As it pertains to the automatic electric brake of a horizontal electro-mechanical anchor windlass, what statement is true?
AI Explanation
The correct answer is B) The brake is spring set and electrically released, and the brake automatically sets when electric power is removed from the electric drive motor.
This is correct because the automatic electric brake on a horizontal electro-mechanical anchor windlass is designed to be spring-set and electrically-released. When electric power is removed from the drive motor, the spring-loaded brake automatically engages to prevent the anchor from free-falling or running out. This is a safety feature to prevent accidental anchor deployment in the event of a power failure.
The other options are incorrect because they do not accurately describe the behavior of the automatic electric brake under loss of power. The brake does not automatically release when power is removed, as stated in options A and C. And the brake is not electrically set and spring-released, as stated in option D.
