Question 451 Deck Safety

The correct answer is D) 50 feet of clear deck. According to the regulations set by the US Coast Guard, the hoist area for a rescue helicopter should have a minimum radius of 50 feet of clear deck space. This is to ensure that the helicopter has enough maneuvering room to safely lower and raise the rescue personnel or equipment without any obstructions or potential hazards within the hoist area. The other options are incorrect because they do not meet the minimum requirements specified by the Coast Guard regulations. A 6-foot or 10-foot radius would be too small, while 25 feet, while larger, still does not provide the necessary 50-foot clearance recommended for safe helicopter hoist operations.
