layer is a software library which is used for compiling. Some of the dependencies vary depending on which platform the code is being compiled for. FlightGear users must either compile the code themselves, or find a third party to release a binary, if it is not among the ones available from the project.

==Hardware==
Hardware needed for FlightGear is narrow to machines that support [[OpenGL]] and 3D hardware acceleration, with NVIDIA hardware having better support. Early versions had support for 3dfx cards, though this dropped as hardware requirements increased.

[[Image:Fgrun-page2.jpg|thumb|left|270px|The [[FlightGear Launch Control|FlightGear Launcher]]]]
==Add-ons and customization==
There are programs that are either integrated into FlightGear (dependencies) or perform a function with it. Some of these are included in the release of FlightGear for a specific platform but made by the project, while others are independently distributed but are hosted by the FlightGear project.

One major additional software is the actual interface for launching an executable of FlightGear. For most of its early life FlightGear was only run through [[command line]] interfaces. However, the FlightGear Launch Control has been included with the ''[[FG launcher]]'' front-end since 0.9.3 in 2003. ''[[KFreeFlight]]'' is a launcher/front-end for KDE. ''FGTools'' is an alternative windows launcher front-end. ''FGKicker'' is a GTK+ based front-end.

Other significant programs include editors and projects for Terrain Data. ''[[Atlas]]'' is a chart/map support for FlightGear; ''[[Kelpie Flight Planner]]'' is a Java based flight planner for FlightGear. ''[[FlightGear Scenery Designer]]'' is a FlightGear scenery editor for working with terrain data. The ''[[World Custom Scenery Project]]'' is a project coordinating custom scenery efforts. Finally, ''[[TaxiDraw]]'' is an editor for airport runways and taxiways.

===Aircraft===
{{Main article|Table of models}}

FlightGear started out with an aircraft included in NASA's LaRCsim, a Navion, which was replaced by a Cessna 172 by 2000. UIUC as well as JSBsim development brought several more aircraft with them, as did the development of YASim which have since become the main FDM used in FG. As of version 1.9.0 an amount of more than 230 aircraft is provided.

[[Image:EHAM.jpg|thumb|270px|[[Boeing 737-300|Boeing 733]] docked in the [[EHAM]] scenery]]
===Scenery===
{{Main article|Scenery}}
FlightGears [[world scenery]] project contains elevation and landclass data of the enitre world. Objects -like terminals, windmills and bridges- are collected in the [[FlightGear Scenery Database|Scenery Database]].

===Networking and multi-display===
Several networking options allow FlightGear to communicate with other instances of FlightGear. A [[Multiplayer Howto|multiplayer]] protocol is available for using FlightGear on a local network in a multi aircraft environment. This could be used for formation flight or [[ATC|control tower]] simulation. Multiplayer was soon expanded to allow playing over the internet. Other features include a Google maps based moving up that allows users to observe where other players are.

Several instances of FlightGear can be synchronized to allow for a multi-monitor environment. If all instances are running at the same frame rate consistently, it is possible to get good and tight synchronization between displays.

==FlightGear code vs. binaries==
Unlike most commercial software, the project release dates only apply to a release of code, not an executable program. To create a runnable program the code must be compiled, which requires several specific libraries, including some general ones and, in some cases some platform specific ones. However, since this too difficult for most mainstream users, other contributors will work to make binaries available for a specific platform and operating system. These packages vary in their stability, performance, dependencies, and how up to date they are with the code base. For example, some older binaries work on Mac OS 9 but newer releases require specific Mac OS X versions.

For example, by late 2007 the latest code release was 0.9.11-pre1 (pre-release) and 0.9.10 (final). However, the actual binaries available vary significantly. Examples of actual binaries available a year after the release of the 0.9.10 code release:

*Win-32 has ~138 Mb package (v0.9.10) (For Windows 98, 2000, ME, 32-bit XP)
*Linux- pre-built packages for specific Linux distributions
**Slackware package (v0.9.10), Fedora Core 2,3,4 packages (v0.9.10), Pardus (v0.9.10), Debian (v0.9.9)
*Solaris packages either for it running on either SPARC or x86 processors.
** SPARC (v0.9.8), x86 (v0.9.9)
*Silicon Graphics IRIX
**SGI binaries for (v0.9.9)
*Mac OS X
**Mac OS 10.4 (v0.9.10)
**Mac OS 10.3 (v0.9.9)
*FreeBSD has a package for(v0.9.10)

By 2001, the team was releasing new beta versions regularly (0.7.x, 0.8.0, over 2001-2003) and with 0.9.xx (2003-2006). Later in the decade, the rate of final public releases slowed, but had larger amounts of content (0.9.10, 1.0.0 etc.). The maturity of software by 2005 lead to more widespread reviews, and increased popularity.

