Abstract:

A flight simulator includes a central processing unit and a flight simulation environment controlled by the central processing unit for simulating the flight of an aircraft. The central processing unit is programmed to observe a full fidelity model of the aircraft in flight so as to extract pilot inputs and aircraft responses at each of successive time intervals. The central processing unit is further programmed to calculate a damping and an undamped natural frequency of the aircraft from the extracted pilot inputs and aircraft responses and to simulate the flight of the aircraft by applying the damping and undamped natural frequency to a second order transfer function.
