Convertiplane A convertiplane in popular usage is an aircraft that converts in flight to change its method of obtaining lift. The FAI define it more narrowly as an aircraft which uses rotor power for vertical takeoff and landing (VTOL) and converts to fixed-wing lift in normal flight. This is the definition used here.
