From the developer:
The FlightGear Flight Simulator project (often shortened to FlightGear or FGFS) is an open-source, multi-platform, cooperative flight simulator development project. It also simulates space flight in Earth's orbit.
FlightGear's flight dynamics engine (JSBSim) is used in a 2015 NASA benchmark to judge new simulation code to the standards of the space industry. It's used professionally for research and development, as well as non-professionally.
You may want to check out more software, such as FGo!, TaxiDraw or ModelConverterX, which might be similar to FlightGear.
