&lt;br /&gt;
Usually, the process of &amp;quot;compiling a program&amp;quot; refers to taking its source code and running it through a so called &amp;quot;compiler&amp;quot;, which compiles, assembles and links the human readable source code to come up with the resulting binary and executable files, which contain the machine code that can be run by your computer (CPU).&lt;br /&gt;
&lt;br /&gt;
* http://en.wikipedia.org/wiki/Programming_language&lt;br /&gt;
* http://en.wikipedia.org/wiki/Source_code&lt;br /&gt;
* http://en.wikipedia.org/wiki/Compiler&lt;br /&gt;
* http://en.wikipedia.org/wiki/Machine_code&lt;br /&gt;
* http://en.wikipedia.org/wiki/Executable&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
When you simply download a pre-compiled FlightGear release, you do not have to do this yourself, because other people have already done this for you. &lt;br /&gt;
These are so called &amp;quot;release managers&amp;quot;, who often also happen to be software developers themselves.&lt;br /&gt;
&lt;br /&gt;
This is because the process of compiling a piece of software such as FlightGear requires a so called &amp;quot;build environment&amp;quot; which consists of a number of tools (such as a compiler), and custom project configuration settings to turn human readable source code into the machine code that is required for actually running a program.&lt;br /&gt;
&lt;br /&gt;
Programs are usually written in a plain text editor, imagine it like a word processor.&lt;br /&gt;
There are very complex &amp;quot;word processors&amp;quot; just for writing programs, that are specifically designed to deal with source code in various programming languages. These &amp;quot;word processors&amp;quot; are called &amp;quot;Integrated Development Environments&amp;quot; or &amp;quot;IDEs&amp;quot;, because they usually also provide comprehensive integration with the build environment, including its various tools.&lt;br /&gt;
&lt;br /&gt;
* http://en.wikipedia.org/wiki/Integrated_development_environment&lt;br /&gt;
&lt;br /&gt;
People who build FlightGear from source code and make modifications to this source code, are usually called &amp;quot;programmers&amp;quot; or more generally &amp;quot;developers&amp;quot;.&lt;br /&gt;
People who have commit rights to the master repository, are called &amp;quot;core developers&amp;quot; - because they are the ones who develop the FlightGear &amp;quot;core&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
Other programmers/developers may provide patches to the source code, which need to be reviewed, improved and committed by those core developers.&lt;br /&gt;
&lt;br /&gt;
* http://en.wikipedia.org/wiki/Programmer&lt;br /&gt;
* http://en.wikipedia.org/wiki/Software_developer&lt;br /&gt;
&lt;br /&gt;
People who do development largely within the confines of the base package (i.e. by creating or modifying aircraft and/or scenery or other base package resources) are usually also called &amp;quot;developers&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
Terms you might see here are for example &amp;quot;aircraft developer&amp;quot; or &amp;quot;scenery developer&amp;quot;. &lt;br /&gt;
Both of which implies that their work takes usually place in the base package.&lt;br /&gt;
Some people may refer to them as &amp;quot;base package developers&amp;quot; or as &amp;quot;middlware developers&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
* http://en.wikipedia.org/wiki/Middleware&lt;br /&gt;
&lt;br /&gt;
This distinction is largely due to the different set of skills required for producing these resources.&lt;br /&gt;
While programming and software development in general requires dealing with source code of programs in different programming languages, aircraft or scenery development is no longer primarily about programming in general.&lt;br /&gt;
&lt;br /&gt;
These people don't &amp;quot;program&amp;quot; aircraft or scenery, but usually they &amp;quot;design&amp;quot; things primarily (i.e. 3D models, textures) and may then add various other resources (such as for example sounds). &lt;br /&gt;
&lt;br /&gt;
* http://en.wikipedia.org/wiki/3d_modeling&lt;br /&gt;
&lt;br /&gt;
Programming in this context usually refers to tiny scripted programs that are stored in and loaded from the base package.&lt;br /&gt;
Programs written in such &amp;quot;scripting languages&amp;quot; are usually not compiled, and can be easily created by people new to programming or software development in general.&lt;br /&gt;
&lt;br /&gt;
* http://en.wikipedia.org/wiki/Scripting_language&lt;br /&gt;
&lt;br /&gt;
To cater for all these differences, these people are called aircraft/scenery &amp;quot;developers&amp;quot; because their work does not primarily comprise software development in general.&lt;br /&gt;
&lt;br /&gt;
Of course, you can also literally &amp;quot;compile&amp;quot; parts (like certain scenery or aircraft) of FlightGear to create a custom version of it. So, someone who simply takes FlightGear, and who creates a custom version of it by downstripping the base package, ommitting certain resources and adding new ones or creating custom configurations, would probably not normally be referred to as a &amp;quot;developer&amp;quot; here. The most appropriate term would be &amp;quot;Modder&amp;quot; in that case, because you are &amp;quot;modding&amp;quot; FlightGear to come up with a special version for a specific purpose, without doing any actual &amp;quot;development&amp;quot; like for example C++ coding, Nasal scripting or more generally aircraft/scenery development.&lt;br /&gt;
&lt;br /&gt;
* http://en.wikipedia.org/wiki/Modding&lt;br /&gt;
&lt;br /&gt;
Normally, &amp;quot;developing&amp;quot; something implies changing functionality and logics, in the sense of &amp;quot;programming&amp;quot; and &amp;quot;creating&amp;quot; things, features and code.&lt;br /&gt;