===Version 0.9.0-0.9.11 (2002-2007)===
The use of version numbers slowed dramatically after the late 2002 release of version 0.9.0. Versions 0.9.9 (2005) and 0.9.10 (2006) had about 8 all-new or redone [[aircraft]] adding to a total of 70-90 aircraft. FlightGear 0.9.10 won Softpedia's "Pick" award (5 out of 5 stars) on June 3, 2006 as well as the "100% CLEAN" Softpedia award.

Behind the scenes there was a 0.9.11-pre1 released in 2007 that ended up being superseded by FlightGear 1.0. The pre-version had about 33 new or redone aircraft.

[[Image:FG-A-10.jpg|thumb|270px|3D Cockpit panel for [[A-10]] in version 1.0.0 in 2008]]
===Version 1.0 (2008)===
The version number marked a formal transition out of beta development since software's first release in 1997, ten years prior.

===Version 1.9.0 (2008)===
At the time version 1.9.0 was released FlightGear switched from [[PLIB]] to [[OSG]], which caused the temporarily lost of some of the features like 3D clouds and shadows. On the contrary new features such as particles add another degree of realism to the simulation. Most aircraft developed for OSG do not work with older versions. The users is able to choose out of 230 aircraft provided with 1.9.0, altough only a few are included in the base package.

==Software==
The simulation engine in FlightGear is called [[SimGear]]. It is used both as an end-user application and in academic and research environments, for the development and pursuit of flight simulation ideas.

This customizability of FlightGear is illustrated by the wide range of aircraft models that are available in FlightGear, from [[:Category:Gliders|glider]]s to [[Helicopter]]s, and from [[:Category:Airliners|airliners]] to [[Military aircraft|fighter jets]]. These aircraft models have been contributed by many different people.

The FlightGear aircraft use one of three main data models JSBSim, YAsim, or UIUC as of version 0.9.10. Currently only one terrain engine is used, TerraGear. Weather effects include 3D clouds, lighting effects, and time of day.

===Flight Dynamics Models===
[[Flight Dynamics Models]] (FDM) are how the flight for an aircraft is simulated in the program. FlightGear uses a variety of internally written and imported flight model projects. Any aircraft must be programmed to use one of these models. Currently FlightGear is the only flight graphical flight simulator all the FDM are used for, and UIUC and YASim were developed specifically for FlightGear.

Early version used a FDM based on [[LaRCsim]] by NASA, which was replaced with more flexible FDM.

*[[JSBSim]] - the default flight dynamics model software since 2000.
*[[YASim]] - another FDM using different calculation method. Introduced starting in 0.7.9 in 2002.
*[[UIUC]] - another included FDM, developed by the UIUC Applied Aerodynamics Group at University of Illinois at Urbana-Champaign, also made use of LaRCsim.
*Flight Gear can also be setup to render using inputs from an external FDM source, such as from Matlab.
*Other custom FDM for a specific aircraft type have been written, such as for lighter than air aircraft.

===FlightGear dependencies===
Unlike commercial software titles, the main output of the project is simply the release of a collection of code. To turn it into a usable program it must be compiled for a given platform. The software libraries used to create FlightGear have varied over time. The main one is [[SimGear]], which is the underlying sim engine for FlightGear. [[TerraGear]] is not a dependency, but simply a name for the default terrain data program in FlightGear. OpenAL is used for sound/audio software, including support for SDL (since 0.9.5). PLIB is used for hardware support routines, formerly used for sound support also which was taken over by OpenAL. [[OpenGL]] is used for its integrated 3D graphics routines, and other hardware acceleration (namely DirectX) is not supported. [[OpenSceneGraph]] is also integrated into FlightGear. Finally, Simple DirectMedia Layer is a software library which is used for compiling. Some of the dependencies vary depending on which platform the code is being compiled for. FlightGear users must either compile the code themselves, or find a third party to release a binary, if it is not among the ones available from the project.

==Hardware==
Hardware needed for FlightGear is narrow to machines that support [[OpenGL]] and 3D hardware acceleration, with NVIDIA hardware having better support. Early versions had support for 3dfx cards, though this dropped as hardware requirements increased.

[[Image:Fgrun-page2.jpg|thumb|left|270px|The [[FlightGear Launch Control|FlightGear Launcher]]]]
==Add-ons and customization==
There are programs that are either integrated into FlightGear (dependencies) or perform a function with it. Some of these are included in the release of FlightGear for a specific platform but made by the project, while others are independently distributed but are hosted by the FlightGear project.

