Abstract
In order to determine the location of the center of gravity of an aircraft in flight, an accelerometer is placed in the forward part of the aircraft and another is placed in the after part to produce signals representing the rotation of aircraft about an axis, preferably the yaw axis, through the aircraft center of gravity. The signals from the accelerometers are combined to produce a first signal having components that represent both motion of the aircraft and the location of the center of gravity along with a signal having a component representing the motion of the aircraft but substantially without a component representing the location of the center of gravity and these two signals are then combined to get a signal that represents the location of the aircraft center of gravity.
