The position transmitters on the flying control hydraulic booster jack are known as "relais" jack sensors. These produce two-wire synchro information on stick position for the autostabiliser and autopilot.

There is a separate unit for each axis of flying control movement i.e. pitch, roll and yaw.

Each unit carries the necessary synchros for channels 1 & 2 and command and monitor computing. The units therefore incorporate design techniques aimed at minimising the common failure probability.

The units are mounted on the auxiliary hydraulic servo unit earth point and auxiliary servo extension is transmitted via a trailing link to the sensor input arm.
