A command signal input to the steering gear has initiated rudder movement for 20° right rudder. The follow-up mechanism at the beginning of the rudder movement will __________. Illustration GS-0123

Correct Answer: Option A — be in motion with a null input

As the rudder moves toward the commanded position, the follow-up mechanism tracks the movement. When the rudder reaches the commanded angle, the follow-up gear cancels the input signal to the variable stroke pump, returning it to a null stroke position to stop further movement, maintaining the desired rudder angle.
