ABSTRACT:
A semi-automatic takeoff flight control system for automatically capturing a predetermined takeoff pitch attitude at a predetermined pitch rate during the aircraft takeoff rotation maneuver. In response to the manual rotation command from the pilot, control circuitry generates a pitch rate command to the elevator, limited to the predetermined pitch rate. As the craft rotates to an intermediate pitch attitude less than the desired predetermined takeoff climb attitude, circuitry is included to provide a pitch attitude command with regard to the predetermined reference attitude, which by virtue of rate, displacement, and integral control provides asymptotic capture of the predetermined reference attitude.
