X-Plane is a flight simulation software initially launched by Laminar Research in 1995. Commercial desktop versions are sold for macOS, Windows, and Linux. In addition, Laminar Research also distributes FAA-certified versions for professional use. A mobile version has been available for Android, iOS, and webOS since 2009 as well.

Flight model

X-Plane implements an aerodynamic model called blade element theory.

Network flight

X-Plane can connect to other X-Plane instances via UDP or TCP for multiplayer flight simulation, networked multi-monitor X-Plane configurations or to plugins, such as Pilot Edge, which themselves communicate with other X-Plane instances.