One major additional software is the actual interface for launching an executable of FlightGear. For most of its early life FlightGear was only run through [[command line]] interfaces. However, the FlightGear Launch Control has been included with the ''[[FG launcher]]'' front-end since 0.9.3 in 2003. ''[[KFreeFlight]]'' is a launcher/front-end for KDE. ''FGTools'' is an alternative windows launcher front-end. ''FGKicker'' is a GTK+ based front-end.

Other significant programs include editors and projects for Terrain Data. ''[[Atlas]]'' is a chart/map support for FlightGear; ''[[Kelpie Flight Planner]]'' is a Java based flight planner for FlightGear. ''[[FlightGear Scenery Designer]]'' is a FlightGear scenery editor for working with terrain data. The ''[[World Custom Scenery Project]]'' is a project coordinating custom scenery efforts. Finally, ''[[TaxiDraw]]'' is an editor for airport runways and taxiways.

===Aircraft===
{{Main article|Table of models}}

FlightGear started out with an aircraft included in NASA's LaRCsim, a Navion, which was replaced by a Cessna 172 by 2000. UIUC as well as JSBsim development brought several more aircraft with them, as did the development of YASim which have since become the main FDM used in FG. As of version 1.9.0 an amount of more than 230 aircraft is provided.

[[Image:EHAM.jpg|thumb|270px|[[Boeing 737-300|Boeing 733]] docked in the [[EHAM]] scenery]]
===Scenery===
{{Main article|Scenery}}
FlightGears [[world scenery]] project contains elevation and landclass data of the enitre world. Objects -like terminals, windmills and bridges- are collected in the [[FlightGear Scenery Database|Scenery Database]].

===Networking and multi-display===
Several networking options allow FlightGear to communicate with other instances of FlightGear. A [[Multiplayer Howto|multiplayer]] protocol is available for using FlightGear on a local network in a multi aircraft environment. This could be used for formation flight or [[ATC|control tower]] simulation. Multiplayer was soon expanded to allow playing over the internet. Other features include a Google maps based moving up that allows users to observe where other players are.

Several instances of FlightGear can be synchronized to allow for a multi-monitor environment. If all instances are running at the same frame rate consistently, it is possible to get good and tight synchronization between displays.

==FlightGear code vs. binaries==
Unlike most commercial software, the project release dates only apply to a release of code, not an executable program. To create a runnable program the code must be compiled, which requires several specific libraries, including some general ones and, in some cases some platform specific ones. However, since this too difficult for most mainstream users, other contributors will work to make binaries available for a specific platform and operating system. These packages vary in their stability, performance, dependencies, and how up to date they are with the code base. For example, some older binaries work on Mac OS 9 but newer releases require specific Mac OS X versions.

For example, by late 2007 the latest code release was 0.9.11-pre1 (pre-release) and 0.9.10 (final). However, the actual binaries available vary significantly. Examples of actual binaries available a year after the release of the 0.9.10 code release:

*Win-32 has ~138 Mb package (v0.9.10) (For Windows 98, 2000, ME, 32-bit XP)
*Linux- pre-built packages for specific Linux distributions
**Slackware package (v0.9.10), Fedora Core 2,3,4 packages (v0.9.10), Pardus (v0.9.10), Debian (v0.9.9)
*Solaris packages either for it running on either SPARC or x86 processors.
** SPARC (v0.9.8), x86 (v0.9.9)
*Silicon Graphics IRIX
**SGI binaries for (v0.9.9)
*Mac OS X
**Mac OS 10.4 (v0.9.10)
**Mac OS 10.3 (v0.9.9)
*FreeBSD has a package for(v0.9.10)

'''FlightGear Flight Simulator''' (often shortened to '''FlightGear''' or '''FGFS''') is a sophisticated free, completely open-source flight simulator framework, created by volunteers. FlightGear is released under the terms of the [[GNU General Public License]]. FlightGear is mostly written in C++ with some in C programming languages.

Increasingly detailed and realistic versions of FlightGear have been released every year since the project was started in 1996.

The latest public release is available as a free download at [http://www.flightgear.org/Downloads/ http://www.flightgear.org/Downloads/], with specific builds for a variety of operating systems including Microsoft Windows (Win 32), Mac OS X, Linux, IRIX, and Solaris.

==History==
===Beginnings (1996-1997)===
Development formally started in the late-1990s with an online proposal and code being written in 1996, but using custom 3D graphics code. Development of an [[OpenGL]] based version was spearheaded by Curtis Olsen starting in 1997, after the initial start in 1996. A large community response lead to many contributing to the project from its start in late '90s up to the present.

Rather than start entirely from scratch, FlightGear developers made use of the LaRCsim flight model from NASA, with OpenGL for 3D graphic code, and freely available elevation data. First working binaries came out in 1997, with an intense updating of newer versions for several years resulting in progressively more stable and advanced programs.

