🔍 Key Concepts
• GMDSS (Global Maritime Distress and Safety System) core objectives: distress alerting, SAR support, and dissemination of safety information
• Difference between mandatory GMDSS functions and other routine/secondary radio services (like normal bridge-to-bridge chatter)
• Role of MSI (Maritime Safety Information), SAR (Search and Rescue), and satellite alerting within GMDSS
💭 Think About
• Which options clearly focus on SOLAS-type safety functions (distress, SAR, MSI, and safety-related alerting) rather than routine operational communications?
• Does GMDSS exist primarily to support day-to-day traffic communications, or to ensure ships can send/receive distress and safety information anywhere, anytime?
• Look at each choice and ask: which items are specifically listed in GMDSS descriptions, and which are just general marine radio uses that existed long before GMDSS?
✅ Before You Answer
• Identify which functions are explicitly described in GMDSS overviews: distress alerting, SAR coordination/on-scene communications, MSI, and reception/relay of distress alerts
• Check whether Bridge-to-Bridge and general radio communications are core GMDSS requirements, or simply services that may still be provided by other equipment (like VHF Channel 13)
• Verify that the option you pick does not add specialized capabilities (like EPIRB homing/RDF) that are not listed as universal GMDSS communication functions for all ships
