🔍 Key Concepts
• GMDSS basic capabilities: distress alerting, alert reception, SAR (search and rescue) coordination, and general safety communications
• Maritime Safety Information (MSI): what it is (navigational warnings, weather, safety info) and whether GMDSS requires the ability to receive it or send it
• Difference between general communications, distress/safety communications, and locating signals (homing to the scene of distress)
💭 Think About
• Ask yourself: What are the core safety-related things every GMDSS ship must be able to do, regardless of sea area? Which option lines up best with those core functions?
• Which is more important from a regulatory perspective: being able to send MSI to others, or being able to receive MSI broadcast from shore?
• Look for the option that combines distress alerting, safety information, and communications with rescue authorities, not just ship-to-ship or bridge-to-bridge traffic.
✅ Before You Answer
• Verify in GMDSS references that the system must be able to transmit AND receive distress and safety communications, including distress alerts and SAR traffic.
• Check which functions explicitly include Maritime Safety Information (MSI) reception, rather than originating MSI for others.
• Confirm that locating signals (like those from SARTs or EPIRBs) are part of the required capabilities related to search and rescue, and see which choice uses them in a realistic way.
