FGCom is an addon for FlightGear. With FGCom (and the infrastructure behind it), FlightGear now has a realtime voice communication system which enriches the FlightGear capabilities, especially for multiplayer events, like:
- Flying in groups, see the multiplayer events forum
- Invite friends to a guided sightseeing tour in your most beloved area or do “Fly In's”
- Do military training like “Air-Air-Refuelling”, “Dog fights”, “Escort flights”, etc.
- Offering additional services at an airport like ATC, snowplows, pushbacks, racing-events etc.
- Have a real time flighttraining (e.g. pilot in Hongkong, teacher in Sydney), do Glider-towing, ask for on-line support during flight or just ask somebody flying a plane of interest about specifics.
- Or just sit in a cockpit in Germany while sightseeing San Francisco in a C172, voice-chat with a Texan in a plane I dreamed of as a boy (Super Constellation) and both getting information from a New Zealand guy (it shall be a wonderful island – but do real people live there? He said: Yes!!).
- And much more!
You can even use it in models without radios - just use the standard FlightGear menu (Equipment > Radio Settings).
In the future FGCom surely will extend further and surely will get a “Speech to Text” capability in order to also integrate the text-based automated ATC-routines inside FlightGear, for details see previous discussions summarized at Integrating FGCom, which also has a section on embedded TTS support through flite, which was previously discussed on the devel list by some core developers.

The Client installation
If you are satisfied with the operation and response times of your current FlightGear installation, then you should see no significant difference after adding the FGCom. If your FlightGear installation runs already a little marginal, then you might experience some delays when many new airplane-models etc. must be loaded. This may happen when starting up at a busy airport. You can monitor/verify such a "short-time overload" in the FlightGear command-window.
For details see the common hardware and driver requirements.
Of course you will also need a connection to the internet for this real-time, worldwide voice communication.
|FlightGear||The basic FlightGear Flight Simulation installation. This must be installed prior to installing FGCom (except if installing the Linux "Git complete" version which can install FGCom and FlightGear concurrently).|
|Multiplayer||“Multiplayer” is not an installable program but an integrated function of FGFS. As the name says, it enables communication of several players via a chat-function (until now per keyboard - now also with this vocal interface: FGCom).|
Nice to have
|FGrun||This FlightGear Launch Control (also known as FG Wizard), is a graphical front end to start the FGFS. This makes it very easy to startup the FGFS with all its possible options. In some newer distributions this is already part of the basic FGFS installation package.|
|MPMap||MPMap is a pure browser application based on Google Maps, so it does not need any installation, except a Web-Browser. With MPMap you can watch all Multiuser-planes worldwide on a road-map, satellite picture or a composite of both. It includes most of the airports, navigational aids, and current weather information. So it can be used for preflight planning, without having the FGFS started or even installed. But it needs a constant connection to the Internet - on the other hand you can do your preflight planning anywhere where there is a PC, connected to the Internet.|
|SkyVector||SkyVector is a standalone Browser-Application. It does present a fantastic Fight-Planning tool, showing similar aspects like the "MPMap" - but is based on a an real Aeronatical map ("Sectional"). On it you can graphically plan your routes - see the "Help Video" icon in the Top-Menubar.
But it does not directly link into FGFS, MPMap or Multiplayer -- and it covers only the domestic USA.