===Versions 0.7–0.9 (2001–2003)===
By 2001, the team was releasing new beta versions regularly (0.7.x, 0.8.0, over 2001-2003) and with 0.9.xx (2003-2006). Later in the decade, the rate of final public releases slowed, but had larger amounts of content (0.9.10, 1.0.0 etc.). The maturity of software by 2005 lead to more widespread reviews, and increased popularity.

===Version 0.9.0-0.9.11 (2002-2007)===
The use of version numbers slowed dramatically after the late 2002 release of version 0.9.0. Versions 0.9.9 (2005) and 0.9.10 (2006) had about 8 all-new or redone [[aircraft]] adding to a total of 70-90 aircraft. FlightGear 0.9.10 won Softpedia's "Pick" award (5 out of 5 stars) on June 3, 2006 as well as the "100% CLEAN" Softpedia award.

Behind the scenes there was a 0.9.11-pre1 released in 2007 that ended up being superseded by FlightGear 1.0. The pre-version had about 33 new or redone aircraft.

[[Image:FG-A-10.jpg|thumb|270px|3D Cockpit panel for [[A-10]] in version 1.0.0 in 2008]]
===Version 1.0 (2008)===
The version number marked a formal transition out of beta development since software's first release in 1997, ten years prior.

===Version 1.9.0 (2008)===
At the time version 1.9.0 was released FlightGear switched from [[PLIB]] to [[OSG]], which caused the temporarily lost of some of the features like 3D clouds and shadows. On the contrary new features such as particles add another degree of realism to the simulation. Most aircraft developed for OSG do not work with older versions. The users is able to choose out of 230 aircraft provided with 1.9.0, altough only a few are included in the base package.

However, since this too difficult for most mainstream users, other contributors will work to make binaries available for a specific platform and operating system. These packages vary in their stability, performance, dependencies, and how up to date they are with the code base. For example, some older binaries work on Mac OS 9 but newer releases require specific Mac OS X versions.

For example, by late 2007 the latest code release was 0.9.11-pre1 (pre-release) and 0.9.10 (final). However, the actual binaries available vary significantly. Examples of actual binaries available a year after the release of the 0.9.10 code release:

*Win-32 has ~138 Mb package (v0.9.10) (For Windows 98, 2000, ME, 32-bit XP)
*Linux- pre-built packages for specific Linux distributions
**Slackware package (v0.9.10), Fedora Core 2,3,4 packages (v0.9.10), Pardus (v0.9.10), Debian (v0.9.9)
*Solaris packages either for it running on either SPARC or x86 processors.
** SPARC (v0.9.8), x86 (v0.9.9)
*Silicon Graphics IRIX
**SGI binaries for (v0.9.9)
*Mac OS X
**Mac OS 10.4 (v0.9.10)
**Mac OS 10.3 (v0.9.9)
*FreeBSD has a package for(v0.9.10)

'''FlightGear Flight Simulator''' (often shortened to '''FlightGear''' or '''FGFS''') is a sophisticated free, completely open-source flight simulator framework, created by volunteers.

The project was started back in 1996, with the first release in 1997. The latest public release is 1.9.1 in December 2008, with specific builds for a variety of operating systems including Microsoft Windows (Win 32), Mac OS X, Linux, IRIX, and Solaris.

FlightGear is released under the terms of the [[GNU General Public License]]. Flightgear is mostly written in C++ with some in C programming languages.

==History==
===Beginnings (1996-1997)===
Development formally started in the late-1990s with an online proposal and code being written in 1996, but using custom 3D graphics code. Development of an [[OpenGL]] based version was spearheaded by Curtis Olsen starting in 1997, after the initial start in 1996. A large community response lead to many contributing to the project from its start in late '90s up to the present.

Rather than start entirely from scratch, FlightGear developers made use of the LaRCsim flight model from NASA, with OpenGL for 3D graphic code, and freely available elevation data. First working binaries came out in 1997, with an intense updating of newer versions for several years resulting in progressively more stable and advanced programs.

===Versions 0.7–0.9 (2001–2003)===
By 2001, the team was releasing new beta versions regularly (0.7.x, 0.8.0, over 2001-2003) and with 0.9.xx (2003-2006). Later in the decade, the rate of final public releases slowed, but had larger amounts of content (0.9.10, 1.0.0 etc.). The maturity of software by 2005 lead to more widespread reviews, and increased popularity.

===Version 0.9.0-0.9.11 (2002-2007)===
The use of version numbers slowed dramatically after the late 2002 release of version 0.9.0. Versions 0.9.9 (2005) and 0.9.10 (2006) had about 8 all-new or redone [[aircraft]] adding to a total of 70-90 aircraft. FlightGear 0.9.10 won Softpedia's "Pick" award (5 out of 5 stars) on June 3, 2006 as well as the "100% CLEAN" Softpedia award.

