Which flight control surface on the DA20-C1 primarily controls roll (bank)?

• A. Ailerons
• B. Rudder
• C. Elevator
• D. Trim

Answer: (A)

Roll is controlled by the ailerons, the hinged surfaces on the trailing edges of the wings. When you move the control wheel, the ailerons move in opposite directions—one wing’s surface goes up while the other goes down—creating a difference in lift that makes the airplane roll toward the lower wing. The rudder on the vertical tail handles yaw, turning the nose left or right to help coordinate turns. The elevator on the horizontal stabilizer changes the nose pitch (up or down). Trim is for holding a chosen attitude with less control pressure, not for initiating roll.