Someone who customizes a piece of software by editing configuration files and by adding or removing such files would usually not be called a developer.&lt;br /&gt;
&lt;br /&gt;
A configuration file provides a convenient interface to customize a program's behavior without having to be a programmer or developer.&lt;br /&gt;
&lt;br /&gt;
* http://en.wikipedia.org/wiki/Configuration_file&lt;br /&gt;
&lt;br /&gt;
Similarly, command line arguments are another way for customizing program behavior without having to change a program's source code.&lt;br /&gt;
&lt;br /&gt;
* http://en.wikipedia.org/wiki/Command_line_argument&lt;br /&gt;
&lt;br /&gt;
Imagine it like the difference between a carpenter and someone who merely takes a pre-fabricated piece of furniture (like a chair or table) and customizes it by changing its color, or adding/removing some features.&lt;br /&gt;
&lt;br /&gt;
Similarly, just because you are able to refuel your car or change your tyres you would not necessarily be referred to as a &amp;quot;car mechanic&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
So, unless you start modifying the source code (logics) of the program (FlightGear) in order to change existing behavior, your changes would normally not qualify as &amp;quot;developing&amp;quot;, even changing XML files does not fall under &amp;quot;development&amp;quot;, this is largely because XML is usually considered a markup (=description) language and not a programming language.&lt;br /&gt;
&lt;br /&gt;
* http://en.wikipedia.org/wiki/Xml&lt;br /&gt;
&lt;br /&gt;
If you were now to start documenting your experiences modding FlightGear, you would become a &amp;quot;contributor&amp;quot; and a &amp;quot;documentation writer&amp;quot; ;-)&lt;br /&gt;

&lt;br /&gt;
=== Charts ===&lt;br /&gt;
All charts that you may have to use on your flights are available at http://ais-netherlands.nl (AIS Publications &amp;gt; Integrated Package). Please note that these are the most up to date charts available, so certain situations might not have been changed in FlightGear (EHAM, EHLE and EHVK taxiways should be correct though).&lt;br /&gt;
&lt;br /&gt;
Parking positions have been created for most of the Dutch airports including EHAM, EHRD, EHVK and EHLE (A1-A6, B1 and B2).&lt;br /&gt;
&lt;br /&gt;
=== Weather information ===&lt;br /&gt;
Reallife weather information can be found at the KNMI (Dutch Meteorological institute) website.&lt;br /&gt;

&lt;br /&gt;
''01/2012: I have taken my [http://flightgear.org/forums/viewtopic.php?f=18&amp;amp;t=14870#p146436 forum response] and copied/pasted it here. Everybody is invited to contribute. While we do have a [[Volunteer]] page, we don't currently have a page dedicated to people wanting to contribute to the C++ source code, so this is an attempt to get something like this started.''&lt;br /&gt;
&lt;br /&gt;
= Welcome to FlightGear =&lt;br /&gt;
&lt;br /&gt;
Hi, and welcome to FlightGear!&lt;br /&gt;
&lt;br /&gt;
You have probably come here to learn more about implementing new features for FlightGear.&lt;br /&gt;
&lt;br /&gt;
Often, implementing new ideas and features doesn't necessarily require C++ knowledge, FlightGear has become so flexible and powerful that it is increasingly configurable even without touching the C++ source code. This is an important advantage, because building FG from source and finding your away around two fairly complex code bases (i.e. [[SimGear]] and [[FlightGear]]) can be a daunting task, even for experienced C++ developers.&lt;br /&gt;
&lt;br /&gt;
This isn't to say that C++ / programming knowledge wouldn't be useful though. And if that's where your interests are, you are certainly invited to contribute to the C++ code, too. &lt;br /&gt;
&lt;br /&gt;
== Not yet familiar with C++ ? ==&lt;br /&gt;
&lt;br /&gt;
If you don't yet know what a compiler is, what C++ is or how programming works, you may want to check out [[Howto: Understand the FlightGear development process]].&lt;br /&gt;
&lt;br /&gt;
While learning how to program is definitely possible, learning C++ in particular and becoming familiar with a complex code base like FG/SG does take a certain amount of time. In particular, setting up a working build environment to build FG from source, can be a daunting task for people without any corresponding background knowledge.&lt;br /&gt;
&lt;br /&gt;
If you know for sure, that you want to learn C++, we have a collection of helpful resources here: [[Resources#C.2B.2B_Courses|C++ resources]]. This includes a bunch of animated screen casts (i.e. video tutorials) on youtube: http://www.youtube.com/view_play_list?p=1D6727247CA35794&lt;br /&gt;
&lt;br /&gt;
== Developing without programming is possible and appreciated ==&lt;br /&gt;
&lt;br /&gt;
For non coding-related ideas on how to to start contributing, there's a dedicated article here: http://wiki.flightgear.org/Volunteer&lt;br /&gt;
&lt;br /&gt;
Also, creating new aircraft, cockpits, scenery, instruments, GUI dialogs etc doesn't require any programming knowledge at all.&lt;br /&gt;
&lt;br /&gt;
If that's what you are interested in, please check out: (developer portal links)&lt;br /&gt;
&lt;br /&gt;
== Coding but not in C++ (scripting) ==&lt;br /&gt;
&lt;br /&gt;
If you are definitely interested in coding, but not in building FlightGear from source, you may want to look into [[Nasal]] programming instead, which is FlightGear's built in scripting language, and doesn't require anything besides FlightGear itself.&lt;br /&gt;
&lt;br /&gt;
Many new ideas or features won't require any modifications to the C++ source code at all.&lt;br /&gt;
You could probably get started and implement many ideas without even touching an IDE or a compiler for quite a while.&lt;br /&gt;
&lt;br /&gt;
That might actually be the easiest route for you to proceed in the beginning. Programming knowledge would obviously still be useful, because Nasal scripting is &amp;quot;real programming&amp;quot;, many programming concepts you'll encounter in Nasal will seem familiar to people with previous programming experience.&lt;br /&gt;
