🔍 Key Concepts

• Digital Selective Calling (DSC) Distress alert procedures in the GMDSS system • The purpose of automatic repetition of a distress alert if no acknowledgement is received • The typical time delay window used so you don’t flood the system but also don’t wait too long in an emergency

💭 Think About

• Think about how urgent a DSC distress alert is: would the system wait a long time or a short time before repeating if there is no response? • Compare each time range with what would be reasonable to allow a coast station or ship time to see and acknowledge the alert. • Which option best balances speed in an emergency with avoiding excessive repeated alerts on the distress frequencies?

✅ Before You Answer

• Recall or look up the GMDSS DSC distress procedures in your study manual or ITU/USCG materials, especially the section on automatic alert repetition. • Verify whether the delay is measured in minutes, not seconds, and check if the official guidance gives a range of minutes similar to one of the choices. • Confirm that the timing is for a shipboard DSC distress call not yet acknowledged, not for routine or safety calls.
