File Type 2 X-Plane Aircraft File
Developer by: Laminar Research Category: Data Files Format: Text

Aircraft file used by X-Plane, a realistic flight simulator for pilots and simulator hobbyists; contains data that describes the properties of the aircraft, such as engine power, flight physics, mass properties, and limits.

You can create an ACF file using Plane-Maker, which is a utility that comes with X-Plane. However, Plane-Maker does not enable you to create a 3D model, it is only used to determine the layout of basic aerodynamic shapes and properties of the aircraft. You can use the AC3D application with the X-Plane plugin to create a 3D model in the X-Plane OBJ format.

NOTE: Before version 10 of X-Plane, the ACF file contained aircraft data in binary format. It now contains data in text format.
