B64D EQUIPMENT FOR FITTING IN OR TO AIRCRAFT; FLIGHT SUITS; PARACHUTES; ARRANGEMENT OR MOUNTING OF POWER PLANTS OR PROPULSION TRANSMISSIONS IN AIRCRAFT
Description
B64D covers aircraft equipment, systems, and components integrated into or mounted on aircraft structures, including interior fittings, safety gear, and propulsion system installations. This subclass encompasses flight suits, parachutes, landing gear arrangements, fuel systems, hydraulic systems, electrical systems, environmental control systems, and the mechanical or structural mounting of engines and transmission systems within aircraft. It also includes aircraft furniture, cargo handling equipment, and life-support apparatus designed for aircraft use. Related airframe design and aerodynamic features are covered separately under B64C, while power plant designs themselves are classified under B64C or relevant mechanical/engineering classes.
