The FG1000 is a simulation of the Garmin G1000 glass panel flight deck.  The FG1000 was developed in reference to the pilot's manual for the Cessna NAVIII variant, as fitted to the Cessna 182, but is designed to be flexible and also work with other airframes.  For detailed instructions on how to use it, refer to the [https://static.garmin.com/pumac/G1000:CessnaNavIII_PilotsGuide_SystemSoftwareVersion0563.11orlater_.pdf Garmin Pilot's Guide].  Or read the Cheat's guide below.

== A Cheat's Guide to Using the FG1000 ==
 
For those without the time or interest to read the G1000 User Guide, here's a very quick run-down on navigating through the MFD:
 
General:
* Click on the buttons, though some are not implemented yet.
* Use the mouse wheel to scroll the knobs (NAV, HDG, ALT, COM, CRS/BARO, RANGE, FMS).  For knobs with both and inner and an outer (NAV, COM, CRS/BARO, FMS), scrolling when pressing the Shift key changes the outer knob.
* Use the outer FMS knob (shift-mouse wheel on the FMS knob on the bottom right) to navigate through the page groups.
* Use the inner FMS knob (mouse wheel on the FMS knob on the bottom right) to navigate through the pages within the group.  The currently selected page is shown in blue. If you stop moving the cursor, the page will be loaded in 0.5s.
* Within a page, click on the FMS knob to activate the cursor (CRSR).  You you should see some element highlighted on the page, typically flashing.  You can navigate around the page using the outer and inner FMS knobs.  The Outer FMS knob (shift-mouse wheel) typical moves the cursor between elements.  The Inner FMS knob typically changes the selected item.
* Use the RANGE knob to zoom map views in/out.
 
===PFD===
* Artificial horizon, compass rose, altimeter and airspeed indicator are all hopefully obvious!
* HSI can display NAV1, NAV2, GPS information (press the CDI softkey)
* Wind information (press PFD->WIND then select one of the options for display)
* Bearings to NAV1, NAV2, GPS (press PFD then BRG1/BRG2 to cycle through the options)
* Inset Map (Press INSET softkey)
* Active Flight Plan (press FPL when there is an active flightplan to display)
* DirectTo GPS (press DTO)
* Transponder (press XPDR)
* NRST scrolls through information on the 10 nearest airports (press NRST)
 
===MFD===
* There is a two channel NAV/COM with an active and standby frequency and automatic ID of NAV frequencies at the top of the UI.  They all integrate with the standard properties, so should work automatically with most aircraft.
* If you have a frequency highlighted in any of the pages (e.g. WPT - AIRPORT INFORMATION) press the ENT key to load it into the standby NAV/COM frequency as appropriate.
* To set up a GPS Direct To route:
** Press the DTO button (D with an arrow through it on the right side of the panel, below the word "PAN").  This will bring up a Direct To window, allowing you to enter the ID of an airport, Fix etc. to navigate to.
** You can enter the ID in one of three ways:
*** Scroll the FMS knob backwards to bring up a sub-menu of waypoints categories (FPL, NRST, RECENT, USER, AIRWAY).  Use the inner FMS knob to scroll between the different categories, and the outer FMS knob to select a specific item. 
*** Scroll the FMS knob forwards to enter an ID manually using the FMS knob.  Use the outer FMS knob to move to the next poisition in the ID.
*** Use multikey support to type in the ID using the keyboard - type ":ms" followed by the ID.  This is by far the fastest method!
** Once you've got an ID, press ENT which will load details into the window and highlight the ACTIVATE button.
** Press ENT once more to load the Direct-to into the GPS and activate it.
* To view airport information, select the WPT - AIRPORT INFORMATION page.  Use the outer FMS knob to move between the AIRPORT, RUNWAYS and FREQUENCY boxes, and the inner FMS to edit the airport ID, scroll through available runways, or highlight a frequency.
* To edit the current flightplan, press the FPL page, then press the CRSR and enter waypoints for DTO above.
 
