Question 1 of 27070

Vessels operating in which sea area(s) are required to carry either Inmarsat or HF equipment or a combination thereof under GMDSS?

🔍 Key Concepts

• GMDSS sea areas (A1, A2, A3, A4) and how each is defined • Which areas are covered by Inmarsat satellites versus areas that must rely on HF (High Frequency) radio • How SOLAS GMDSS carriage requirements change as you move farther from shore

💭 Think About

• First, recall which GMDSS sea area is defined specifically in terms of Inmarsat satellite coverage (excluding A1 and A2). Which area is that? • Think about the polar regions where Inmarsat coverage is poor or absent. Which sea area is that, and what equipment is emphasized there? • Eliminate any sea area where only VHF-DSC (short-range) equipment is required, since the question is about Inmarsat or HF or both.

✅ Before You Answer

• Verify the definition of Sea Area A1 (range and primary equipment type) to see if Inmarsat/HF is required there. • Verify which sea area is defined as "within Inmarsat coverage" and what equipment options are allowed there. • Verify which sea area is outside Inmarsat coverage (polar) and note that this area must have HF, not "either Inmarsat or HF".
