Q

How is "radio silence" imposed?

🔍 Key Concepts

• GMDSS distress and safety communications procedures • Who has overall control in a Search and Rescue (SAR) operation • The roles of RCC (Rescue Coordination Center), OSC (On-Scene Coordinator), and radio stations during distress traffic

💭 Think About

• In a real distress situation, who is formally given the authority to coordinate and control all communications on the distress frequency? • Is radio silence a local decision by whoever answers first, or is it part of an organized SAR command structure? • Which of the listed options represents an entity that has recognized overall SAR coordination responsibility rather than just providing communication service?

✅ Before You Answer

• Verify in GMDSS procedures who may impose silence on a distress frequency (MAYDAY SILENCE/MAYDAY SEELONCE). • Check which organization or role is formally designated to coordinate SAR operations, not just relay or handle routine traffic. • Confirm whether a coast station or LES merely supports communications, or has the explicit authority to order radio silence in distress traffic.