&lt;br /&gt;
The &amp;quot;Nasal&amp;quot; programming language built into FG is syntactically very close to C and C++ - so you could run your own code inside FG without having to build FG from source, no need for compilers or an IDE. FlightGear IS the run time environment for Nasal code.&lt;br /&gt;
&lt;br /&gt;
If you are looking for immediate results, Nasal is probably the most promising route - simply because you don't need to look into all the tedious, non-coding related issues.&lt;br /&gt;
&lt;br /&gt;
For example, the tutorial system built into FG is entirely implemented in scripting space, and fully XML-configurable: http://wiki.flightgear.org/Tutorials&lt;br /&gt;
&lt;br /&gt;
This means that you can create/modify and improve tutorials just by editing plain text files.&lt;br /&gt;
&lt;br /&gt;
There are many more things possible using Nasal, just see the wiki.&lt;br /&gt;
&lt;br /&gt;
And if you find something not being possible in scripting space, you could either fire up your IDE and extend the interpreter or ask another contributor to provide a corresponding patch.&lt;br /&gt;
&lt;br /&gt;
== Shader programming ==&lt;br /&gt;
If you are not interested in C++ programming, but also not in Nasal scripting, there's another option: [[Shader|GLSL Shader programming]]. FlightGear has an extremely powerful &amp;quot;effects&amp;quot; framework and support for running GLSL shaders. While programming shaders for FlightGear doesn't by default require being a C++ developer, being able to build FG from source and knowing C++ can be really helpful though, especially in order to expose new properties to shaders (i.e. improving the property tree &amp;lt;-&amp;gt; shader interface).&lt;br /&gt;
&lt;br /&gt;
= Hacking the C++ code =&lt;br /&gt;
&lt;br /&gt;
From now on, this article will provide the required pointers to get you started hacking the FlightGear source code. Ideally, you already know C++, or a language very close to it, like C or Java. &lt;br /&gt;
Also, you should preferably already have experience building programs from source code, otherwise this may seem pretty frustrating if you do this for the first time, simply because FlightGear has meanwhile become a fairly complex code base with many dependencies that need to be satisfied and built in a certain order.&lt;br /&gt;
&lt;br /&gt;
= Initial advice =&lt;br /&gt;
&lt;br /&gt;
Our advice would be: Start small, start simple, communicate a lot&lt;br /&gt;
&lt;br /&gt;
* if you know you want to contribute to the source code, make sure that you are actually able to build FG from source, you can get help using the forum, the mailing list, the issue tracker or live support using IRC chat&lt;br /&gt;
* read the documentation (wiki, $FG_ROOT/Docs)&lt;br /&gt;
* start making tiny modifications to existing stuff (aircraft, scenery, source code etc)&lt;br /&gt;
* try to get to grips with how git works (we have some resources to get you started, using GUI frontends like qgit or a good IDE can be helpful)&lt;br /&gt;
* register an account at gitorious&lt;br /&gt;
* clone the FG project (SimGear, FlightGear, fgdata)&lt;br /&gt;
* browse the issue tracker for bug reports/feature requests, help triage problems, maybe provide patches too?&lt;br /&gt;
* search the archives (forum and mailing list) for discussions related to your area of interest, these contain often valuable pointers that may save you hours of work&lt;br /&gt;
* subscribe to the developers mailing list&lt;br /&gt;
* ask for advice/projects there&lt;br /&gt;
* check out the wiki for ideas to get started (Watch out, there are plenty of &amp;quot;ideas&amp;quot; listed here, but not all of them are up to date or even &amp;quot;good&amp;quot; ideas, so talk to fellow contributors first before spending any significant amounts of time implementing something)&lt;br /&gt;
* coordinate your effort with others, i.e. communicate your intentions early and ask for advice&lt;br /&gt;
* release early and often&lt;br /&gt;
* don't get frustrated :-)&lt;br /&gt;
* enjoy!&lt;br /&gt;
&lt;br /&gt;
= Project architecture =&lt;br /&gt;
FlightGear itself consists of a number of different projects and dependencies (libraries), please refer to gitorious for details. Most of FlightGear's supporting code is increasingly getting moved to the &amp;quot;SimGear&amp;quot; project.&lt;br /&gt;
&lt;br /&gt;
Basically, FlightGear depends on SimGear, while SimGear depends on some 3rd party libraries such as OpenSceneGraph, plib, OpenAL and others.&lt;br /&gt;
&lt;br /&gt;
Once you have satisfied all dependencies and built them in the right order, you can start FlightGear.&lt;br /&gt;
Note however that FlightGear also has a run time dependency: its so called &amp;quot;base package&amp;quot;, i.e. the data package that contains all resources such as scenery, GUI files, aircraft, sounds and so on. We commonly refer to this as &amp;quot;$FG_ROOT&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
The FG source tree is commonly referred to as $FG_SRC, while the SimGear source tree is often referred to as $SG_SRC.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
= The source code =&lt;br /&gt;
&lt;br /&gt;
FlightGear is multi-platform software, that runs on all major versions of MS Windows, Mac OS and Linux. That means, the FlightGear source code also needs to be written and maintained with cross-platform considerations in mind. &lt;br /&gt;
&lt;br /&gt;
The core FlightGear source code itself is largely written in C++, some C and a bunch of helper scripts. FlightGear is based on OpenGL (NOT DirectX !), OSG (OpenSceneGraph) and OpenAL (for sound). An increasing number of features are implemented in scripting space, using a high level scripting language called [[Nasal]], Nasal scripts are maintained in the base package ($FG_ROOT).&lt;br /&gt;
