Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

The FlightGear development team is delighted to announce the v2019.1 release of FlightGear, the free, open-source flight simulator. This new version contains many exciting new features, enhancements and bugfixes.

Founded in 1997, FlightGear is developed by a worldwide group of volunteers, brought together by a shared ambition to create the most realistic flight simulator possible that is free to use, modify and distribute. FlightGear is used all over the world by desktop flight simulator enthusiasts, for research in universities and for interactive exhibits in museums.

FlightGear features more than 400 aircraft, a worldwide scenery database, a multiplayer environment, detailed sky modeling, a flexible and open aircraft modeling system, varied networking options, multiple display support, a powerful scripting language, and an open architecture. Best of all, being open-source, the simulator is owned by the community and everyone is encouraged to contribute.

FlightGear - Fly Free!

Weather

  • METAR interpretation: Change CAVOK visibility to 9999.0 metres
  • Fix for getting live weather

JSBSim

  • Added the ability to set up the starter and acceleration times of a turbine (parameters <n1spinup>, <n2spinup>, <n1startrate>, <n2startrate>).
  • The <integrator> filter can now be reset to 0.0 by setting its <trigger> property to a negative value.
  • The integration scheme of the <integrator> filter can now be chosen among "rect" (Euler), "trap" (Trapezoidal), "ab2" 2nd order Adams-BashForth and "ab3" 3rd order Adams-Bashforth
  • The following functions can now be used in <function>: floor, ceil and fmod. Their functionalities are the same than the corresponding C/C++ functions.
  • <function> now checks the number of its arguments.
  • New system component linear_actuator
  • Bug fix of Euler angles computations in FGMatrix33
  • Export the fuel density to the property tree
  • Added cyclic clipping for FCS components
  • Fixed a regression which prevented the wheels rotation speed to slow down while the gears were retracted
  • Added the ability to control the turbine engines spin down factor

Yasim

  • Yasim ground friction (stiction) changes

3D

  • Support for DDS Texture Cache
  • LOD: The scenery ranges for bare and rough are now deltas, to avoid overlapping values by user error.
  • Make star cutoff controllable at runtime
  • Compositor: New experimental rendering framework

AI

  • fgcommands "add-aiobject" and "remove-aiobject" for adding/removing objects to the AI subsystem.

Aircraft

  • The Boeing 777 received some updates:
    • You can save the amount of fuel between sessions (other useful functions will follow),
    • The radio stacks are now 8.33 kHz capable and you can store the frequencies between sessions,
    • The Fuel, Payload and Ground services dialogs and systems have received a lot of attention,
    • The 777 has now a realistic Fly By Wire (FBW) system,
    • Dynamic friction has been reduced, making braking action weaker and thus more realistic. Be aware that you might need a high autobrake setting on short runways (< 2000m), especially when heavy loaded or at altitude!
    • The new YASim static friction has been added.
    • Please request any new features on the official 777 topic on the forums, both Octal450 and Isaak are spending quite a lot of time on improving the 777, we are open to feature requests :)

Misc

  • Change screenshot filename to have date time
  • Map dialog draws heliports now
