Abstract
A swept wing having a leading edge flap which in its deployed position forms a slot with the forward end portion of the wing. An elongate strip is positioned on the forward portion of the wing in a manner that when the flap is deployed to form the slot, this strip protrudes into the airstream that passes upwardly through the slot. This creates a stall condition in the area of the strip to produce the desired pitch characteristics for safe recovery from stall. In the cruise configuration, where the flap is positioned against the leading edge of the wing, this strip is aerodynamically concealed.
