A method and apparatus is provided for countering asymmetrical aerodynamic forces subjected onto an aircraft. Asymmetrical forces are counteracted by this invention automatically by selectively actuating force inducing elements in response detection of one of (a) differential longitudinal forces induced upon the aircraft by the engines and (b) undesirable rotation of the aircraft about longitudinal axis "c" of the aircraft. The force inducing elements of this invention function independent of primary control elements and other control surfaces of the aircraft.
