Which control surface is controlled by the control wheel (yoke) through a system of cables, pulleys, and other connecting devices?

• A. Aileron
• B. Rudder
• C. Elevator
• D. Flap

Answer: (C)

The control wheel moves the elevator through a network of cables, pulleys, and linkages, so your fore-and-aft inputs translate directly into pitch changes. The elevator sits on the horizontal stabilizer at the tail, and when it deflects up or down, it changes the tail’s aerodynamic force, creating a pitching moment that raises or lowers the nose. This is how you control climb, descent, and attitude in the vertical plane. The rudder is controlled by pedals for yaw, and flaps are operated by a separate control, while the ailerons are typically actuated by the yoke for roll, but the surface most directly tied to the wheel’s input through that cable-and-pulley system is the elevator.
