Development news

FlightGear v2016.2 released

The FlightGear development team is delighted to announce the v2016.2 "Barcelona" release of FlightGear, the free, open-source flight simulator. This new version contains many exciting new features, enhancements and bugfixes. Highlights in this release include the Space Shuttle, ALS filters, a new HTTP TerraSync system, and improvements to our automatic ATIS.

A list of major changes can be found at Changelog 2016.2. FlightGear v2016.2 is available for a variety of operating systems from http://www.flightgear.org/download/.

Revamping TerraSync

Thanks to work by Torsten Dreyer, TerraSync now uses HTTP to fetch scenery. Some advantages to this method are is simpler code, requiring less space, and making it much easier to set up a TerraSync server.

Sound expressions

Erik Hofman has added support for XML expressions in the volume and pitch sections of audio configuration files.[1]

It works as follows:

  • If an expression is found in <pitch> or <volume> it gets processed and the rest is ignored.
  • If an expression was defined in a volume or pitch definition of a sound-section then all other volume or pitch sections containing a property are ignored.
  • Sections with <internal> are always processed so timed sounds are still available.

This way you can add volume and/or pitch sections with an expression before all other sections and keep backward and forward compatibility. But you could, for example, make the expression section more complex for newer versions of FlightGear.

For an example, see here

Cessna 172P

The Cessna 172P team has just created a new version of FlightGear's default aircraft, containing the latest developments from the last few months,[2] including:

  • Decreased rudder authority
  • Added propwash effect for 180 HP version
  • Improvements to the irradiance effect
  • Better oil dialog
  • Flap lever is now dragable and scrollable
  • Added normal map to wheels and other objects
  • Improvements to the heading indicator
  • Correct rudder pedal animation
  • Updated tutorial to Barcelona
  • Changed "Autostart" menu item to actually start the engine as well
  • Split instrument light knob into a knob that two knobs: one that controls the instruments, and one that controls the radio's

ICARO Laminar 13 MRX

There is a new aircraft in FGAddon — the Icaro Laminar 13 MRX. It is an advanced weight-shift controlled hanglider build by ICARO in the early 2000s.

The aim of this project is to provide a very realistic hang glider which shows all the specific properties of a real hang glider. In particular the unique flight dynamic behavior (compared to common aircraft) is focused on.

Paraglider updates

David Culp's paraglider has had major FDM and 3D model update. The FDM is now a true ram-air type. In addition, a small engine has been added and the parachute itself is now animated.

Note  As of June 2016, there is a bug prevents the paraglider from loading properly at FG 2016.2's default airport (Barcelona). Any other airport does not seem to cause a problem.

FlightGear logos

If you want some graphic elements for your FlightGear-related site (such as a hangar or YouTube channel), please feel free to visit FlightGear logos for a repository of logos. And if you have some art skills, please don't hesitate to contribute with your own design creations.


The FlightGear project always needs screenshots, which show features that were added since the last release. These should be of good quality, especially in content and technical image properties. It is therefore recommended to use the best viable filter settings (anti-aliasing, texture sharpening, etc.). More info at Howto:Make nice screenshots.