|Atlas||Atlas displays the current position of your airplane on an landscape type of map together with navigational information. It derives its data direct out of the installed FGFS databases. So you do not need any connections to the Internet.|
|Festival||Festival is a TTS (Text To Speech) system that can convert all in the FGFS displayed written text (ATC, Chat, etc.) into speech and put it in your loudspeakers.|
Install on Linux
For Linux-Systems there are various ways to install:
- Scripted Installation (recommended)
mkdir fgcom cd fgcom wget http://www.gitorious.org/fg/fgmeta/blobs/raw/master/download_and_compile.sh chmod +x ./download_and_compile.sh ./download_and_compile.sh PLIB FGCOM
... it will ask 2 x for the root password then it looks like this:
[ 95%] Building CXX object CMakeFiles/fgcom.dir/src/fgcom.cpp.o [ 97%] Building CXX object CMakeFiles/fgcom.dir/src/fgcom_init.cpp.o [ 98%] Building CXX object CMakeFiles/fgcom.dir/src/position.cpp.o [100%] Building CXX object CMakeFiles/fgcom.dir/src/utils.cpp.o Linking CXX executable fgcom [100%] Built target fgcom -- Install configuration: "Release" -- Installing: /big/home/mherweg/flightgear/fgcom/try/install/fgcom/bin/fgcom -- Installing: /big/home/mherweg/flightgear/fgcom/try/install/fgcom/share/fgcom/positions.txt -- Installing: /big/home/mherweg/flightgear/fgcom/try/install/fgcom/share/fgcom/special_frequencies.txt To start fgfs, run the run_fgfs.sh file To start terrasync, run the run_terrasync.sh file To start fgrun, run the run_fgrun.sh file To start fgcom, run the run_fgcom.sh file To start fgcom GUI, run the run_fgcomgui.sh file To start atlas, run the run_atlas.sh file Usage: ./download_and_compile.sh -h for help
then you can start fgcom like this:
- Downloading from the “Distributor” (Debian, Ubuntu, Red Hat, Suse, etc.).
- Advantage: This is the easiest way and ensures that maintenance and services for this package and all concurrencies to it are provided automatically for a reasonable time-frame.
- Disadvantage: The availability of those packages is usually very late and most Distributors do not cover all FGFS-features. To our knowledge none of the Distributors has an FGCom package available as of March 2009.
- Installation: Follow the usual procedures of your distributer on how to install additional packages.
- Installing a “Git complete”
- Advantage: It is the very easiest form of installation and installs in one step all prerequisite/companion modules (FGFS, FGrun, FGcom, PLIB, OSG, Simgear, AT). Also it can be added and removed from the system without disturbing the rest of the system (Libraries, Menus, Structures, etc.). It was tested on several Ubuntu and Debian systems.
- Disadvantage: No automated maintenance available. The handling is a little different from the standard Menu-driven practice.
- Installation: Scripted Compilation on Linux Debian/Ubuntu
- Compiling it locally:
- Advantage: After a successful installation it is integrated into the system like a package from the distributor.
- Disadvantage: No automated maintenance available. Also the user should have some basic knowledge of his system and its devices.
- Installation: instructions
Then continue with testing on FGCOM Testing.
Install on Mac
You can download the "MacFlightGear"-Application from the FlightGear download-center. The current version 2.0.0 of the code does contain the FGCom and works for OSX >= 10.5. (with OSX versions < 10.5 you will end up with a generic "bus error" message).
Install on Windows
Please use the Windows installation description, available through FGCOM for Windows.
During testing we will test/adjust:
- the basic FGCom functions without FlightGear
- FGCom together with FlightGear
- the microphone and loudspeaker system
For these tests please refer to FGCOM Testing.
Functional test & user briefing
Experiences pointed out, that the cooperation between FGCom and FlightGear works more reliable, if FlightGear is started first. So we will start with setting up a flight-test-environment:
We suggest to use FGRun to define required and/or proposed settings, in order to avoid typo-errors etc. If you keep the “Show command line” active (compare item 3 following), you also get the correct writing for all the command-options (in case you later want to start from a command-line and/or out of a script). In the following we will just point out those commands which are significant for FGCom-operation:
If you don't have an icon available to start FGrun, then start FlightGear manually:
- Start a command-window
- Change into the directory in which FGFS was installed
- Execute the following command or something similar
|Linux Git:||cd ~/fgfs|
cd 'C:\Program Files\Flightgear\win32'
Wait for the program window to start and then define:
- Start by choosing an airplane. For this first try we suggest the Cessna C172P, so we have a common understanding in the following. Also be aware of some airplane-designers reassigning keyboard-keys (e.g. the “space-bar”), thus you may not have the PTT-key (“Push To Talk”) available. See FGCOM#Tips and Tricks.
→ Click "Next".
- As starting place please define the airport KPAO (Palo Alto) runway 13, so we all see the same messages in the following reports. A second reason for KPAO is of course that KPAO comes already with the basic scenery-package, and thus is available for everybody.
→ Click "Next".
- Define the Multiplayer options: (see Howto: Multiplayer for details).
