FlightGear – a realistic open-source flight simulator.
FlightGear is an advanced, free flight simulator built by enthusiasts for enthusiasts. It delivers an impressive level of realism across cockpit instruments, physics, and navigation. FlightGear is open source and available for Windows, macOS and Linux – making it a great choice for hobby pilots, curious beginners, and hardcore sim fans.
High realism across the board
What sets FlightGear apart from many other free simulators is its level of realism. The cockpit instruments behave exactly as they do in real aircraft. Gyroscopic drift is accurately modeled, and even the magnetic compass responds naturally to motion and forces during flight.
The flight dynamics are based on advanced aerodynamic calculations, and the in-sim weather can be matched to real-world data. This gives you an authentic experience of flying under different conditions and at different times of day.

Tips for FlightGear
