The control surfaces of an aircraft include which of the following?

• A. Rudder, Ailerons and Elevator
• B. Fuselage and wings
• C. Engines and landing gear
• D. Flaps and payload bays

Answer: (A)

Control surfaces are the movable parts that shape the airplane’s flight path by altering the airflow around the wings and tail. The main trio used for primary flight control are the rudder, which controls yaw (left-right turning about the vertical axis) on the tail; the elevator, which controls pitch (nose up or down) on the horizontal tail; and the ailerons, which control roll (tilting the wings side to side) on the wings. By moving these surfaces, the pilot can steer the aircraft in three dimensions and execute coordinated turns. The other options aren’t correct because they don’t describe the complete set of primary flight control surfaces. The fuselage and wings are fixed structural parts, engines and landing gear relate to propulsion and support, and while flaps can adjust lift, payload bays are not movable surfaces.