- “AI models” must be activated in order to see all traffic
- “Multiplayer” must be activated
- type “mpserverXX.flightgear.org” into the field “Hostname:”, replace “XX” with the server number nearest you - select it in http://pigeond.net/flightgear/mpstatus/. Actually it does not matter which server you take (as long as it is online and not as overcrowded as mpserver02) - you might try which server gives you the best response-times.
- Insert your “Callsign:” (max. 7 characters)
- define the “in” and “out” ports both with the standard “5000”
- With "Load/Save as" you may build up yourself a library of settings for different airports.
→ Click "Advanced".
- In the “Advanced Options” check the following sections (click/select them in the left column):
- General: Those settings were defined before. Check “Control”, if needed select your input device (Joystick, Keyboard, or Mouse).
- Features: “AI Traffic” should be activated already
- Initial Position: You may define here an unique “starting/parking” position outside a runway. Thus you could avoid starting on top of another player, because most of them pile up at the end of a runway. You can look up a position in the MPMap: (see next item)
- Be aware that any data defined here override already predefined data (e.g. also an airport and runway). So do not forget to change/delete the here defined positions if some time you want to start from another airport. Of course you may save/reload settings for different airports, see "Load/save as" on the main window.
- Open the MPMap
- if the control-panel is not visible click onto "FGMap | mpserver01:5000 | pilots: 7”
- click on “nav”
- disable all options except “apt code”
- type “KPAO” into the filed “Navaids lookup”
- hit ENTER or click onto the reading-glass symbol
- click onto the appearing line “Airport KPAO Palo Alto Arpt Of Santa Clara Co”
- now you could/should support your preflight planning by clicking onto the wedge in the upper right corner after the airport name and then analyze all data given under “info”, “atc”, metar”, and “links”
- then zoom into the airport
- set the mouse over the wanted “Parking lot” and read that position in the upper right corner of the screen
- type those long/lat values into the field below and also the wanted heading of the plane while parking
- Network: Those data you have already predefined on the Base-Page. But in case you have network-problems (may be due to many PC's on a home-network with even more LAN-cards) you may specify here your actual IP-Adress.
- WARNING: When saving these settings and reloading them again, FGRun might replace the given IP-Nr. by the PC-name. As of March 2009 you then have to replace that again with the IP-Nr. So use it only if you have to - first try it by adding nothing between the ",,". Keep it as "in,10,,5000".
- If you need to define the unique IP-Address, open a command-window and type
|OS||to type||cap.||returned values|
|Linux||ifconfig||eth0||Link encap:Ethernet HWaddr 00:1d:92:80:a6:ab|
inet addr:192.168.178.23 Bcast:192.168.178.255 Mask:255.255.255.0
|Windows||ipconfig /all||et||Physikalische Adresse . . . . . . : 00-16-E6-40-AB-BF
- 192.168.178.23 (or 20) is the number you would have to input between the two commas. Be very careful and double-check that you do not mistype “.” and “,”!!
- You do need a "generic" line as shown, because this defines the interface between FlightGear and FGCom.
- To input a new line: Start by selecting “generic” in the field “Protocol”. Then hit “New” and define the rest as shown.
- Editing an existing line: Start by clicking onto the existing one, then change as required.
- Deleting an existing line: Click onto the line to be deleted, then hit "Delete"
- For fgo or the command line add --generic=socket,out,10,localhost,16661,udp,fgcom to the command line options
- You do need a "generic" line as shown, because this defines the interface between FlightGear and FGCom.
- Avionics: let us define:
|Nav1:||114.10||San Jose VOR|
|ADF:||379||Brijj, beacon at SF|
- And activate DME to Nav1
- There is no field to input COM-radios, but remember them for setting them later manually:
- Here you can define any presetting for any values in the FGFS. See e.g.: File > Browse Internal Properties in the FlightGear menu.
- I personally do not want the plane to start rolling without me telling it to. So I set the parking break as default at startup.
- Input a new line: Just hit “New” and type your string.
