EVENTS: 1. Turned off all longitudinal control loops except total energy to throttle. Elevator was held fixed at -5 deg TE up. 2. Under the degraded conditions, the altitude tracker was assisted by an airspeed damper. 3. The addition of airspeed damper to the altitude tracker was beneficial in keeping the airspeed from diverging. However, the performance was still not as good as TECS. 4.
