Inflight loss of control (LOC), unintended departure of an aircraft from controlled flight, is regarded by the NTSB and the 25~(th) Joseph T. Nall Report from the AOPA Air Safety Foundation as a significant flight safety issue. Over 40% of fixed-wing general aviation accidents occurred because pilots lost control of their airplanes. NTSB and AOPA Air Safety Foundation have determined that takeoff and climb, landing, and maneuvering are the deadliest phases of flight for LOC accidents. A precipitating factor of LOC accidents may be a pilot's incorrect use of ailerons only to raise a lowered wing, rather than correctly applying top rudder pressure combined with appropriate aileron use. "Top rudder" may be defined as deflecting the rudder in the direction of the raised wing. For example, while banked 45° to the left, the right wing is raised or pointed upward; pressing the right/top rudder pedal deflects the rudder in the direction of the raised wing (Fig. 1).