- Edit a line: Be sure first to click onto an existing item and then edit this “Property”
- Delete a line: Click onto the line to be deleted then hit "Delete"
- Hit “OK” → “Run” and watch FlightGear starting. If screen-place allows you may want to pull the shown "FGFS Report-Window" to the side and watch how busy your PC is while loading the other multi-player models.
Open a command-window and change into the directory in which FGCom was installed (probably the same as FlightGear) and start FGCom. You must decide what server you want to use! Since Oct.2012 there are 2 FGCOM-servers available:
- The original: fgcom.flightgear.org.uk
- A new one: delta384.server4you.de
Due to technicalities it is not possible to speak from 1 server to the other - so try one and change if you notice that your friends are using the other.
So insert the server-address after a "-S" (watch: The "S" must be a capital!):
|Linux||fgcom -Sfgcom.flightgear.org.uk||"-Sfgcom..." with capital "S"|
|Linux Git|| cd ~/fgfs
|for this “Git complete” you do not need to specify the server address, because it is embedded in the script-file.|
|Windows||cd 'C:\Program Files\Flightgear\win32'
|"-Sfgcom..." with capital "S"|
For the following test position this command-window somewhere, where you can monitor it throughout the test.
The first response should be:
/fgcom - a communication radio based on VoIP with IAX/Asterisk (c)2007 by H. Wirtz <firstname.lastname@example.org> Version 1.2.2 build 206M Using iaxclient library Version SVN 206M Successfully parsed command-line options. Reading list of airports...done. Initializing IAX client as guest:email@example.com
If your printout up to that line is different go back to chapter Test the basic function
|1) If, due to a prior flight, COM1 was set to anything else but 118.600 (e.g. to 119.650) you will see the following 2 lines added to the initialization of the FGCom-window:|
Selected frequency: 119.650 Call rejected by remote
Instead of “119.650” there will be shown the last used frequency. In this case the source of the nearest ATC-Freq. 119.650 is more than 50km away from your actual position of the airplane, so FGCom rejects a connection to it. If the last frequency used would have been within 50 km you get an indication very similar to the next item.
|2) Switch COM1 to 118.60 (needed at Palo Alto):|
Selected frequency: 118.600 Hanging up call 0 Airport Palo Alto (KPAO Tower at 118.600 MHz) is in range ( 0.6 km) Call 0 accepted Call 0 answered Airport Palo Alto (KPAO Tower at 118.600 MHz) is in range ( 0.6 km)
|This last line will be repeated according the to time span you defined in the “Input/Output” command “--generic=socket,in,10,,5500,tcp”, you may change that value later according to your preferences.|
3) Press your PTT (PushToTalk on space-bar and joystick, as available):
[SPEAK] unmute mic, mute speaker [LISTEN] mute mic, unmute speaker [SPEAK] unmute mic, mute speaker [LISTEN] mute mic, unmute speaker
|Only in between “SPEAK” and “LISTEN” you are able to talk to others.|
Now lets set/verify the other Radios:
4) Pressing Upper+Space will switch to the next radio: NAV1
Radio-Select: NAV1 Selected frequency: 114.100 Hanging up call 0 Call rejected by remote [LISTEN] mute mic, unmute speaker
|Compare this to the NAV2 indication 2 steps later: something is wrong – and it wasn't your fault: Although this NAV is valid (see ...FGFS/data/Airports/apt.dat.gz), it is missing in the FGCom listing .../FGCom/positions.txt. I encountered this problem several times, as well for Airports as also for VOR's. If this happens with your most beloved airport you can add those missing data with a text-editor. But before changing be sure to save the original data somewhere - just in case!|
5) Pressing Upper+Space once more switches to COM2
Radio-Select: COM2 Selected frequency: 120.500 Airport San Francisco Intl (KSFO TWR at 120.500 MHz) is in range (29.1 km) [LISTEN] mute mic, unmute speaker Call 0 accepted Call 0 answered
|That looks OK: San Francisco is about 29 km away|
watch the “km” instead of miles!
