An airfoil having a trailing edge flap assembly comprising a flap member which in its stowed position is located above a fixed mounting structure. There is a rear pivot link connected at its lower end to the mounting structure and by its upper end to an aft portion of the flap. There is a forward slideway by which the forward part of the flap is mounted for longitudinal slide motion relative to the fixed mounting structure. The flap has a stowed position in the rear portion of the wing, and is movable rearwardly with substantial Fowler motion to an intermediate position for take-off, and movable further rearwardly to a fully extended position where the flap extends rearwardly and downwardly for take-off.
