This invention proposes a rapid simulation method for the motion of an aircraft under cable constraint. The cable constraint model is transformed into distance constraints and constraint forces on the aircraft. Due to the mechanical property of the cable being under tension but not compression, the constraint force exists only in the direction of cable extension.

Furthermore, it can be used to calculate multiple motion states, including cable release, recovery, and towing.