&lt;br /&gt;
The SimGear and FlightGear source trees both make use of the [[CMake]] build system as of 2012.&lt;br /&gt;
&lt;br /&gt;
The FlightGear project uses the decentralized source code management system &amp;quot;git&amp;quot; see [[Git]] for more info.&lt;br /&gt;
&lt;br /&gt;
The project sources are hosted at gitorious: http://gitorious.org/fg/&lt;br /&gt;
&lt;br /&gt;
If you know for sure that you'd like to fiddle with the core source code, you'll inevitably need to be able build FG from source, this is also documented in our wiki, a more recent article is to be found here: http://wiki.flightgear.org/Howto:_Build_FlightGear_with_NetBeans_using_CMake&lt;br /&gt;
&lt;br /&gt;
You can find tutorials for different platforms/OS at the end of the article.&lt;br /&gt;
&lt;br /&gt;
= Continuous Integration (CI) =&lt;br /&gt;
&lt;br /&gt;
For CI purposes, there's a dedicated build server running which rebuilds the FlightGear sources for a handful of important platforms. The server provides a simple and quick overview, it can be found here: http://flightgear.simpits.org:8080/&lt;br /&gt;
&lt;br /&gt;
Please see [[FlightGear Build Server]] for more information.&lt;br /&gt;
&lt;br /&gt;
= Patches =&lt;br /&gt;
&lt;br /&gt;
Regarding patches, please see: [[Submitting Patches]].&lt;br /&gt;
&lt;br /&gt;
Note that this article is meanwhile somewhat depreciated and these days using gitorious (and filing merge requests there) is pretty much encouraged. If your patch is related to a previously reported bug/defect, you can obviously also use the issue tracker (see below).&lt;br /&gt;
&lt;br /&gt;
In general, the FlightGear gitorious project is the entry point for new developers: http://gitorious.org/fg/&lt;br /&gt;
&lt;br /&gt;
Some more recommendations can be found at [[Recommended Project Policies]].&lt;br /&gt;
&lt;br /&gt;
In general, it is always a good idea to clone the FG repositories (i.e. SimGear, FlightGear and FGData) and start working on your own branch there. This will enable fellow contributors to easily keep track of your work, so that they can test your changes and provide feedback as required. &lt;br /&gt;
&lt;br /&gt;
To send patches upstream, gitorious merge requests are recommended. The details of which are covered at [[Merge request]].&lt;br /&gt;
&lt;br /&gt;
= Issue tracking =&lt;br /&gt;
&lt;br /&gt;
Ideas (feature requests actually) and bug reports are ideally reported using the issue tracker here: http://flightgear-bugs.googlecode.com/&lt;br /&gt;
&lt;br /&gt;
Please make sure to first search the issue tracker before possibly reporting a dupe, thanks!&lt;br /&gt;
&lt;br /&gt;
This is also an excellent place to get started helping and contributing to FG, i.e. by triaging bug reports, discussing feature requests, posting patches or finding new ideas to work on. This is also a very good place to get in touch with other core developers.&lt;br /&gt;
&lt;br /&gt;
Also, if you have some new ideas in mind, and would like to extend FlightGear in some way, it's a good idea to use the issue tracker to make feature requests. Fellow FlightGear developers will be able to provide feedback regarding your feature request and tell you directly if and how exactly your idea can be best implemented.&lt;br /&gt;
&lt;br /&gt;
= Talking to fellow FlightGear developers =&lt;br /&gt;
Most core development related discussions are handled using the developers mailing list: http://www.flightgear.org/mail.html&lt;br /&gt;
&lt;br /&gt;
There's a fully searchable archive available here: http://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/&lt;br /&gt;
&lt;br /&gt;
In addition, the FlightGear forums are increasingly used for interesting development related discussions, please note though that these are usually not specific to FG core development, but instead general development: http://flightgear.org/forums/&lt;br /&gt;
&lt;br /&gt;
If there's something particular that you are interested in, it's always a good idea to search these resources (wiki, forum, mailing list) to find related discussions.&lt;br /&gt;
&lt;br /&gt;
= Flight dynamics =&lt;br /&gt;
Improving the flight dynamics often doesn't require any C++ changes, FlightGear provides a powerful FDM interface and different FDM engines (namely JSBSim and YaSim), both of which are entirely configurable by using XML files.&lt;br /&gt;
&lt;br /&gt;
For JSBSim, please see: http://jsbsim.sourceforge.net/&lt;br /&gt;
&lt;br /&gt;
= Important docs =&lt;br /&gt;
There's a wealth of documentation to get you started available in [http://gitorious.org/fg/fgdata/trees/master/Docs $FG_ROOT/Docs]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Even more documentation can be found in our wiki, here: http://wiki.flightgear.org/&lt;br /&gt;
&lt;br /&gt;
The wiki is divided into different &amp;quot;portals&amp;quot;, you'll probably be interested in the developers portal here: http://wiki.flightgear.org/Portal:Developer&lt;br /&gt;
&lt;br /&gt;
You are obviously invited to start your own wiki articles, in order to document your projects or help improving existing documentation. Also, some core developers actually use the wiki to post their own development roadmaps. For example, see: [[Plan-zakalawe]] or [[Project Rembrandt]].&lt;br /&gt;
&lt;br /&gt;
== FlightGear ==&lt;br /&gt;
Don't worry if your C++ experience should be dated: In many parts, the FlightGear code base is still somewhat archaic and not very modern, so you won't find too many occurrences of really advanced C++ concepts, in many places you'll just find simple &amp;quot;C with classes&amp;quot; uses, some STL and inheritance. &lt;br /&gt;
But complex C++ features (such as advanced templates or meta-programming are not too common actually).&lt;br /&gt;
&lt;br /&gt;