 
===GFC700 Autopilot===
The GFC700 autopilot is a two axis autopilot with independent lateral and vertical modes.  The default later/vertical modes are ROL and PIT, which hold the current roll and pitch respectively.
If installed on the aircraft, the GFC700 autopilot is enabled by pressing any of the buttons on the bottom left of the PFD/MFD fascia:
* AP enables/disables autopilot
* FD enables a Flight Director mode, displaying control bars to follow manually.  Note that this button is disabled when the autopilot is enabled.
* HDG enables a heading mode, tracking the blue heading bug.  Use the HDG knob on the PFD to set.
* VS enables Vertical Speed hold.  Current target is displayed at the top of the PFD.  It may be adjusted by using NOSE UP / NOSE DN.
* ALT enables Altitude Hold, which holds the current altitude.
* GA enables Go Around, which sets ROL to 0 and PIT to 7 degrees nose up.
* NAV enables NAV mode.  The navigation source depends on what the CDI is set to on the PFD.  Currently this is only implemented for GPS.
* APR enables Approach mode for both vertical and lateral GPS or ILS approaches.  Will use the currently selected CDI source.
* VNV enables vertical NAV mode (not yet implemented)
* FLC enables Flight Level Change, where the autopilot will maintain the current airspeed by pitch.  NOSE UP / NOSE DN is used to set the target airspeed, which is displayed at the top of the PFD, and on the airspeed tape.
* BC enables Back Course mode (not yet implemented)
 
 
Buttons toggle modes on/off, defaulting to ROL for lateral and PIT for vertical.  The current pitch setting in PIT mode can be adjusted by using the NOSE UP and NOSE DN buttons.
 
In PIT/VS/FLC mode, Selected Altitude Capture mode (ALTS) is armed, targetting the current altitude bug.  Once the aircraft gets within 200ft of the selected altitude the autopilot will automatically transition to ALTS and then ALT mode to track that altitude.  Note that once the altitude is fixed in ALTS mode changing the altitude bug will not change the target altitude.
 
(Control Wheel Steering (CWS) can be used to set new ROL/PIT targets, but is not yet implemented)
 
===Multikey Support===
 
To improve usability, the FG1000 also supports multikey.  If installed on the aircraft (aircraft developers need to include Aircraft/Instruments-3d/FG1000/fg1000-multikey.xml), the following keys are available.
 
* ":p" controls the PFD
** 1- 12 selects the softkeys
** s allows you to use the keyboard to enter text directly into the PFD, e.g. when entering an airport
* ":m" controls the MFD
** 1-12 selects the softkeys
** a selects the Airport Information page
** c selects the Checklists page
** f selects the Flightplan page
** m selects the Navigation Map page
** n selects the Nearest Airports page
** s allows you to use the keyboard to enter text directly into the PFD, e.g. when entering an airport
** t selects the Traffic Map page
 
== Aircraft Installation ==
 
Adding the FG1000 to an aircraft is intended to be fairly straightforward, but there is a little complexity due to properties that different aircraft use, and the Engine Information System (EIS) needing to be different for different powerplants.  The J3Cub is a good example to use to see how the FG1000 integration can be done (the c182t isn't a good example as it uses the default FG1000 implementation).
 
=== Add the GDU to the cockpit ===
 
Place one or more of the display (GDU) units in your model.  The XML files
are in GDU104X directory and are named  <model>.<device-number>.xml, e.g.
 
GDU-1045.1.xml  GDU-1045.2.xml  GDU-1045.3.xml  GDU-1045.4.xml
 
The <device-number> is referenced later to identify which displays to used
for each PFD, MFD etc.  You must only used one of each <device-number> value,
though you can mix and match the GDU models.
 
