🔍 Key Concepts

• Urgency communications (PAN PAN) requirements in the GMDSS (Global Maritime Distress and Safety System) procedures • Difference between distress, urgency, and safety signals and how follow‑up communications are handled • Standard ITU/USCG guidance on required listening watch time after receiving special category calls

💭 Think About

• Think about why a mobile station needs to keep listening after an urgency signal is heard—what could happen right after the initial signal? • Which of these times is commonly associated with required listening/watching periods in other radio procedures you’ve studied? • How does the need to avoid blocking the channel influence how long you should wait and listen before transmitting or standing down?

✅ Before You Answer

• Verify what the ITU/USCG rules specifically say about follow‑up watch time after urgency (PAN PAN) signals for mobile stations • Check that the time requirement you choose is explicitly tied to urgency, not distress (MAYDAY) or routine/safety calls • Confirm that the required time is a minimum listening period and not related to silence periods or DSC (Digital Selective Calling) watchkeeping requirements
