What are the four main control surfaces of an aircraft?

• A. Ailerons, Flaps, Rudder, Trim tabs
• B. Elevators, Ailerons, Rudder, Trim tabs
• C. Ailerons, Flaps, Elevators, Slats
• D. Wings, Fuselage, Ailerons, Elevators

Answer: (B)

The four main control surfaces of an aircraft comprise the ailerons, elevators, rudder, and trim tabs. Each of these surfaces plays a crucial role in controlling the aircraft's movement along its three axes. Ailerons are located on the outer portion of each wing and are responsible for controlling roll by allowing the wings to move up or down, facilitating bank angles for turns. Elevators are found on the tail section and control pitch, allowing the aircraft to climb or descend. The rudder, located on the vertical stabilizer, manages yaw, which helps in controlling the aircraft's directional heading. Trim tabs are smaller adjustments that can be set to optimize the control surfaces, minimizing pilot workload and keeping the aircraft stable in flight. This choice is accurate because it correctly identifies the primary surfaces used for maneuvering the aircraft in all three dimensions, while not including auxiliary surfaces or components that do not directly control flight.