The different GDU models are as follows:
 
* GDU-1040 - No autopilot controls
* GDU-1044B - autopilot controls without VNAV
* GDU-1045 - autopilot controls with VNAV
 
=== Include the GFC700 autopilot (optional)===
 
If using the 1044B or 1045 GDU, the GFC700 autopilot can be incorporated by adding the following to under /sim/systems
<syntaxhighlight lang="xml">
<autopilot>
      <path>Aircraft/Instruments-3d/FG1000/GFC700.xml</path>
</autopilot>
</syntaxhighlight>
 
The autopilot has been tuned for the Cessna 182, so may not be correct for light jets.
 
=== Load the Interfaces to provide data ===
 
This is used to provide airdata, navdata, NAV/COM settings, engine information
to the GDUs. There is a
generic interface (GenericInterfaceController) that uses the standard FG route
manager, GPS, navigation data and NAV/COM settings, and engine data for a single
piston engine.
 
You need to load it as follows:
 
<syntaxhighlight lang="nasal">
var nasal_dir = getprop("/sim/fg-root") ~ "/Aircraft/Instruments-3d/FG1000/Nasal/";
io.load_nasal(nasal_dir ~ 'Interfaces/GenericInterfaceController.nas', "fg1000");
 
var interfaceController = fg1000.GenericInterfaceController.getOrCreateInstance();
interfaceController.start();
</syntaxhighlight>
 
You may want to create your own version depending on what properties you are
using for the NAV/COM, and your engine configuration.  In which case you should
copy /Aircraft/Instruments-3d/FG1000/Nasal/Interfaces/GenericInterfaceController.nas
into your aircraft Nasal directory, edit it to load any updated interfaces and
load it instead:
 
<syntaxhighlight lang="nasal">
var aircraft_dir = getprop("/sim/aircraft-dir");
io.load_nasal(aircraft_dir ~ '/Nasal/GenericInterfaceController.nas', "fg1000");
 
var interfaceController = fg1000.GenericInterfaceController.getOrCreateInstance();
interfaceController.start();
</syntaxhighlight>
 
Note that you should only start the interface after you've started the FG1000
as they will publish information at start of day that the displays need.
 
=== Create an EIS Display ===
 
This is the Engine Information System and displays on the left side of the MFD. 
 
A simply EIS for the Cessna 182T is provided.  For other aircraft you will need to create your own.  The simplest way to do this is
 
# Copy Aircraft/Instruments-3d/FG1000/EIS into your aircraft Nasal directory.  Re-name EIS-c182t.nas to something sensible (e.g. EIS-[aircraft].nas).  Don't forget to rename the class itself!
# Copy one of the EIS .svg files from Aircraft/Instruments-3d/FG1000/MFDPages into your aircraft Nasal.  Modify it as required, noting the names of objects and how they map to the EIS.nas file.
# Edit the SVG and EIS-[aircraft].nas as appropriate.  In particular note that the Fuel submenu is used to set the contents of the fuel tanks manually, with a fuel totalizer approach.
# Copy Aircraft/Instruments-3d/FG1000/Nasal/Interfaces/GenericEISPublisher.nas into your Nasal directory, and rename it (e.g. [aircraft]EISPublisher.nas.  Don't forget to rename the class itself! Modify it to publish the correct set of properties to Emesary.  Note that for multiple engine aircraft you need to modify the publish() method.
# As noted above, you will need to load a modified version of GenericInterfaceController.nas
# Finally, modify whatever Nasal you use to load the FG1000 to pass in the new EIS class and SVG file.  Note that you need to load the EIS Controller, style and Options classes as well.
 
This is what your Nasal file may look like at the end:
 
<syntaxhighlight lang="nasal">
 
# Load a customer Interface controller
var aircraft_dir = getprop("/sim/aircraft-dir");
io.load_nasal(aircraft_dir ~ '/Nasal/GenericInterfaceController.nas', "fg1000");
 
var interfaceController = fg1000.GenericInterfaceController.getOrCreateInstance();
interfaceController.start();
 
io.load_nasal(aircraft_dir ~ '/Nasal/EIS/EIS-J3Cub.nas', "fg1000");
io.load_nasal(aircraft_dir ~ '/Nasal/EIS/EISController.nas', "fg1000");
io.load_nasal(aircraft_dir ~ '/Nasal/EIS/EISStyles.nas', "fg1000");
io.load_nasal(aircraft_dir ~ '/Nasal/EIS/EISOptions.nas', "fg1000");
 