Behind the scenes there was a 0.9.11-pre1 released in 2007 that ended up being superseded by FlightGear 1.0. The pre-version had about 33 new or redone aircraft.

[[Image:FG-A-10.jpg|thumb|270px|3D Cockpit panel for [[A-10]] in version 1.0.0 in 2008]]
===Version 1.0 (2008)===
The version number marked a formal transition out of beta development since software's first release in 1997, ten years prior.

===Version 1.9.0 (2008)===
At the time version 1.9.0 was released FlightGear switched from [[PLIB]] to [[OSG]], which caused the temporarily lost of some of the features like 3D clouds and shadows. On the contrary new features such as particles add another degree of realism to the simulation. Most aircraft developed for OSG do not work with older versions. The users is able to choose out of 230 aircraft provided with 1.9.0, altough only a few are included in the base package.

==Software==
The simulation engine in FlightGear is called [[SimGear]]. It is used both as an end-user application and in academic and research environments, for the development and pursuit of flight simulation ideas.

This customizability of FlightGear is illustrated by the wide range of aircraft models that are available in FlightGear, from [[:Category:Gliders|glider]]s to [[Helicopter]]s, and from [[:Category:Airliners|airliners]] to [[Military aircraft|fighter jets]]. These aircraft models have been contributed by many different people.

The FlightGear aircraft use one of three main data models JSBSim, YAsim, or UIUC as of version 0.9.10. Currently only one terrain engine is used, TerraGear. Weather effects include 3D clouds, lighting effects, and time of day.

===Flight Dynamics Models===
[[Flight Dynamics Models]] (FDM) are how the flight for an aircraft is simulated in the program. FlightGear uses a variety of internally written and imported flight model projects. Any aircraft must be programmed to use one of these models. Currently FlightGear is the only flight graphical flight simulator all the FDM are used for, and UIUC and YASim were developed specifically for FlightGear.

Early version used a FDM based on [[LaRCsim]] by NASA, which was replaced with more flexible FDM.

*[[JSBSim]] - the default flight dynamics model software since 2000.
*[[YASim]] - another FDM using different calculation method. Introduced starting in 0.7.9 in 2002.
*[[UIUC]] - another included FDM, developed by the UIUC Applied Aerodynamics Group at University of Illinois at Urbana-Champaign, also made use of LaRCsim.
*Flight Gear can also be setup to render using inputs from an external FDM source, such as from Matlab.
*Other custom FDM for a specific aircraft type have been written, such as for lighter than air aircraft.

===FlightGear dependencies===
Unlike commercial software titles, the main output of the project is simply the release of a collection of code. To turn it into a usable program it must be compiled for a given platform. The software libraries used to create FlightGear have varied over time. The main one is [[SimGear]], which is the underlying sim engine for FlightGear. [[TerraGear]] is not a dependency, but simply a name for the default terrain data program in FlightGear. OpenAL is used for sound/audio software, including support for SDL (since 0.9.5). PLIB is used for hardware support routines, formerly used for sound support also which was taken over by OpenAL. [[OpenGL]] is used for its integrated 3D graphics routines, and other hardware acceleration (namely DirectX) is not supported. [[OpenSceneGraph]] is also integrated into FlightGear. Finally, Simple DirectMedia Layer is a software library which is used for compiling. Some of the dependencies vary depending on which platform the code is being compiled for. FlightGear users must either compile the code themselves, or find a third party to release a binary, if it is not among the ones available from the project.

==Hardware==
Hardware needed for FlightGear is narrow to machines that support [[OpenGL]] and 3D hardware acceleration, with NVIDIA hardware having better support. Early versions had support for 3dfx cards, though this dropped as hardware requirements increased.

[[Image:Fgrun-page2.jpg|thumb|left|270px|The [[FlightGear Launch Control|FlightGear Launcher]]]]
==Add-ons and customization==
There are programs that are either integrated into FlightGear (dependencies) or perform a function with it. Some of these are included in the release of FlightGear for a specific platform but made by the project, while others are independently distributed but are hosted by the FlightGear project.

One major additional software is the actual interface for launching an executable of FlightGear. For most of its early life FlightGear was only run through [[command line]] interfaces. However, the FlightGear Launch Control has been included with the ''[[FG launcher]]'' front-end since 0.9.3 in 2003. ''[[KFreeFlight]]'' is a launcher/front-end for KDE. ''FGTools'' is an alternative windows launcher front-end. ''FGKicker'' is a GTK+ based front-end.

