Definition#
An aileron is a hinged flight control surface attached to the trailing edge of each wing, near the wingtip. When one aileron deflects upward and the other deflects downward, the aircraft rolls about its longitudinal axis.
Why It Matters Operationally#
Ailerons are the primary roll control. They enable turns and bank angle adjustments. Differential aileron movement and coupling with rudder prevents adverse yaw.