# This is the class in EIS-J3Cub.nas, loaded above.
var EIS_Class = fg1000.EISJ3Cub;
 
# Create the FG1000 using custom EIS Class, and the appropriate .svg file.
var fg1000system = fg1000.FG1000.getOrCreateInstance(EIS_Class:EIS_Class, EIS_SVG: "Nasal/EIS/EIS-J3Cub.svg");
</syntaxhighlight>
 
=== Using custom SVG files ===
 
To assist in implementing related glass cockpits (e.g. Garmin Perspective on the Cirrus SR22T), you can specify a directory to be used instead of /Aircraft/Instruments-3d/FG1000/MFDPages/ for the SVG files used by the MFD. Note that you must copy across all the .svg files.
 
<syntaxhighlight lang="nasal">
# Create the FG1000 using custom EIS Class, and the appropriate .svg file, and a custom path to other SVG files
var fg1000system = fg1000.FG1000.getOrCreateInstance(EIS_Class:EIS_Class, EIS_SVG: "Nasal/EIS/EIS-J3Cub.svg", SVG_Path: "MFDPages/");
</syntaxhighlight>
 
 
 
=== Add multikey support ===
Include <code>Aircraft/Instruments-3d/FG1000/fg1000-multikey.xml</code> in your -set.xml file to support multikey. 
 
<syntaxhighlight lang="xml">
   <input>
    <keyboard n="0">
      <multikey include="Aircraft/Instruments-3d/FG1000/fg1000-multikey.xml"/>
    </keyboard>
   <input>
</syntaxhighlight>
 
 
See [[Howto:Add_multi-key_commands_to_an_aircraft]] for further details.
 
=== Load and start the FG1000 system ===
 
A simple FG1000 using the generic EIS, and displaying PFD on device-number 1 and an MFD on device-number 2 is as follows:
 
<syntaxhighlight lang="nasal">
var nasal_dir = getprop("/sim/fg-root") ~ "/Aircraft/Instruments-3d/FG1000/Nasal/";
io.load_nasal(nasal_dir ~ 'FG1000.nas', "fg1000");
 
# Create the FG1000
var fg1000system = fg1000.FG1000.getOrCreateInstance();
 
# Create a PFD as device 1, MFD as device 2
fg1000system.addPFD(index:1);
fg1000system.addMFD(index:2);
 
# Map the devices to placement objects Screen{i}, in this case Screen1 and Screen2
fg1000system.display(index:1);
fg1000system.display(index:2);
 
# Show the devices
fg1000system.show(index:1);
fg1000system.show(index:2);
 
#  Display a GUI version of device 1 at 50% scale.
#fg1000system.displayGUI(index:1, scale:0.5);
</syntaxhighlight>


When he gets the chance he's going to write a quick wiki article on the MapStructure layers that need to be implemented for the G1000 implementation. That might help to coordinate efforts as well.<ref>{{cite web

Stuart committed some changes to update the Select Airport dialog to use Canvas MapStructure Layers to display airport information, rather than the now deprecated map layers. The change should be largely transparent to end users - the only significant change is that your can display navigation symbols. This is all part of a long-term effort to provide the building blocks for a Garmin G1000 - these layers could be used for the airport display on the MFD, and could easily be combined with the APS layer to show a moving aircraft.<ref>{{cite web

Stuart added some new Nasal Canvas MapLayers to support Slippy Maps, as used by most web-based mapping services such as openstreetmap. This allows us to display sectional charts (for the US - vfrmap.com), and airspace information (courtesy of openaip.org), as well as a openstreetmap data. The canvas Map dialog has been updated to support these layers. Map data is retrieved over http and cached locally.<ref>{{cite web

