Ailerons are hinged panels on the rear section of each airplane wing. The two panels move in opposite directions — when the left aileron tilts up, the right one tilts down — which causes the airplane to roll sideways, allowing the pilot to steer left or right.
During the pre-flight check, the ground crew tested both ailerons to make sure they moved freely.
plural: both ailerons
The pilot pushed the stick to the left; the left aileron rose and the right one lowered.
opposite movement: left rises / right lowers
Ice buildup on the ailerons can make an aircraft dangerously hard to control.
On the Boeing 737, ailerons work with spoilers to help the plane bank during turns.
When a cable snapped, the right aileron stopped responding to the captain's controls.
用法筆記
Ailerons always come in pairs — one on each wing. They move in opposite directions to make the aircraft roll. Do not confuse with flaps, which extend on both wings together to increase lift during takeoff and landing.
