Concerning the operating mechanism of a controllable-pitch propeller, what statement is true?
If the hydraulic actuator is inboard or outboard, hydraulic oil pipes are located within the propeller shaft in either case.
If the hydraulic actuator is inboard or outboard, the blade rotating mechanism is actuated by a mechanical pull-push rod located within the propeller shaft.
If the hydraulic actuator is inboard, a mechanical pull-push rod is located within the propeller shaft. If the hydraulic actuator is outboard, hydraulic oil pipes are located within the propeller shaft.
