🔍 Key Concepts

• GMDSS Sea Area A3 coverage and typical equipment requirements • The three methods of meeting GMDSS equipment maintenance requirements: duplication of equipment, shore-based maintenance, on-board maintenance • Meaning of "partially meets" vs "fully meets" the maintenance requirement in SOLAS/GMDSS

💭 Think About

• Which options claim that a single method (like only on-board maintenance or only at-sea maintenance) completely satisfies the maintenance requirement? Is that consistent with GMDSS rules? • Look for the answer that combines more than one method (e.g., redundancy AND maintenance) and think about why SOLAS wants more than one layer of protection for A3 ships. • For each choice, ask: does this reflect SOLAS974/GMDSS structure, where you can comply with the maintenance requirement by using one method alone, or by using combinations that only partially meet the requirement?

✅ Before You Answer

• Verify in SOLAS and GMDSS guidance that there are three recognized ways to comply with equipment maintenance requirements. • Confirm that no single method is automatically assumed to be "full" compliance in all situations; some methods are treated as providing partial compliance that must be combined with others. • Check carefully which statement about shoreside maintenance and scheduled tests is correct in terms of whether it can partially meet requirements.
