Basic? definitions? and? classification 3.1.1 rotorcraft rotary wing aircraft heavier-than-air aircraft that depends principally for its support in flight on the aerodynamical generated by one or more rotors 3.1.2 helicopter rotorcraft (3.1.1) that primarily depends on engine driven rotors for motion at all stage of flight 3.1.3 gyroplane autogyro gyrocopter rotaplane rotorcraft (3.1.1) whose rotors are not engine-driven, except for initial starting, but are made to rotate by action of the air when the rotorcraft is moving; and whose means of propulsion, consisting usually of conventional propellers, is independent of the rotor system 3.1.4 gyrodyne compound helicopter compound gyroplane rotorcraft (3.1.1) with a rotor system that is normally driven by its engine for takeoff, hovering and landing like a helicopter (3.1.2), and has an additional propulsion system that is independent of the rotor system
3.1.5 convertiplane aircraft which uses rotor power for vertical takeoff and landing (vtol) and converts to fixed-wing lift in normal flight Note 1 to entry: Convertiplanes may be divided into two broad classes, based on whether the rotor is fixed as in a helicopter (3.1.2) or tilts to provide thrust in forward flight, as a proprotor. a proprotor may be in a tilt rotor or tilt wing configuration. 3.1.6 tiltrotor aircraft rotorcraft (3.1.1) which generates lift and propulsion by way of one or more tiltable (rotating) powered propellers, or proprotors, mounted on rotating engine pods or nacelles usually at the ends of a fixed wing Note 1 to entry: Orientation of wings is fixed. For vertical flight, the rotors are angled so the plane of rotation is horizontal. 3.1.7 tiltwing aircraft aircraft with a wing that is horizontal for conventional forward flight and rotates up for vertical takeoff and landing 3.1.8 helicopter? configuration combination of features, defining main rotor (3.2.1) system, anti-torque system (for single rotor helicopter (3.1.9)), flight control system
