Abstract
A wing flap assembly having a contoured upper forward surface portion of the flap being arranged to reduce adverse effects of a wake producing device, such as a landing gear or a flap track faring, positioned upstream of the slot, when the flap is in its highlift slotted position. The contoured area has a moderately greater slot gap width, and relatively sharper curvature at a nose end of the contoured flap surface portion to produce a desired pressure distribution where recovery begins at a further upstream location on the flap.