The airspace system is in the process of changing drastically [...]  this isn't just a matter of throwing up a canvas showing some GPS waypoints and a magenta line. Modern navigators are astoundingly-complex devices — probably an order of magnitude more lines of code than FlightGear itself — and even their basic flight planning algorithms and databases (e.g. fly-by waypoints vs fly-over waypoints, open vs closed approach procedures, transitions into RNAV approaches, etc.) are far beyond the scope of anything we've tried, and we'd also need an up-to-date database far more complex than the ones we have now. Once you get to the extra features, like FIS-B weather or TIS-B traffic info over ADS-B, or TAWS (terrain alerting), we're probably in way over our heads trying to emulate even the simplest general-aviation IFR GPS.

Nasal as such is fast, and compared with the cost of rendering the terrain, rendering a canvas display is fast on the GPU (you can test by rendering but not updating a canvas display), and unless you're doing something very inefficient, calculating a display but not writing it to the property tree is fast (you can test this by disabling the write commands). It's the property I/O which you need to structure well, and then canvas will run fast. And of course the complexity of your underlying simulation costs - if you run a thermal model underneath to get real temperature reading, it costs more than inventing the numbers. But that has nothing to do with canvas. <ref>{{cite web

it's a lot of work to code all these displays which someone has to do, but there's no reason to assume it'd be hopeless performance-wise.<ref>{{cite web

we need to be realistic here: The G1000 is a fairly significant piece of computer hardware that we're going to emulate. It's not going to be "free" particularly for those on older hardware that's already struggling. However, hopefully we can offload a chunk of the logic (route management, autopilot/flight director) to the core, and do things like offline generation of terrain maps to minimie the impact.<ref>{{cite web

that's exactly the kind of device James hopes the new code can support. He's read the G1000 pilot's manual, and  *thinks* that nearly all the functions can be provided by the current GPS code It would be great if people could look over the current GPS features and indicate any pieces you think might be missing - additional commands, additional search features, extra data, or anything really. <ref>{{cite web

everyone agrees we would like to add airspace data - what we’re missing is a suitable data source with the correct license. Torsten found a raster-based source but for wider use in the sim we really need vector data, so we can render it ourselves directly. <ref>{{cite web |url    =  https://sourceforge.net/p/flightgear/mailman/message/36178857/  |title  =  <nowiki> Re: [Flightgear-devel] [flightgear/simgear] Nasal regex patch </nowiki>  |author =  <nowiki> James Turner </nowiki>  |date  =  Jan 5th, 2018  |added  =  Jan 5th, 2018  |script_version = 0.36  }}</ref>
Stuart has been in contact with the author (Sébastien MARQUE) of the ZKV-1000. While he himself doesn't plan to implement a G1000, he's very happy for it to be developed in that direction. Stuart's broad plan is to make a copy of this in fgdata or fgaddon, and use it as the basis for a G1000, taking the opportunity to use [[Canvas MFD Framework|Richard's MFD code]] and making as generic pages as possible for other glass cockpit applications.<ref>{{cite web
 
  |url    =  https://sourceforge.net/p/flightgear/mailman/message/35976465/  
For airspace data we could use [https://openflightmaps.org/ https://openflightmaps.org/] . It provides community created navigation data for many countries in (currently only) Europe with a free license.<ref>{{cite web

we definitely want vector data.  Stuart is hoping that we might convince the source of the raster data we're using at present to provide it as raw vector data, but we haven't had any luck so far.<ref>{{cite web

== Airport Data (US - only )==
At least for the US, all required information is available in the form of regularly updated UDFF files:
* https://www.ngs.noaa.gov/AERO/aero.html
* https://www.ngs.noaa.gov/AERO/uddf/WESTERN-PACIFIC/CALIFORNIA/SFO__03B.F77
* https://www.ngs.noaa.gov/AERO/annof_7.pdf
It would seem relatively straightforward to provide a scripted parser to create the corresponding charts procedurally.
As a matter of fact, this could even be done in a background thread or using a separate Python script, i.e. if we wanted to ship pre-created imagery as part of fgdata.
However, if the built-in Canvas system is extended to provide these charts, [[Phi]] could also be entirely self-contained by rendering the same  airport charts without having to depend on external data sources.

