Question 1523 Deck Safety

The correct answer is C) 15 minutes on and 5 minutes off. The searchlight on a survival craft must be capable of operating for 3 hours continuously or 6 hours intermittently. The intermittent operation should be in cycles of 15 minutes on and 5 minutes off, as specified in C. The other options are incorrect because they do not meet the requirement of 6 hours of intermittent operation. Option A (5 minutes on and 10 minutes off) and Option B (10 minutes on and 5 minutes off) would not provide 6 hours of intermittent operation. Option D (15 minutes on and 10 minutes off) would exceed the 6-hour requirement.
