FlightGear versions

v2.4 [Aug 23, 2011]
- A new head-up display (HUD) system
- An in-sim moving map
- ATC/ATIS improvements
- EICAS instruments are available on a selected number of aircraft
- Improved autopilots
- TCAS, works with AI and multiplayer aircraft, provides aural warnings for conflicting traffic and is also capable of driving a realistic traffic display. AI aircraft also respond to TCAS alerts and take evasive action
- Updates to the KLN89 GPS.
- Tankers now refuel with any callsign, and can enable/disable refueling in flight.AI system
- A standalone AI flightplan generator program
- Approaching aircraft now follow realistic approach trajectories
- Ballistic objects can be slaved to any AI object
- Improved AI ballistics behavior
- More communication / interaction between AI aircraft and ground. Support for multiple frequencies for AI/ATC interaction.
- Speed-up for AI traffic initialization by means of an aircraft usage statistics collection mechanismAI Traffic
