Ailerons are controlled using which control device?

• A. Rudder pedals
• B. Flap lever
• C. Trim wheel
• D. Control wheel or yoke

Answer: (D)

Roll is controlled by the ailerons, the surfaces on the trailing edge of each wing that move in opposite directions to create differential lift and make the airplane roll about its longitudinal axis. The device you use to command that roll is the control wheel or yoke—rotating it left or right deflects the ailerons accordingly to produce the desired bank.

Rudder pedals control the rudder for yaw, not roll. The flap lever adjusts the wing’s flap setting to change lift and drag, and the trim wheel sets the aircraft’s attention to a steady flight without continuous pressure on the controls.
