🔍 Key Concepts

• FCC GMDSS requirements for ships on international voyages (47 CFR Part 80) • Difference between FCC-required documents and IMO/IAMSAR operational guidance • Role of ITU (International Telecommunication Union) in maritime radio and GMDSS

💭 Think About

• Which organization (FCC, IMO, ITU, NGA) actually issues the regulatory requirements for radio stations on US ships? Focus on who controls the radio license and operating rules. • Look at each option and ask: Which items are specifically tied to radio licensing, frequencies, and station operation, versus general search-and-rescue or navigation guidance? • For a GMDSS radio inspection, what documents must you show the inspector that prove your station is authorized and operated under the correct radio rules?

✅ Before You Answer

• Identify which answer choices include Part 80 FCC rules and station licenses—both are central to FCC regulation of ship radio stations. • Check which manual title correctly matches the ITU publication used for maritime mobile services (wording matters: is it issued by ITU or IMO?). • Verify that every document in the chosen answer is related to radio communications regulatory compliance, not navigation or SAR search-planning references.