Other significant programs include editors and projects for Terrain Data. ''[[Atlas]]'' is a chart/map support for FlightGear; ''[[Kelpie Flight Planner]]'' is a Java based flight planner for FlightGear. ''[[FlightGear Scenery Designer]]'' is a FlightGear scenery editor for working with terrain data. The ''[[World Custom Scenery Project]]'' is a project coordinating custom scenery efforts. Finally, ''[[TaxiDraw]]'' is an editor for airport runways and taxiways.

===Aircraft===
{{Main article|Table of models}}

FlightGear started out with an aircraft included in NASA's LaRCsim, a Navion, which was replaced by a Cessna 172 by 2000. UIUC as well as JSBsim development brought several more aircraft with them, as did the development of YASim which have since become the main FDM used in FG. As of version 1.9.0 an amount of more than 230 aircraft is provided.

[[Image:EHAM.jpg|thumb|270px|[[Boeing 737-300|Boeing 733]] docked in the [[EHAM]] scenery]]
===Scenery===
{{Main article|Scenery}}
FlightGears [[world scenery]] project contains elevation and landclass data of the enitre world. Objects -like terminals, windmills and bridges- are collected in the [[FlightGear Scenery Database|Scenery Database]].

===Networking and multi-display===
Several networking options allow FlightGear to communicate with other instances of FlightGear. A [[Multiplayer Howto|multiplayer]] protocol is available for using FlightGear on a local network in a multi aircraft environment. This could be used for formation flight or [[ATC|control tower]] simulation. Multiplayer was soon expanded to allow playing over the internet. Other features include a Google maps based moving up that allows users to observe where other players are.

Several instances of FlightGear can be synchronized to allow for a multi-monitor environment. If all instances are running at the same frame rate consistently, it is possible to get good and tight synchronization between displays.

==FlightGear code vs. binaries==
Unlike most commercial software, the project release dates only apply to a release of code, not an executable program. To create a runnable program the code must be compiled, which requires several specific libraries, including some general ones and, in some cases some platform specific ones. However, since this too difficult for most mainstream users, other contributors will work to make binaries available for a specific platform and operating system. These packages vary in their stability, performance, dependencies, and how up to date they are with the code base. For example, some older binaries work on Mac OS 9 but newer releases require specific Mac OS X versions.

For example, by late 2007 the latest code release was 0.9.11-pre1 (pre-release) and 0.9.10 (final). However, the actual binaries available vary significantly. Examples of actual binaries available a year after the release of the 0.9.10 code release:

*Win-32 has ~138 Mb package (v0.9.10) (For Windows 98, 2000, ME, 32-bit XP)
*Linux- pre-built packages for specific Linux distributions
**Slackware package (v0.9.10), Fedora Core 2,3,4 packages (v0.9.10), Pardus (v0.9.10), Debian (v0.9.9)
*Solaris packages either for it running on either SPARC or x86 processors.
** SPARC (v0.9.8), x86 (v0.9.9)
*Silicon Graphics IRIX
**SGI binaries for (v0.9.9)
*Mac OS X
**Mac OS 10.4 (v0.9.10)
**Mac OS 10.3 (v0.9.9)
*FreeBSD has a package for(v0.9.10)

Updating FlightGear on Windows

2010-01-20T17:15:16Z

Michaelfavor: /* Update your FlightGear Data using CVS */ copy edit

Some FlightGear users may want to test the latest version currently being developed, before the next stable release version is available as a regular download. Although getting the latest development version of FlightGear usually requires a complicated process of compiling source files (See [[Building FlightGear]]), there is a much easier way to get almost-the-latest development version, by downloading updated data files from the [[FlightGear CVS]], and combining them with a pre-compiled binary executable.

New versions of the FlightGear development branch are available as pre-compiled binaries for Windows. These binaries are compiled from recent snapshots of the [[CVS]] version of the source code files. Combining these pre-compiled binaries along with the current FlightGear "data" from CVS makes it much easier and faster for users to try out very current versions of FlightGear. A big “thank you” to the developers for providing this service.

The following steps make it easy to keep up with the latest developments in FlightGear:

==Download an Updated Windows Binary==

Updated windows binaries are available for download from several FlightGear generous developers listed below. Every binary version is slightly different, based on the date it was built from CVS. Check the file-name to find the latest version.

*[http://blaniel.free.fr/pub/flightgear/snapshots/ Pre-compiled FlightGear executables by Benoit Laniel], look for files like [http://blaniel.free.fr/pub/flightgear/snapshots/fgfs_win32_20100118.7z fgfs_win32_20100118.7z] (Jan 2010)
*[ftp://ftp.abbeytheatre2.org.uk/fgfs/executable/ Pre-compiled FlightGear executables by Vivian Meazza], look for files like [ftp://ftp.abbeytheatre2.org.uk/fgfs/executable/fgfs-20100104.zip fgfs-20100104.zip] (Jan 2010)
*[ftp://ftp.ihg.uni-duisburg.de/FlightGear/Win32/ Pre-compiled FlightGear executables by Frederic Bouvier], look for files like update [ftp://ftp.ihg.uni-duisburg.de/FlightGear/Win32/fgrun+fgfs-osg-win32-cvs-20100117.zip fgrun+fgfs-osg-win32-cvs-20100117.zip] (Jan 2010)

After downloading, unzip the update into your C:\FlightGear\bin\Win32\ folder (or equivalent).

