What statement is generally correct regarding the maintenance requirements for ships under GMDSS?
Official USCG Answer & Rule Citation
Correct Answer: Option D — All of the above
SOLAS Chapter IV, Regulation 15, allows for a combination of methods to ensure equipment availability. Redundancy (duplication), qualified on-board maintenance by a licensed GMDSS maintainer, and formal shore-based maintenance contracts with scheduled inspections all contribute to meeting the overall GMDSS availability requirements for safety-critical radio installations on board.
