  • Apparatus and method for controlling aircraft, particularly remotely-controlled aircraft
    Patent number: 4964598
    Abstract: A remotely-controlled aircraft comprises a sensor for sensing the actual rate-of-turn of the aircraft and for generating a rate-of-turn signal proportional thereto, which signal, inherently also proportional to the actual bank-angle of the aircraft, is applied to the aileron drive as a negative feedback signal with the bank-angle command signal to thereby stabilize the bank-angle of the aircraft. The aircraft includes a further sensor for sensing the actual rate-of-climb of the aircraft and for generating a rate-of-climb signal proportional thereto, which latter signal, inherently also proportional to the actual pitch-angle of the aircfaft, is applied to the elevator drive as a negative feedback signal with the pitch-angle command signal to thereby stabilize the pitch-angle of the aircraft.
