🔍 Key Concepts
• GMDSS radio log requirements under SOLAS Chapter IV and 47 CFR/ship station practices
• Difference between Distress, Urgency, and Safety communications and routine traffic
• Required tests and checks (pre‑voyage, pre‑departure, daily/weekly) of GMDSS equipment and whether they must be recorded
💭 Think About
• For each option, ask: Does SOLAS/GMDSS actually require this specific information to be written in the radio log, or is it describing something done in practice but not strictly required?
• Compare how the rules treat Distress/Urgency/Safety messages versus ordinary routine traffic. Which categories are specifically called out as needing entries?
• Think about which GMDSS equipment tests are required (for example, DSC, EPIRB, SART, NAVTEX, Inmarsat) and whether regulations say the results of these tests must be logged.
✅ Before You Answer
• Check which of the following MUST be in the radio log: tests of equipment, Distress/Urgency/Safety communications, and routine MF/HF and Inmarsat‑C traffic.
• Verify whether Safety messages on VHF are treated differently from Safety messages on other bands in logkeeping rules.
• Confirm if any answer choice is simply a restatement of multiple correct requirements, or if it incorrectly adds or omits something that the rules specify.