One of the simplest ways to add new features to FlightGear is adding new commands to it, so called &amp;quot;fgcommands&amp;quot; (i.e. &amp;quot;FlightGear commands&amp;quot;). &lt;br /&gt;
For additional information, please see this tutorial: [[Howto: Add new fgcommands to FlightGear]].&lt;br /&gt;
&lt;br /&gt;
== Programming resources ==&lt;br /&gt;
If you need to read up on something programming related, such as C++, the STL, OpenGL, shaders etc, the wiki has plenty of programming resources to get you started: [[Resources]].&lt;br /&gt;
&lt;br /&gt;
== SimGear ==&lt;br /&gt;
The SimGear code base is somewhat less archaic and more modern actually. And if you are interested in contributing to the OpenGL/SceneGraph department, you'll inevitably need to look into OpenSceneGraph (OSG), too - which really is &amp;quot;modern C++&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
SimGear is fairly well-maintained code base that contains a fair amount of doxygen comments, that means that it's easy to create doxygen documentation for SimGear. For example, see: http://simgear.sourceforge.net/doxygen/&lt;br /&gt;
&lt;br /&gt;
Note that, at the time of reading, this may be outdated, so if you are interested in using the latest doxygen docs, you are well advised to run doxygen against your own latest simgear clone.&lt;br /&gt;
&lt;br /&gt;
Also, you can get a fair amount of information out of the FG sources by running them through doxygen, too.&lt;br /&gt;
&lt;br /&gt;
== Plain C ? (Nasal) ==&lt;br /&gt;
If your C++ is rusty and you'd just like to get started quickly, there are also certain FG components that are strictly (largely) pure C, the Nasal interpreter is just one example (Nasal is FlightGear's built in scripting language): http://wiki.flightgear.org/Nasal_scripting_language&lt;br /&gt;
&lt;br /&gt;
The Nasal interpreter is part of the SimGear project, and can be found in $SG_SRC/nasal: http://gitorious.org/fg/simgear/trees/next/simgear/nasal&lt;br /&gt;
&lt;br /&gt;
Adding new extension functions to the built-in Nasal interpreter is documented here: [[Howto: Extend Nasal]].&lt;br /&gt;
&lt;br /&gt;
There's also a separate wiki article providing a list of issues related to the Nasal interpreter itself: [[Improving Nasal]].&lt;br /&gt;
&lt;br /&gt;
None of this requires any C++ knowledge!&lt;br /&gt;
&lt;br /&gt;
Only the scripting interface connecting the Nasal interpreter and FlightGear is implemented in C++, it can be found in $FG_SRC/Scripting: http://gitorious.org/fg/flightgear/trees/next/src/Scripting&lt;br /&gt;
&lt;br /&gt;
= Getting started =&lt;br /&gt;
Once you have found something you are interested in, you can search the wiki, archives (mailing list and forums) or the issue tracker to find suitable projects to work on, for example: http://code.google.com/p/flightgear-bugs/issues/list?can=2&amp;amp;q=nasal&amp;amp;colspec=ID+Type+Status+Priority+Summary+Aircraft+Milestone&amp;amp;cells=tiles&lt;br /&gt;
&lt;br /&gt;
== Talk about your plans ==&lt;br /&gt;
Before you start any serious efforts, please make sure to get in touch with other contributors. Ideally, using the developers mailing list or the forum. This is to ensure that others know about your plans, i.e. to avoid duplicate work, but also conflicting approaches. &lt;br /&gt;
&lt;br /&gt;
Often, FlightGear developers have certain ideas and plans for their projects, so it's good to coordinate your ideas with fellow contributors. In addition, you can get valuable feedback from experienced contributors this way, which may save you countless hours of time and lots of frustration.&lt;br /&gt;
&lt;br /&gt;
== Adding new subsystems ==&lt;br /&gt;
If you are interested in adding new subsystems to FG, you may want to check out this: [[Howto:Create new subsystems]].&lt;br /&gt;
&lt;br /&gt;
== The property tree ==&lt;br /&gt;
The FlightGear property tree is documented here: [[Howto:Work with the Property Tree API]]&lt;br /&gt;
&lt;br /&gt;
= Finally =&lt;br /&gt;
&lt;br /&gt;
...please don't get discouraged if you shouldn't get too much feedback in the beginning, probably many contributors are busy preparing the next release: http://wiki.flightgear.org/Release_plan&lt;br /&gt;

''01/2012: I have taken my [http://flightgear.org/forums/viewtopic.php?f=18&amp;amp;t=14870#p146436 forum response] and copied/pasted it here. Everybody is invited to contribute. While we do have a [[Volunteer]] page, we don't currently have a page dedicated to people wanting to contribute to the C++ source code, so this is an attempt to get something like this started.''&lt;br /&gt;
&lt;br /&gt;
= Welcome to FlightGear =&lt;br /&gt;
&lt;br /&gt;
Hi, and welcome to FlightGear!&lt;br /&gt;
&lt;br /&gt;
You have probably come here to learn more about implementing new features for FlightGear.&lt;br /&gt;
&lt;br /&gt;
Often, implementing new ideas and features doesn't necessarily require C++ knowledge, FlightGear has become so flexible and powerful that it is increasingly configurable even without touching the C++ source code. This is an important advantage, because building FG from source and finding your away around two fairly complex code bases (i.e. [[SimGear]] and [[FlightGear]]) can be a daunting task, even for experienced C++ developers.&lt;br /&gt;
&lt;br /&gt;
This isn't to say that C++ / programming knowledge wouldn't be useful though. And if that's where your interests are, you are certainly invited to contribute to the C++ code, too. &lt;br /&gt;
&lt;br /&gt;
== Not yet familiar with C++ ? ==&lt;br /&gt;
&lt;br /&gt;
If you don't yet know what a compiler is, what C++ is or how programming works, you may want to check out [[Howto: Understand the FlightGear development process]].&lt;br /&gt;
&lt;br /&gt;
While learning how to program is definitely possible, learning C++ in particular and becoming familiar with a complex code base like FG/SG does take a certain amount of time. In particular, setting up a working build environment to build FG from source, can be a daunting task for people without any corresponding background knowledge.&lt;br /&gt;