Following is the list of layers displayed by the G1000 system (see page 153 of the 190-00498-07 Rev. A), and mapping to the equivalent MapStructure Layer.
Many of these would also be good to have for other avionics/GUI dialogs, including the NavDisplay framework, which is currently re-implementing this functionality separately, i.e. not yet using MapStructure.
Following is the list of layers displayed by the G1000 system, based on the Garmin G1000 Integrated Flight Deck Pilot's Guide for the Cessna Nav III,<ref name="Pilot's Guide" /> page 153, and the mapping to the equivalent MapStructure Layer.
Richard mentioned that if he were to implement approach plates in the EFB he'd probably use raster images provided via http and provide an http service within FG to do this, or to allow the EFB to use any other external web service. Other content for the EFB could be also provided as SVG via http.<ref>{{cite web  |url    =  https://forum.flightgear.org/viewtopic.php?p=259194#p259194  |title  =  <nowiki> Re:  </nowiki>  |author =  <nowiki> Richard </nowiki>  |date  =  Sep 29th, 2015  |added  =  Sep 29th, 2015  |script_version = 0.36  }}</ref>

=== Architectural TODO List ===
This is a short list of architectural improvements I've noted during development that need to be revisited:
* Use NavMap for MFD Navigation Map, DirectTo, Nearest, Information pages.
* Separate out the HSI, tapes from the PFD and make them generic MFD UI Elements
* Improve the performance of the maps, perhaps using a cache for queries, definitely by more aggressive clipping of the SlippyMap layers based on map size.
 
The layers table shown above mentions a few limitations and ideas, such as:
=== Nasal/Canvas ===
* <image> tag support for svg.nas (patch: [http://wiki.flightgear.org/Howto:Extend_the_Canvas_SVG_module])
* MapStructure: [[MapStructure_Optimizations#Allocating_selectable_ranges_into_groups|Allocating selectable ranges into Canvas groups]]
 
=== C++ ===
* fix up [[Canvas_MapStructure#Performance|projection issues]], and adopt Gijs' [[Canvas_Development#Projections|projection handling code]] for the hard-coded PUI [[Map]], to get rid of the standard Sanson-Flamsteed projection
* adding a profile view, probably in conjunction with terrain sampling
* using atlas code to generate heightmaps/topography
* adding ESRI shapefile support to the Canvas system
* adding PDF rendering support the Canvas system


== Design ==
== Design ==
The broad structure of the Nasal files in Aircaft/Instruments-3d/FG1000/Nasal is as follows:
* MFD.nas - top level MFD device, loads the other Nasal files (likely to be moved elsewhere later) and pages.
* PageGroupControllers.nas - controller for the Page Group display in the bottom right of the MFD, controlled by the FMS knob, and which allows selection between different page groups and individual pages.
* [PageName]/[PageName].nas - MFD page, inheriting from the MFDPage.nas.  Creates any required MapStructure and hierarchy of softkeys.
* [PageName]/[PageName]Controller.nas - Controller for the MFD page and the MapStructure layers, inheriting from MFDPageController.nas
* [PageName]/[PageName]Style.nas - Style controls for the MapStructure layers for the given Page.
* [PageName]/[PageName]Options.nas - Options for the MapStructure layers for the given Page.
Key design notes:
* Most of the underlying Canvas [[MapStructure]] layers are now written (though they require styling, and/or would benefit from replacement with vector data).
* [[Emesary]] IPC framework is used to link between the MFD and underlying simulation state. This should make it easy to run the MFD on a separate FG instance, and provides a good demarkation between the individual aircraft systems and the FG1000 itself.
* Various underlying UI classes are used to handle highlighting, selection and scrolling of fields.  See [[Canvas MFD Framework]] for details of the elements now supported.