10 km = 6.2137 mi
6) Pressing Upper+Space once more switches to NAV2
Radio-Select: NAV2 Selected frequency: 115.800 Hanging up call 0 Airport SAN FRANCISCO VOR-DME (SFO VOR at 115.800 MHz) is in range (28.5 km) Call 0 accepted Call 0 answered [LISTEN] mute mic, unmute speaker
|And Yes: The SF VOR is just a little closer than the airport(center)|
7) Pressing Upper+Space once more brings back COM1:
Radio-Select: COM1 Selected frequency: 118.600 Hanging up call 0 Airport Palo Alto (KPAO Tower at 118.600 MHz) is in range ( 0.6 km) Call 0 accepted Call 0 answered [LISTEN] mute mic, unmute speaker
8) Lets us start and continue flying in the direction about 130°:
Airport Palo Alto (KPAO Tower at 118.600 MHz) is in range ( 0.4 km) Airport Palo Alto (KPAO Tower at 118.600 MHz) is in range ( 0.2 km) Airport Palo Alto (KPAO Tower at 118.600 MHz) is in range ( 0.7 km) Airport Palo Alto (KPAO Tower at 118.600 MHz) is in range ( 1.3 km) Airport Palo Alto (KPAO Tower at 118.600 MHz) is in range ( 1.9 km) Airport Palo Alto (KPAO Tower at 118.600 MHz) is in range ( 2.4 km)
|notice that you first come closer (to the center of the airport) and after that getting away|
9) Let's switch to COM2 (San Francisco) and watch:
Radio-Select: COM2 Selected frequency: 120.500 Airport San Francisco Intl (KSFO TWR at 120.500 MHz) is in range (37.8 km) Call 0 accepted Call 0 answered [LISTEN] mute mic, unmute speaker Airport San Francisco Intl (KSFO TWR at 120.500 MHz) is in range (38.6 km) Airport San Francisco Intl (KSFO TWR at 120.500 MHz) is in range (39.5 km) .. Airport San Francisco Intl (KSFO TWR at 120.500 MHz) is in range (49.7 km) Hanging up call 0 Radio-Select: NAV2 Selected frequency: 115.800 Call rejected by remote [LISTEN] mute mic, unmute speaker
|That means: at about 50KM we are getting out of range and thus the on COM2 active SF getts terminated. Notice that also the inactive NAV2 gets terminated, because it exceeded the allowable range at about the same time!|
10) You could turn now and watch the opposite: At about the same distance those two will become active again (automatically, if you did not change the settings).
If you got here without any (technical) problems your FGCom is fully functional. Have fun when using it.
There are basically three types of FGCom-usage:
- Normal usage at airports: i.e. You set your radio to the airport as usual. Thus you are set up for the usual ATC-(keyboard)-procedures (either through the "'" (UpperCase#) and/or the Chat-Menus). In addition you then can talk to anybody in a radius of about 100 km (about 54 miles) around the airport, may that be friends, a maintained FGCOM-ATC/Twr-Operator, airport utilities, etc.. Be aware that as of April 2009 only very few planes are using the FGCOM for ATC-purposes - thus you should always use the ATC-Chat "keyboard"-procedures to announce arrivals/departures/taxiing etc. in addition. (We hope that may change in some future!)
- The AirToAir frequencies (122.75 and 123.45) are ideal for all Multiplayer events. They are without any range-limitations - and not yet "overcrowded!). Also when traveling you might want to listen on the 122.75 for others who want to contact you (or reverse). When there is much "talk" on the 122.75 you might just arrange with your partner to switch to 123.45 - and return to 122.75 afterward. As of April 2009 the 122.75 is already operational for this application, the 123.45 will follow soon. You may try from time to time if this limitations still exist.
- The Echo-Test frequency 910.00 to test your sound settings
- Finally you can manipulate the frequency-tables (positions.txt in your FGFS/FGCOM local directory) and define an own frequency for special events. e.g. a Flight-School at one airport with maybe multiple student-groups. Of course those are local manipulations on your own PC, which you have to agree on with your (planned to be) partners in advance.
Tips and Tricks
Airport missing in FGCom:
In case your favorite airport does not show up in the FGCOM (command-window), although you can tune your COMM to it, you can add it to your data-file “positions.txt” in your fgcom directory. See e.g. the line
KSFO,120.500,37.616630,-122.385478,TWR,San Francisco Intl
You can add extra lines for any locations you want. e.g.: (watch the separation comas)
apt-code = DUMY (a "dummy" or your favorite, but missing, airport code) KHz = take it out of your “FGFS-home/data/Airports/apt.dat.gz” or just take one of which you are sure that you do not need it in the FGFS-reality (notice that several Airports (far apart) use same frequencies! long/lat = take out of the Mpmap (or Google Map) type = whatever name = whatever
(of course those definition are only known to your own PC and last only until the next data update!)