&lt;br /&gt;
If you know for sure, that you want to learn C++, we have a collection of helpful resources here: [[Resources#C.2B.2B_Courses|C++ resources]]. This includes a bunch of animated screen casts (i.e. video tutorials) on youtube: http://www.youtube.com/view_play_list?p=1D6727247CA35794&lt;br /&gt;
&lt;br /&gt;
== Developing without programming is possible and appreciated ==&lt;br /&gt;
&lt;br /&gt;
For non coding-related ideas on how to to start contributing, there's a dedicated article here: http://wiki.flightgear.org/Volunteer&lt;br /&gt;
&lt;br /&gt;
Also, creating new aircraft, cockpits, scenery, instruments, GUI dialogs etc doesn't require any programming knowledge at all.&lt;br /&gt;
&lt;br /&gt;
If that's what you are interested in, please check out: (developer portal links)&lt;br /&gt;
&lt;br /&gt;
== Coding but not in C++ (scripting) ==&lt;br /&gt;
&lt;br /&gt;
If you are definitely interested in coding, but not in building FlightGear from source, you may want to look into [[Nasal]] programming instead, which is FlightGear's built in scripting language, and doesn't require anything besides FlightGear itself.&lt;br /&gt;
&lt;br /&gt;
Many new ideas or features won't require any modifications to the C++ source code at all.&lt;br /&gt;
You could probably get started and implement many ideas without even touching an IDE or a compiler for quite a while.&lt;br /&gt;
&lt;br /&gt;
That might actually be the easiest route for you to proceed in the beginning. Programming knowledge would obviously still be useful, because Nasal scripting is &amp;quot;real programming&amp;quot;, many programming concepts you'll encounter in Nasal will seem familiar to people with previous programming experience.&lt;br /&gt;
&lt;br /&gt;
The &amp;quot;Nasal&amp;quot; programming language built into FG is syntactically very close to C and C++ - so you could run your own code inside FG without having to build FG from source, no need for compilers or an IDE. FlightGear IS the run time environment for Nasal code.&lt;br /&gt;
&lt;br /&gt;
If you are looking for immediate results, Nasal is probably the most promising route - simply because you don't need to look into all the tedious, non-coding related issues.&lt;br /&gt;
&lt;br /&gt;
For example, the tutorial system built into FG is entirely implemented in scripting space, and fully XML-configurable: http://wiki.flightgear.org/Tutorials&lt;br /&gt;
&lt;br /&gt;
This means that you can create/modify and improve tutorials just by editing plain text files.&lt;br /&gt;
&lt;br /&gt;
There are many more things possible using Nasal, just see the wiki.&lt;br /&gt;
&lt;br /&gt;
And if you find something not being possible in scripting space, you could either fire up your IDE and extend the interpreter or ask another contributor to provide a corresponding patch.&lt;br /&gt;
&lt;br /&gt;
== Shader programming ==&lt;br /&gt;
If you are not interested in C++ programming, but also not in Nasal scripting, there's another option: [[Shader|GLSL Shader programming]]. FlightGear has an extremely powerful &amp;quot;effects&amp;quot; framework and support for running GLSL shaders. While programming shaders for FlightGear doesn't by default require being a C++ developer, being able to build FG from source and knowing C++ can be really helpful though, especially in order to expose new properties to shaders (i.e. improving the property tree &amp;lt;-&amp;gt; shader interface).&lt;br /&gt;
&lt;br /&gt;
= Hacking the C++ code =&lt;br /&gt;
&lt;br /&gt;
From now on, this article will provide the required pointers to get you started hacking the FlightGear source code. Ideally, you already know C++, or a language very close to it, like C or Java. &lt;br /&gt;
Also, you should preferably already have experience building programs from source code, otherwise this may seem pretty frustrating if you do this for the first time, simply because FlightGear has meanwhile become a fairly complex code base with many dependencies that need to be satisfied and built in a certain order.&lt;br /&gt;

Also, if you have some new ideas in mind, and would like to extend FlightGear in some way, it's a good idea to use the issue tracker to make feature requests. Fellow FlightGear developers will be able to provide feedback regarding your feature request and tell you directly if and how exactly your idea can be best implemented.&lt;br /&gt;
&lt;br /&gt;
= Talking to fellow FlightGear developers =&lt;br /&gt;
Most core development related discussions are handled using the developers mailing list: http://www.flightgear.org/mail.html&lt;br /&gt;
&lt;br /&gt;
There's a fully searchable archive available here: http://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/&lt;br /&gt;
&lt;br /&gt;
In addition, the FlightGear forums are increasingly used for interesting development related discussions, please note though that these are usually not specific to FG core development, but instead general development: http://flightgear.org/forums/&lt;br /&gt;
&lt;br /&gt;
If there's something particular that you are interested in, it's always a good idea to search these resources (wiki, forum, mailing list) to find related discussions.&lt;br /&gt;
&lt;br /&gt;
= Flight dynamics =&lt;br /&gt;
Improving the flight dynamics often doesn't require any C++ changes, FlightGear provides a powerful FDM interface and different FDM engines (namely JSBSim and YaSim), both of which are entirely configurable by using XML files.&lt;br /&gt;
&lt;br /&gt;
For JSBSim, please see: http://jsbsim.sourceforge.net/&lt;br /&gt;
&lt;br /&gt;
= Important docs =&lt;br /&gt;
There's a wealth of documentation to get you started available in [http://gitorious.org/fg/fgdata/trees/master/Docs $FG_ROOT/Docs]&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Even more documentation can be found in our wiki, here: http://wiki.flightgear.org/&lt;br /&gt;
