🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) regulatory structure in the U.S. • Difference between FCC radio regulations (Title 47 CFR) and U.S. vessel inspection/safety regulations (Title 46 CFR). • Where requirements that apply specifically to U.S.-flag vessels (as opposed to all radio stations) are normally found.

💭 Think About

• Ask yourself: when the question says "specifically to U.S.-flag vessels," is it pointing you toward general radio rules, or toward rules tied to U.S. vessel inspections and certifications? • Look at which answer choices reference Parts of Title 47 CFR (FCC radio rules) versus other documents. Which one is actually the main U.S. regulatory home for GMDSS carriage requirements? • Consider what CCIR documents usually contain. Are they U.S. domestic regulations, or international technical recommendations? How does that affect this question about U.S.-flag vessels?

✅ Before You Answer

• Identify which choices, if any, correspond to actual, existing FCC rule Parts related to maritime radio services. • Confirm which Part of the CFR is commonly cited in study materials for GMDSS equipment requirements and radio procedures for ships. • Eliminate any option that is not a current or correct designation for U.S. regulations (for example, outdated organizations or non‑existent FCC parts).
