Which two control surfaces are used together to perform a coordinated turn?

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

Answer: (C)

Coordinating a turn relies on combining roll with yaw control. The ailerons bank the airplane by tilting the wings, which makes lift push the aircraft into a turn. But deflecting the ailerons alone tends to cause adverse yaw, so the rudder is used to counter that yaw and keep the nose aligned with the flight path. This pairing—using the ailerons to roll and the rudder to coordinate the turn—keeps the aircraft from slipping or skidding and maintains a smooth, coordinated entry and exit from the turn. Elevators manage pitch and aren’t part of the coordination of the turn, flaps mainly alter lift and drag, and a canard setup isn’t part of standard coordination in most airplanes.