==Update your FlightGear Data using CVS==

An updated version of the FlightGear executable works best with a current version of the FlightGear data from CVS (the base package). This is not only to get the newest developments but also because configuration files or data formats might have changed. And, an older version of the FlightGear executable program (fgfs.exe) may not be compatible with a more recent version of the base data package. Make sure your executable version matches your data version before reporting bugs.

You have to download the newest data from the FlightGear data CVS repository using a CVS client. If you don't have CVS client software already, download and install TortoiseCVS or WinCVS:
* [[Using TortoiseCVS with FlightGear]].
* [[Using WinCVS with FlightGear]]

The following instructions assume you are using TortoiseCVS, but the process for using WinCVS is very similar.

The initial checkout from CVS is a lot of data (about 2 GB) so it helps if you have a fast internet connection.

First go to your desired directory and Creae a folder named '''Flightgear'''.Now Right click the folder and you will see a menu as follows

[[Image:CVS-Checkout.JPG]]

Click on CVS Checkout. Fill the '''CVS ROOT''' with
:pserver:cvsguest@cvs.flightgear.org:/var/cvs/FlightGear-0.9

'''User name''' with cvsguest

'''Module''' with data

You Should have something like this :

[[Image:CVS.JPG]]

4: Just Click OK. If you are Prompted for Password Enter
guest
You should have something running on like this :
[[Image:CVS-2.JPG]]

5: If you cant keep your PC on for long time till the process completes, you can abort it and then the next time you start just right click the '''data''' folder inside the '''Flightgear''' folder. And click '''CVS Update'''

[[Image:CVS-Update.JPG]]

6: '''Now for the Binaries'''

This is even more Simple. First Go to your Old '''Flightgear 1.0''' folder and copy the '''bin''' directory.
Then Paste it in the new '''Flightgear''' folder

Note: If you dont have the old files, please request at the [http://www.flightgear.org/forums/ forums], and i or someone else will upload them.

7: Now go to the binaries download page -[ftp://ftp.ihg.uni-duisburg.de/FlightGear/Win32/ Binary Page]

Get the latest file with the prefix '''fgrun+fgfs-osg-win32-''' and extract that into '''Flightgear/bin/win32'''

When starting fgrun.exe from that location, click "back" and make sure that the program and FG_root directories are set to the '''new''' location. You can use the scenery from the old location (as in the example below).

[[Image:CVS-changepath.png]]

8: Repeat steps '''5''' and '''7''' regularly to keep updating.

'''Note: "Keep your CVS-data up to the binaries date" AND "DO NOT REPORT BUGS UNLESS YOUR PROGRAM AND DATA MATCH!
"'''

==Checking out an older version of a file or folder==

Sometimes you may wish to get an older version of a file than is at CVS head. As a made up example, let's say you just updated your source code from CVS head and now you get errors when you try to compile. You decide that a single file has been changed and the new version is causing your compile errors. You can get any previous version of that file (or any other file) from the CVS repository.

In Windows explorer, right-click on the file or folder that you want update from a certain date. From the pop-up menu, choose "CVS >" and then "Update special..." Check the "Get time/date" checkbox, select the desired date from the calendar shown and click the "OK" button to begin the checkout.

All the steps described above are easy if you have read this document carefully.
Have fun with FlightGear!

You decide that a single file has been changed and the new version is causing your compile errors. You can get any previous version of that file (or any other file) from the CVS repository.

In Windows explorer, right-click on the file or folder that you want update from a certain date. From the pop-up menu, choose "CVS >" and then "Update special..." Check the "Get time/date" checkbox, select the desired date from the calendar shown and click the "OK" button to begin the checkout.

Updating FlightGear on Windows

2010-01-20T16:35:02Z

Michaelfavor: /* Download an Updated Windows Binary */ added example links

Some FlightGear users may want to test the latest version currently being developed, before the next stable release version is available as a regular download. Although getting the latest development version of FlightGear usually requires a complicated process of compiling source files (See [[Building FlightGear]]), there is a much easier way to get almost-the-latest development version, by downloading updated data files from the [[FlightGear CVS]], and combining them with a pre-compiled binary executable.

