Abstract: A method and means are provided for increasing the aerodynamic efficiency of an airfoil employed by an aircraft. The method utilizes the primary flight control surfaces (11) (12) contiguous to the airfoil's trailing edge and relocates these devices to novel positions (21) (23) resulting in an expanded cord and enhanced camber for the aircraft wing (13). Self-adjusting push-pull rods (25) (60) replace conventional solid rods (24) where necessary in combination with a re-rigging of the flight control surfaces (11) (12) to predetermined positions (21) (23). Any voids created by this modification between the shared upper and lower fluid flow surfaces of the aircraft wing (13) and its flight control surfaces (11) (12) are eliminated through the installation of appropriate structure (40) or seal (43). Thus the aircraft wing (13) retains a unique geometric profile as a usual configuration.
