fowler flap(redirected from Flap (aircraft))
Also found in: Wikipedia.
A type of trailing edge flap that moves out of the wings on tracks. These flaps increase the wing area, the chord, and the camber and help in boundarylayer control. They provide maximum additional lift. Fowler flaps are commonly used but have a complicated mechanism.
