Ailerons

[Ref Pilot’s Handbook of Aeronautical Knowledge, FAA-H-8083-25B Page 5-49, 6-3]

Ailerons

  • are attached to the outboard trailing edge (of each wing)
  • move in the opposite direction from each other
  • decreases the camber resulting in decreased lift;
    corresponding opposite deflection of the aileron on another wing increases the camber resulting in increased lift
  • differential in lift causes the aircraft roll about the longitudinal axis

Some jet transports have two sets of ailerons, a pair of outboard low-speed ailerons and a pair of high-speed inboard ailerons. When flaps are fully retracted after takeoff, the outboard ailerons are automatically locked out in the faired position.
