Which of the following is not a type of pilot input control surface?

Wings are not classified as a type of pilot input control surface. Instead, they serve the primary purpose of generating lift for the aircraft.

On the other hand, ailerons, elevators, and rudders are all pilot input control surfaces that actively alter the aircraft’s attitude and direction. Ailerons are located on the trailing edge of the wings and help in rolling the aircraft. Elevators, found on the tail, control the pitch; that is, they help the aircraft climb or descend. Rudders, located on the vertical stabilizer, manage the yaw, allowing the aircraft to turn left or right.

Understanding that wings facilitate lift rather than actively control flight dynamics distinguishes them from the other three options, which directly respond to pilot input and affect the aircraft's orientation and movement in the air.
