Autopilot
Available autopilot systems on the Learjet 35/36 aircraft include
the J.E.T. 200 or J.E.T. 530. The autopilot provides automatic
control and stabilization of the aircraft about the pitch and roll
axes. The mode of operation includes the ability to automati-
cally maintain desired altitude, pitch attitude or heading, and to
automatically capture and track localizer, glideslope, and VOR
signals.
The autopilot can be physically over-powered by the flight
crew; however, the forces can be quite high.
Aircraft with FC-200: Depressing the wheel master switch dis-
engages the autopilot and yaw damper, and interrupts the pri-
mary pitch trim.
Aircraft with FC-530: Depressing the wheel master switch dis-
engages the autopilot and yaw damper, and interrupts the pri-
mary and secondary pitch trim, stick pusher, puller, and nudger.
The autopilot is integrated with the flight director to automati-
cally control and direct aircraft flight.
Flight Director
The flight director system consists of:
Q
Collins FD-108 Integrated Flight System
Q
Collins ADI-85A Attitude Director Indicator
Q
Collins HSI-85 Horizontal Situation Indicator
Q
flight guidance control panel.
These components and information from navigation and
marker beacon receivers, the radio altimeter, and distance
measuring equipment provide an easily read display of aircraft
attitude, navigational situation, and steering commands. Steer-
ing commands enable the pilot to capture and fly selected
heading, radio courses, and an ILS down to decision altitude.