The following steps make it easy to keep up with the latest developments in FlightGear:

==Download an Updated Windows Binary==

New versions of the FlightGear development branch are available as pre-compiled binaries for Windows. These binaries are compiled from recent snapshots of the [[CVS]] version of the source code files. A big “thank you” to the developers for providing this service as a convenience.

Check the file-name to find the latest version.

*[http://blaniel.free.fr/pub/flightgear/snapshots/ Pre-compiled FlightGear executables by Benoit Laniel], look for files like [http://blaniel.free.fr/pub/flightgear/snapshots/fgfs_win32_20100118.7z fgfs_win32_20100118.7z] (Jan 2010)
*[ftp://ftp.abbeytheatre2.org.uk/fgfs/executable/ Pre-compiled FlightGear executables by Vivian Meazza], look for files like [ftp://ftp.abbeytheatre2.org.uk/fgfs/executable/fgfs-20100104.zip fgfs-20100104.zip] (Jan 2010)
*[ftp://ftp.ihg.uni-duisburg.de/FlightGear/Win32/ Pre-compiled FlightGear executables by Frederic Bouvier], look for files like update [ftp://ftp.ihg.uni-duisburg.de/FlightGear/Win32/fgrun+fgfs-osg-win32-cvs-20100117.zip fgrun+fgfs-osg-win32-cvs-20100117.zip] (Jan 2010)

==Update your FlightGear Data using CVS==
New development versions of the executable FlightGear program require a matching version of the FlightGear data (the base package) not only to get the newest developments but also because configuration files or data formats might have changed. And, an older version of the FlightGear executable program (fgfs.exe) may not be compatible with a more recent version of the base data package. Make sure your executable version matches your data version before reporting bugs.

You have to download the newest data from the FlightGear data CVS repository using a CVS client. If you don't have CVS client software already, download and install TortoiseCVS or WinCVS:
* [[Using TortoiseCVS with FlightGear]].
* [[Using WinCVS with FlightGear]]

The following instructions assume you are using TortoiseCVS, but the process for using WinCVS is very similar.

The initial checkout from CVS is a lot of data (about 2 GB) so it helps if you have a fast internet connection.

First go to your desired directory and Creae a folder named '''Flightgear'''.Now Right click the folder and you will see a menu as follows

[[Image:CVS-Checkout.JPG]]

Click on CVS Checkout. Fill the '''CVS ROOT''' with
:pserver:cvsguest@cvs.flightgear.org:/var/cvs/FlightGear-0.9

'''User name''' with cvsguest

'''Module''' with data

You Should have something like this :

[[Image:CVS.JPG]]

4: Just Click OK. If you are Prompted for Password Enter
guest
You should have something running on like this :
[[Image:CVS-2.JPG]]

5: If you cant keep your PC on for long time till the process completes, you can abort it and then the next time you start just right click the '''data''' folder inside the '''Flightgear''' folder. And click '''CVS Update'''

[[Image:CVS-Update.JPG]]

6: '''Now for the Binaries'''

This is even more Simple. First Go to your Old '''Flightgear 1.0''' folder and copy the '''bin''' directory.
Then Paste it in the new '''Flightgear''' folder

Note: If you dont have the old files, please request at the [http://www.flightgear.org/forums/ forums], and i or someone else will upload them.

7: Now go to the binaries download page -[ftp://ftp.ihg.uni-duisburg.de/FlightGear/Win32/ Binary Page]

Get the latest file with the prefix '''fgrun+fgfs-osg-win32-''' and extract that into '''Flightgear/bin/win32'''

When starting fgrun.exe from that location, click "back" and make sure that the program and FG_root directories are set to the '''new''' location. You can use the scenery from the old location (as in the example below).

[[Image:CVS-changepath.png]]

8: Repeat steps '''5''' and '''7''' regularly to keep updating.

'''Note: "Keep your CVS-data up to the binaries date" AND "DO NOT REPORT BUGS UNLESS YOUR PROGRAM AND DATA MATCH!
"'''

==Checking out an older version of a file or folder==

Sometimes you may wish to get an older version of a file than is at CVS head. As a made up example, let's say you just updated your source code from CVS head and now you get errors when you try to compile. You decide that a single file has been changed and the new version is causing your compile errors. You can get any previous version of that file (or any other file) from the CVS repository.

In Windows explorer, right-click on the file or folder that you want update from a certain date. From the pop-up menu, choose "CVS >" and then "Update special..." Check the "Get time/date" checkbox, select the desired date from the calendar shown and click the "OK" button to begin the checkout.

KLN89

Michaelfavor: new page

A KLN89b GPS instrument, based on code committed by Dave Luff, worked in FlightGear version 0.9 or 1.0

There is no clear reason why the KLN89 doesn't appear in the current version of the C172.

Fixing some (hopefully minor) issues may get it to work as originally designed.
