The Feel Sensor produces a two-wire synchro signal as a function of the feel displacement from the zero feel force position for use in the electric trim system when the autopilot is operative . The unit is mounted on the artificial feel chassis.
The sensor includes synchros for channels 1 and 2 command and monitor computing lanes. Specialised design techniques are used to minimise the common failure probability.
Two of the four synchros have been removed from his unit, though their cut wiring is still present. Some of the inked markings on the remaining two synchros are difficult to discern - the labels have blackened in these areas.
