Patent ID: 7959111

Claim:
An AFCS (automated flight control system) for an aircraft, comprising: a receiving unit, the receiving unit receiving an angle of attack for the aircraft during at least one of: a climb of the aircraft and a descent of the aircraft; and a control unit, the control unit being communicatively coupled to the receiving unit, the control unit being configured for receiving the angle of attack from the receiving unit, the control unit being further configured for receiving an user-provided angle of attack, the control unit being further configured for comparing the user-provided angle of attack to the angle of attack received from the receiving unit, the control unit, based upon said comparison and during at least one of: the climb of the aircraft and the descent of the aircraft, being further configured for maintaining the user-provided angle of attack by separately controlling: an angle of incidence of the aircraft, the angle of incidence of the aircraft representing an angle between an aircraft wing chord and a longitudinal axis of the aircraft; a thrust of the aircraft; and a pitch angle of the aircraft, the pitch angle of the aircraft representing an orientation of the longitudinal axis of the aircraft.
