Instructional film about the benefits of multiplex autopilot rather than a single system autopilot. All very technical, obviously intended for industry experts 1960's

Aerial view of the British countryside, camera must be mounted on the undercarriage of an aircraft. The front wheel desends into view. Smith's aircraft. In 1956 Smith's of Cheltenham designed a new system for aircraft. The multi plex auto pilot. Laboratory, Simulated test of a fault in an aircraft system. The fault shows up on a graph. Diagram shows what would happen in the instance of a fault in a real aircraft if the fault occurred at 50 feet altitude. With no auto pilot the plane would crash, with single system auto pilot the pilot may have a chance to pull the plane out of desent and fly off. With multiplex auto pilot the aircraft would still land safely. Laboratory. 3 scaled down engines are tested. Dakota aircraft with Smith written on the side. Fault testing on the aircraft. Gyro, electric circuits, amplifiers. Triplex system. Aircrew inject a simulated fault into the aircrafts system. Narrator explains the aircrafts controls, very technical. Close up of various dials, knobs, buttons switches. Auto pilot. Dakota takes off. At 2000 feet they insert a fault into the system. Without the multiplex system the nose of the aircraft dips and the plane instantly looses 400 feet altitute, could be fatal. With multiplex the nose does not dip and the plane remains on course. Triplex or multiplex allow for complete safety. Laboratory. Electrical circuits. Aircraft lands safely.
