Abstract
A multi-segment flap fence is incorporated into the wing such that a lower fence structure is attached to the underside of the fixed wing, an upper fence structure is attached to the main flap (e.g., at the outboard end). The two flap segments are configured to slideably articulate with respect to each other when the flap is extended to form a composite flap fence having an area that is substantially equal to the sum of the surface areas of the upper and lower flap fence structures. In one embodiment, the area of the upper fence is less than that of the lower fence.
