What is defined as the area within the radiotelephone coverage area of at least one VHF coast station in which continuous DSC alerting is available as defined by the IMO regulation for GMDSS?

🔍 Key Concepts

• GMDSS sea areas (A1, A2, A3, A4) and how each is defined • The difference between VHF coast station coverage and MF/HF or satellite coverage • What continuous DSC alerting on VHF implies about range and equipment

💭 Think About

• Which GMDSS sea area is specifically linked to VHF radiotelephone/DSC coverage from at least one coast station, and usually has the shortest range? • Look at each option: which ones are satellite ocean regions, which one is defined by MF coverage, and which one is defined by VHF coverage? • Ask yourself: in which sea area are ships required (at minimum) to carry VHF-DSC equipment because they are expected to be within VHF range of a coast station?

✅ Before You Answer

• Verify the formal GMDSS definitions of Sea Areas A1, A2, A3, and A4 in IMO GMDSS regulations or SOLAS Chapter IV. • Confirm that Ocean Area Regions (AOR-E, AOR-W, POR, IOR) are related to Inmarsat satellite coverage rather than VHF coast stations. • Check which sea area’s definition explicitly mentions VHF coast station coverage and continuous DSC alerting.
