Abstract
A method of reducing drag of a leading edge device having first and second flow surfaces includes coupling the first flow surface to an airfoil and coupling the second flow surface to the first flow surface. The leading edge device may be moved between a retracted position and an extended position. The second flow surface may be positioned generally behind the first flow surface during at least a portion of the movement of the leading edge device between the retracted and extended positions.
