Abstract
The gain of a stability augmentation system for an aircraft, particularly a helicopter, is automatically varied in accordance with the gross weight and deviations of the center of gravity of the aircraft. Gross weight and center of gravity are identified from in-flight measurements of collective and cyclic pitch stick position and airspeed. The gain of the stability augmentation system will not be changed during periods when the aircraft is being maneuvered.
