About

FlightGear allows you to control over 400 aircraft, small and large in a range of situations, types of weather, seasons, day and night cycle. This includes single-engine propeller aircraft, large 4-engine passenger liners, experimental aircraft, classic and vintage aircraft and helicopters. The FlightGear landscape covers the entire world and is downloaded as you fly. Visit any of the 20,000 airports with an accurate representation of airport buildings on many of the larger, international airports. Most popular flight control hardware, such as yokes and sticks are supported. Multiple monitor setup and multiplayer is also featured.