If you edit Textfiles (e.g. Radio-listings) or xml-files you might not see line-endings when using your standard editor.
- For windows you can use "WordPad"
- For Linux the "gedit" works fine
Copying-Printing this WIKI-Page
If you absolutely want to have a local copy of this on your PC or need a hard-copy, then:
- to copy:
- select in the Browser-Menu: "File" --> "Save Page as.. "
- to print:
- go to the printable version.
- Then I suggest: Menu --> File --> "Page Setup": Set to "Landscape" --> "Apply"
- before printing I recommend: Menu --> File --> "Print Preview" and you see those many many pages!
- If you really want to wast that paper: Menu --> "File" --> "Print" and it will print on your favorite printer
Joystick compatibility between Operating Systems:
See Joystick for the main article about this subject.
You may use the same joystick-definitions across all Operating-Systems: But you may need to change the assigned numbers - your joystick-vendor might have done that for you already. Check e.g. (Unix, Mac, Win having assigned different "numbers"):
<axis> (instead of the usual <axis n=”3”> ) <desc>Mixture</desc> <number> <unix>3</unix> <mac>5</mac> <windows>5</windows> </number> <binding> <command>nasal</command> <script>controls.mixtureAxis()</script> </binding> </axis>
Assign PTT to joystick
If you want to assign the PushToTalk function to your joystick, add the following (for n you have to find your own number!)
<button n="x"> <desc>PTT - Push To Talk</desc> <binding> <command>nasal</command> <script>controls.ptt(1)</script> </binding> <mod-up> <binding> <command>nasal</command> <script>controls.ptt(0)</script> </binding> </mod-up> </button>
Helpful internet adresses
Especially for multiplayer events you should define all times in the internationally used GMT (Greenwich Meantime). Just pick up your deviation from GMT and memorize it. If everybody does it, we could avoid a lot of misunderstandings.
- Decimal to Degree http://www.hbnweb.de/mathematik/grad-dezimal.html
- Some programs need Decimal Lon/Lat values, others the Degrees/Minutes/Sec. Just convert it.
- Some programs need Decimal Lon/Lat values, others the Degrees/Minutes/Sec. Just convert it.
- Miles, km, feet, etc. etc. ...: http://www.convertunits.com/
- If like to avoid troubles (like NASA lost a satellite because of it) just look it up.
In case of problems over the internet you might check that the the following ports are allowed:
1314 TCP if the Festival-Server is used for Text/Sound 2005 UDP Vcp-Stream 4569 UDP FGCom VoIP, (Inter-Asterisk eXchange) 5000 UDP in/out Multiplayer (VPN Sftw.) 5001 UDP Enable HTTP-server 5002 UDP Enable property server 5003 UDP Enable Screen-Shot services 5004 UDP (may be used as a spare) 5505 UDP Terra Sync 16661 UDP FGCom listening to FGFS, usually “local host” only
Also consider that some modern modems do already provide a firewall. If in addition to that you use a local firewall in your PC, than you might expect an unhealthy competition between those two concurrent firewalls. In case of problems you should deactivate one of those (usually the one inside the PC, especially if several PCs are connected via that modem).

The latest SVN release at this time is the r149 which does not compile due to a constant that is not defined (STL_STRING). Such constant appears at line 57 in the file src/fgcom_init.cpp which is: #include STL_STRING
I guess that such constant must point to the STL library include file but I am not sure. I revert to the r148 SVN version which successfully compiles.
Command to get such version is: svn co -r148 svn://svn.dfn.de:/fgcom/trunk fgcom-r148
- 19 June, 2008: Currently the server is down due to hardware problems. It is unknown when the service comes back because he currently has no time to fix the problems.
- 22 November 2007: Due to heavy development at this time there may be some differences between the information on the web pages and the installation. Please follow the discussions on the FlightGear development list!
