Mar 01, 2000, 00:46 (0 Talkback[s])

The Flight Gear Flight Simulator project is a free, open-source, multi-platform, cooperative flight sim development project. Source code for the entire project is available and licensed under the GPL.

Flight Gear version 0.7.2 is now available for download. This new version also requires you to download version 0.7.2 of the base package.

For more information, please visit the Flight Gear web page at:


Here is a summary of the changes for version 0.7.2:

  • Lots of code reorganizations
  • Build requires plib-1.1.x
  • Build requires SimGear-0.0.x (Available in the same place as the FlightGear source)
  • LaRCsim/c172 is now the default aircraft model.
  • Added flaps support to control model.
  • Lots of updates and tweaks for the LaRCsim/c172 model.
  • Use a more standard texture/blend mode combination for sun/moon halos to avoid render path that's not supported by all cards/drivers.
  • Change reported speed on hud from V_equiv_kts to V_calibrated_kts
  • Instrument panel rewrite by David Megginson. This isn't quite as flashy as the first pass, but is much more functional, plays much better with opengl, and it should be relatively easy for someone with graphical skills to make it look more spiffy.
  • MacOS fixes contributed by Darrell Walisser.
  • Many JSBsim updates.
  • Added a screen snapshot facility (F3).
  • Added a load/save state function contributed by David Megginson.
  • Added support for various I/O protocols and channels so that flightgear can communicate with itself and other programs through a variety of means.
  • Bug fix: The aircraft model used for external views was being included in the height above terrain check so when the view position and the aircraft model collided the current altitude kept getting pushed up to compensate, but of course the aircraft model would get pushed up as well because it tracks the current aircraft position and orientation. Thus you had a never ending cycle ...
  • Oliver's multiplayer network code now moved to his own subdirectory: NetworkOLK
  • Added simulated cloud puffs as we pass through the cloud layer.
  • Cleaned up some memory leaks occuring between ssg and flightgear.
  • Update to Christian's weather data base code.
