The Tornado Autopilot and Flight Director System was designed to provide automatic control of the aircraft in Pitch and lateral planes in a variety of operating modes. Included in the autopilot facilities are an Autothrottle which provides airspeed hold by means of thrust control and pitch auto-trim which continuously controls the pilot's stick to the pitch trim position.

The Autothrottle Actuator contains a d.c. motor which drives the splined output shaft via a 30:1 spur gear and an electro-magnetic engage clutch. A dual potentiometer geared to the clutch input provides feedback and monitoring information to the system.

This unit is red banded which indicates that it was probably a Qualification Test asset and was designed to Specification No. SP-P970162.
