Where are the ailerons located on the aircraft?

• A. On the tailplane.
• B. Located on the outboard trailing edge.
• C. On the leading edge near the fuselage.
• D. On the wing root.

Answer: (B)

The main concept is how roll is controlled and where those surfaces sit. Ailerons are the primary roll-control surfaces on airplanes, and they are located on the trailing edge of the wings. On the Growler, they sit on the outboard portion of the trailing edge—the outer section toward the wingtips. When you move the stick to roll, one aileron deflects up while the other goes down, creating opposite changes in lift that tilt the wings and initiate a roll. They aren’t on the tailplane (that’s for pitch and yaw), nor on the leading edge near the fuselage (leading-edge surfaces like slats or leading-edge flaps live there), nor at the wing root (the root is near the fuselage). So the best description is the outboard trailing edge of the wings.
