🔍 Key Concepts
• GMDSS radio log requirements in 47 CFR and 46 CFR
• What types of communications MUST be logged (distress, urgency, safety, routine)
• Use of standard abbreviations and key letters in official logs
đź’ Think About
• Think about whether official radio logs are allowed to use standard, recognized abbreviations or if they must always be written out in full words.
• Consider if urgency traffic (PAN-PAN) is important enough from a safety and legal standpoint that it should be recorded in the logbook.
• Ask yourself: if both statements A and B were completely correct, would that match what you know about how carefully radio communications are documented on SOLAS/GMDSS ships?
âś… Before You Answer
• Verify whether standardized abbreviations (like distress signals, time formats, or prowords) are permitted in GMDSS logs.
• Confirm which categories of traffic are mandatory entries: distress (MAYDAY), urgency (PAN-PAN), safety (SECURITÉ), routine.
• Check if the regulations say that all significant safety-related communications must be logged, and whether urgency calls fall into that group.
