🔍 Key Concepts

• Distress traffic procedures under the Global Maritime Distress and Safety System (GMDSS) and traditional radiotelephone rules • The priority of distress (SOS/MAYDAY) over all other communications • The requirement to avoid interference on the distress frequency once distress traffic is heard

💭 Think About

• When you first hear an SOS, what is the most important thing: adding more transmissions to the channel, or ensuring the distress traffic can be clearly heard and handled by the appropriate units? • Would repeating the SOS or calling the ship directly increase or decrease congestion and potential interference on the distress frequency? • Think about the standard order of priorities: distress, urgency, safety, routine. How should routine or non-essential transmissions be handled when distress traffic is in progress?

✅ Before You Answer

• Verify what standard radio procedures say about silencing other traffic when distress signals are heard • Check whether individual stations should immediately transmit, or first ensure they are not interfering with ongoing distress communications • Confirm which action best supports the clarity and priority of distress communications on the frequency