&lt;br /&gt;
The wiki is divided into different &amp;quot;portals&amp;quot;, you'll probably be interested in the developers portal here: http://wiki.flightgear.org/Portal:Developer&lt;br /&gt;
&lt;br /&gt;
You are obviously invited to start your own wiki articles, in order to document your projects or help improving existing documentation. Also, some core developers actually use the wiki to post their own development roadmaps. For example, see: [[Plan-zakalawe]] or [[Project Rembrandt]].&lt;br /&gt;
&lt;br /&gt;
== FlightGear ==&lt;br /&gt;
Don't worry if your C++ experience should be dated: In many parts, the FlightGear code base is still somewhat archaic and not very modern, so you won't find too many occurrences of really advanced C++ concepts, in many places you'll just find simple &amp;quot;C with classes&amp;quot; uses, some STL and inheritance. &lt;br /&gt;
But complex C++ features (such as advanced templates or meta-programming are not too common actually).&lt;br /&gt;
&lt;br /&gt;
One of the simplest ways to add new features to FlightGear is adding new commands to it, so called &amp;quot;fgcommands&amp;quot; (i.e. &amp;quot;FlightGear commands&amp;quot;). &lt;br /&gt;
For additional information, please see this tutorial: [[Howto: Add new fgcommands to FlightGear]].&lt;br /&gt;
&lt;br /&gt;
== Programming resources ==&lt;br /&gt;
If you need to read up on something programming related, such as C++, the STL, OpenGL, shaders etc, the wiki has plenty of programming resources to get you started: [[Resources]].&lt;br /&gt;
&lt;br /&gt;
== SimGear ==&lt;br /&gt;
The SimGear code base is somewhat less archaic and more modern actually. And if you are interested in contributing to the OpenGL/SceneGraph department, you'll inevitably need to look into OpenSceneGraph (OSG), too - which really is &amp;quot;modern C++&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
SimGear is fairly well-maintained code base that contains a fair amount of doxygen comments, that means that it's easy to create doxygen documentation for SimGear. For example, see: http://simgear.sourceforge.net/doxygen/&lt;br /&gt;
&lt;br /&gt;
Note that, at the time of reading, this may be outdated, so if you are interested in using the latest doxygen docs, you are well advised to run doxygen against your own latest simgear clone.&lt;br /&gt;
&lt;br /&gt;
Also, you can get a fair amount of information out of the FG sources by running them through doxygen, too.&lt;br /&gt;
&lt;br /&gt;
== Plain C ? (Nasal) ==&lt;br /&gt;
If your C++ is rusty and you'd just like to get started quickly, there are also certain FG components that are strictly (largely) pure C, the Nasal interpreter is just one example (Nasal is FlightGear's built in scripting language): http://wiki.flightgear.org/Nasal_scripting_language&lt;br /&gt;
&lt;br /&gt;
The Nasal interpreter is part of the SimGear project, and can be found in $SG_SRC/nasal: http://gitorious.org/fg/simgear/trees/next/simgear/nasal&lt;br /&gt;
&lt;br /&gt;
Adding new extension functions to the built-in Nasal interpreter is documented here: [[Howto: Extend Nasal]].&lt;br /&gt;
&lt;br /&gt;
There's also a separate wiki article providing a list of issues related to the Nasal interpreter itself: [[Improving Nasal]].&lt;br /&gt;
&lt;br /&gt;
None of this requires any C++ knowledge!&lt;br /&gt;
&lt;br /&gt;
Only the scripting interface connecting the Nasal interpreter and FlightGear is implemented in C++, it can be found in $FG_SRC/Scripting: http://gitorious.org/fg/flightgear/trees/next/src/Scripting&lt;br /&gt;
&lt;br /&gt;
= Getting started =&lt;br /&gt;
Once you have found something you are interested in, you can search the wiki, archives (mailing list and forums) or the issue tracker to find suitable projects to work on, for example: http://code.google.com/p/flightgear-bugs/issues/list?can=2&amp;amp;q=nasal&amp;amp;colspec=ID+Type+Status+Priority+Summary+Aircraft+Milestone&amp;amp;cells=tiles&lt;br /&gt;
&lt;br /&gt;
== Talk about your plans ==&lt;br /&gt;
Before you start any serious efforts, please make sure to get in touch with other contributors. Ideally, using the developers mailing list or the forum. This is to ensure that others know about your plans, i.e. to avoid duplicate work, but also conflicting approaches. &lt;br /&gt;
&lt;br /&gt;
Often, FlightGear developers have certain ideas and plans for their projects, so it's good to coordinate your ideas with fellow contributors. In addition, you can get valuable feedback from experienced contributors this way, which may save you countless hours of time and lots of frustration.&lt;br /&gt;
&lt;br /&gt;
== Adding new subsystems ==&lt;br /&gt;
If you are interested in adding new subsystems to FG, you may want to check out this: [[Howto:Creating new Subsystems]].&lt;br /&gt;
&lt;br /&gt;
== The property tree ==&lt;br /&gt;
The FlightGear property tree is documented here: [[Howto:Work with the Property Tree API]]&lt;br /&gt;
&lt;br /&gt;
= Finally =&lt;br /&gt;
&lt;br /&gt;
...please don't get discouraged if you shouldn't get too much feedback in the beginning, probably many contributors are busy preparing the next release: http://wiki.flightgear.org/Release_plan&lt;br /&gt;
&lt;br /&gt;

		<summary type="html">&lt;p&gt;Singaearth: /* jEdit */&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;There's Nasal syntax-highlighting support available for some editors, which is a big advantage, as it makes Nasal coding much easier. It can often point to syntax errors and so reduce the number of tedious time-consuming and unproductive FlightGear runs.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
= Notepad++ =&lt;br /&gt;
http://dl.dropbox.com/u/1463693/nasal.xml&lt;br /&gt;
&lt;br /&gt;
