🔍 Key Concepts

• GMDSS maintenance options under SOLAS (at-sea, shore-based, duplication of equipment) • Role and responsibilities of a GMDSS maintainer versus a GMDSS radio operator • Who is permitted to perform or supervise at-sea maintenance and repairs of GMDSS equipment

💭 Think About

• Look at each choice and ask: does this describe a requirement that is always true under the at-sea maintenance option, or does it add a restriction that the rules do NOT actually impose? • Focus on the relationship between the GMDSS maintainer and the person with primary responsibility for distress communications: are they allowed to be the same person, or are they required to be different? • Consider whether the rules require every single at-sea adjustment or repair to be done only by a licensed maintainer, or whether there is some flexibility

✅ Before You Answer

• For each option, mentally compare it with the actual GMDSS provisions in SOLAS and FCC rules about at-sea maintenance and who may serve as maintainer. • Pay close attention to any words like "may not" or "must" that introduce absolute prohibitions or requirements—these are common places where false statements are hidden. • Verify whether there is any rule that forbids the same individual from holding both the GMDSS maintainer role and the operator with primary distress responsibility role.
