State Machine Parsing

Stuart has been finding the autopilot state machines absolutely fantastic for building complex autopilot logic for the FG1000. Thanks James!

Stuart has just committed a number of improvements to the state machine loader so that it will check for the correctness of the state machine at loading time and refuse to load incomplete state machines. Previously it would load malformed state machines, and then the sim would crash when it hit invalid states or transitions.

Now it will produce an error message indicating the state machine that is in error and the problem. In combination with Debug->Reload Autopilot this makes building a state machine much faster.

The downside of this is that if you've got an incomplete state machine, FlightGear will now refuse to load it.[1]

Updated aircraft


The Robinson R22 helicopter has been updated by HHS in FGAddon. So the turning direction and position of the tailrotor has been fixed, coefficients of gear adjusted and the new "stiction"-tag added which prevents skidding on the ground in idle. All others values matches the original values given in the Pilot Operating Handbook. Also the shaders on the exterior had been fixed. With the now added replay-system you can watch your flight over and over again. The R22-fdm belongs to the more realistic ones in FlightGear-FGAddon, and had been tested successfully in the past by real pilots like the user "rastafioul" and "ranger8" from the forum. The one who can master a Robinson R22, can master any other helicopter as well.

Ryan Navion

The Ryan Navion has been updated in FGAddon. Changes include: - re-addition of the KAP140 autopilot, bugfixes to the autopilot - HSI (KI252a) mechanical behavior added - KNS80 display fixed - RMI (KI227) mechanical behavior added - ADF (KR87) display fixed - Transponder (KT70) display fixed - Comm/Nav radio (KX165) behavior fixed - Electrical system fixed - Views fixed - Turn Coordinator fixed - Avionics fixed - Addition of a 'B' model with a 260hp engine


it0uchpods has began the FMGC rework, which will make the MCDU function for managing the flightplan. It is still in a testing phase, but is expected to be available shortly for testing. This approach completely removes the Route Manager, in favor of a fully custom designed flightplan management system, which will replace it.

Cessna 182S

The Cessna 182S is simulated in such a realistic way, that it many novice pilots have a lot of questions. So the article about Cessna 182S had been now extended with a FAQ, which should help to master this aircraft.

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.
