The FlightGear development team is delighted to announce the v2017.1 "Bergen" 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: Accurate buildings from OpenStreetMap, voice synthesis of tutorial instructions, improved rendering of Earth from orbit, and a more realistic blackout/redout system.

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 modelling, a flexible and open aircraft modelling 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.

Environment Rendering

  • For rendering views from orbit, Earthview 2.0 is now available, with support for normal maps, better upper atmosphere edge, cloud relief shader, improved dawn zone, horizon estimation and improved resource management.

Performance

  • Canvas performance has been improved.
  • Support for SIMD operations added, improving performance on some architectures.
  • AI performance has been improved.

Usability

  • Bergen Airport, Flesland (ENBR) in Norway is the default airport for this release.
