🔍 Key Concepts
• Distress, urgency, and safety signals used in marine radiotelephone (MAYDAY, PAN-PAN, SECURITE)
• The difference between distress (immediate danger to life/ship) and urgency (safety of a person or vessel, but not yet in grave and imminent danger)
• Which signal is used specifically for navigational or meteorological safety information
💭 Think About
• First, recall what situation requires the strongest call for help and which spoken word is used for that. Then, compare that with PAN-PAN.
• Think about whether PAN-PAN is more about the condition of a person or vessel right now, or general warnings about weather and navigation that might affect many ships.
• Match each radiotelephone priority word (MAYDAY, PAN-PAN, SECURITE) to its type of situation, then see which answer choice best fits the role of PAN-PAN.
✅ Before You Answer
• Be sure you can clearly define MAYDAY versus PAN-PAN in your own words before choosing.
• Verify which call sign is associated with general safety messages (like weather or navigation warnings) and which is for urgent but not yet life‑threatening situations.
• Confirm that the option you pick matches urgency about a specific person/vessel, not broad informational warnings, if that is what PAN-PAN is used for in your study materials.
