A method and apparatus for the real time estimation of the location of the center of gravity in an aircraft using a linear estimation technique. The center of gravity estimate is used in the aircraft\s flight control system (12) to implement flight control laws that depend on the aircraft\s center of gravity. The center of gravity is initially estimated based on signals indicative of the aircraft angle of attack, flap setting, elevator position, and stabilizer position. The initial approximation is then refined by multiplying or dividing the center of gr...

A method of determining the location of an aircraft\s center of gravity in an aircraft flight control system that employs the aircraft\s center of gravity location for executing one or more control laws that establish the flight path of the aircraft, said method comprising the steps of: (a) obtaining signals from said aircraft flight control system that are representative of the aircraft angle of attack, flap setting, stabilizer position, effective elevator position, effective weight, and dynamic pressure; (b) adding the aircraft effective elevator posit...