Instructions are here: http://superuser.com/questions/62474/notepad-custom-syntax-highlighting-setting-where-to-look-for-it&lt;br /&gt;
&lt;br /&gt;
= jEdit = &lt;br /&gt;
There's a syntax highlighting mode for jEdit, programmer's text editor&lt;br /&gt;
&lt;br /&gt;
Included are some of Nasal's internal functions and those functions currently implemented in NasalSys.cxx&lt;br /&gt;
To use, add the content of the catalog inside your own catalog (do NOT overwrite the file) and nasal.xml in /home/USER/.jedit/modes&lt;br /&gt;
&lt;br /&gt;
Restart jEdit and you can use it. Current extension is .nas, you can add your own extension and functions.&lt;br /&gt;
This mode is heavily based on the Javascript mode.&lt;br /&gt;
&lt;br /&gt;
Get it here: http://www.jedit.org/&lt;br /&gt;
&lt;br /&gt;
= Vim =&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
It also makes understanding other people's code easier. One such editor is the free vim or its gui variant gvim. &lt;br /&gt;
&lt;br /&gt;
It's not for everyone but it's free, and testing it doesn't hurt: http://www.vim.org/. &lt;br /&gt;
&lt;br /&gt;
The syntax definition file comes with the FlightGear code (http://gitorious.org/fg/flightgear/blobs/next/scripts/syntax/nasal.vim). Highlighting works even for Nasal embedded in XML files (type &amp;quot;:set ft=nasal&amp;quot;, where ft stands for file-type)&lt;br /&gt;
&lt;br /&gt;
Here's an example, which demonstrates a short code segment with three syntax errors as well as the highlighting of a matching pair of parentheses (yellow) and trailing spaces (blue x). (The leading blue dots aren't on by default. They help to spot tab crimes.)&lt;br /&gt;
&lt;br /&gt;
[[File:Vim-nasal-syntax-highlighting.png|400px|thumb|Screen shot illustrating syntax highlighting in Vim]]&lt;br /&gt;
&lt;br /&gt;
= Other editors =&lt;br /&gt;
Nasal being syntactically very close to other programming languages like C, Php or JavaScript, you can get some usable highlighting even without real Nasal support:&lt;br /&gt;
&lt;br /&gt;
* TextMate [http://flightgear.org/forums/viewtopic.php?f=30&amp;amp;t=12495&amp;amp;p=128116&amp;amp;hilit=syntax+nasal#p127828]&lt;br /&gt;
* SciTe [http://flightgear.org/forums/viewtopic.php?f=30&amp;amp;t=9260&amp;amp;p=94521&amp;amp;hilit=syntax+nasal#p94521]&lt;br /&gt;
* gEdit (Linux) : Using the 'Octave' highlighting mode, most of the nasal functions work.&lt;br /&gt;
&lt;br /&gt;
= FlightGear Wiki =&lt;br /&gt;
A common approach in code examples on the wiki is to use php syntax highlighting beween &amp;lt;code&amp;gt;&amp;amp;lt;syntaxhighlight&amp;amp;gt;&amp;lt;/code&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
 &amp;lt;nowiki&amp;gt;&amp;lt;syntaxhighlight lang=&amp;quot;php&amp;quot;&amp;gt;&lt;br /&gt;
# hello.nas&lt;br /&gt;
print('Hello World!');&lt;br /&gt;
&amp;lt;/syntaxhighlight&amp;gt;&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Which renders into:&lt;br /&gt;
&amp;lt;syntaxhighlight lang=&amp;quot;php&amp;quot;&amp;gt;&lt;br /&gt;
# hello.nas&lt;br /&gt;
print('Hello World!');&lt;br /&gt;
&amp;lt;/syntaxhighlight&amp;gt;&lt;br /&gt;

The Hughes XF-11 was an experimental 1940s reconnaissance aircraft by Hughes aircraft. A crash in 1946 nearly killed the test pilot Howard Hughes. [http://www.check-six.com/Crash_Sites/XF-11_crash_site.htm] This 1946 version had 2 counter-rotating props powered by 2 piston engines, which is the FG version.&lt;br /&gt;
&lt;br /&gt;
Note that the designation is not part of the later F-# fighter sequence; in that sequence see Grumman F-11 Tiger (formerly F11F Tiger under the Navy's designation  before 1962).&lt;br /&gt;

The H-1 Racer made by Hughes aircraft, was a record setting piston engine experimental aircraft.  This aircraft is currently only for [[CVS]]. (see also the [http://cvs.flightgear.org/viewvc/data/Aircraft/H1-Racer/ Developer Link] on [[CVS]])&lt;br /&gt;
&lt;br /&gt;
The original racer set records in the 1930s with Howard Hughes at the controls at its first flight in 1935. A reproduction was completed in 2002, but crashed the next year (2003).  The FlightGear H-1 is a 1937 version of the aircraft. &lt;br /&gt;
&lt;br /&gt;
The original Hughes H-1 survives and is on display at the [[National Air and Space Museum]].&lt;br /&gt;

The '''Deperdussin''' was a single  piston-engined propeller monoplane from 1912 by the Deperdussin Company. It featured a [[monocoque]] construction and streamlined fuselage. It broke several speed records and won the Gordon Bennett Trophy, and the floatplane version was the winner of the first Schneider Trophy. There are a few versions of the Deperdussin, but the FlightGear version debuted on CVS ([http://cvs.flightgear.org/viewvc/data/Aircraft/ CVS]) in 2009.&lt;br /&gt;
&lt;br /&gt;
There was also a 1910 Deperdussin [http://www.sigmfg.com/IndexText/SIGRC92.html]&lt;br /&gt;

The H-4 (HK-1) was designed as a super-large transatlantic cargo aircraft. Developed by Hughes-Kaiser and then Hughes, the need for the airplane evaporated when the war ended.  Hughes went on to fly it in 1947, and it was maintained in ready to fly condition until his death. The surviving example is at the [[Evergreen Aviation Museum]] in the USA.&lt;br /&gt;
&lt;br /&gt;
The aircraft featured 8 piston engines and wood construction.&lt;br /&gt;

}}The '''Grob G 109''' is a light [[aircraft]] developed by [[:Category:Grob|Grob Aerospace]] of Mindelheim Mattsies in Germany. It first flew in 1980.&lt;br /&gt;
The G 109 was the first motor [[:Category:Gliders|glider]] built using composite construction to be granted Federal Aviation Administration approval.&lt;br /&gt;
&lt;br /&gt;
==Aircraft help==&lt;br /&gt;
The Grob 109 can take-off on its own, and under its own power, climb to altitude and can be flown with the engine in operation or not in operation. When the engine is not being used, the aircraft is a true glider and has performance comparable to many popular training gliders.&lt;br /&gt;
