0 a part along the back edge of an aircraft's wing that can be moved to help the aircraft turn or to keep it level --
Aileron and flaps are piano-hinged to the bottom skin.
They carried differential ailerons and trailing edge flaps.
The wing is fitted with half-span ailerons and flaps.
The entire trailing edge consists of flaps inboard, out to about span with ailerons outboard which also drooped when the flaps were deployed.
Double ailerons of mixed wood-and-metal construction filled almost all the trailing edges beyond the engine cut-outs.
With no geometric washout applied, differential deflection of the ailerons was used to increase spin resistance.
The wings also incorporate washout, retaining aileron effectiveness at or just prior to the stall.
Early versions used wing warping for roll control, while later models used full-span ailerons.
