Question 113General Subjects - 1st Asst/Chief

The correct answer is D. The automatic hydraulic brake of a horizontal electro-hydraulic anchor windlass is spring set and hydraulically released. This means that the brake is normally engaged (set) by a spring, and it is hydraulically released when the pump is operating. If the pump is brought to zero stroke or there is a loss of servo power hydraulic pressure, the brake will automatically set due to the spring action, stopping the anchor windlass. The other options are incorrect because they do not accurately describe the behavior of the automatic hydraulic brake in this type of system. Option A and B describe the brake as being the opposite of what it actually is (hydraulically set and spring released), while option C describes the brake as automatically setting when it should be releasing.
