🔍 Key Concepts

• Definition of GMDSS Sea Area A1 under SOLAS and ITU regulations • Role of VHF-DSC (Digital Selective Calling) in distress alerting • Difference between ordinary VHF voice range and continuous DSC watch at a coast station

💭 Think About

• Ask yourself: What is the formal, regulatory definition of Sea Area A1? Is it based on simple VHF voice range, or something more specific? • Consider which type of shore station capability is required for automatic distress alerting on Channel 70. • Look at the options and identify which ones talk about general VHF range versus those that mention a specific DSC function.

✅ Before You Answer

• Verify which option mentions a coast station (not just any radio station) that maintains a continuous DSC watch on VHF Channel 70. • Confirm that Sea Area A1 is defined by coverage from shore-based VHF-DSC rather than the presence of a particular national service (like the U.S. Coast Guard) or public correspondence only. • Eliminate any choice that does not clearly include both: a coast station and continuous VHF-DSC capability.
