This facility could be used in an emergency if the normal manual
steering system became defective, e.g. a broken steering quadrant
cable or control rod. It can also assist with diagnosis of faults in the
ram drive unit, drive pump or the rudder reference unit and its
linkage to the steering system since the autopilot normal course
control software is by-passed.

3.4.4 Power Steer Check
