Module 9 - GMDSS & Safety Equipment
GMDSS & Safety Equipment decision map
GMDSS & Safety Equipment is not just a memory topic. In SRC revision it must lead to the correct channel, priority, phrase order, listening watch, and follow-up action.
A strong answer says what type of traffic it is, which channel or DSC function applies, what the first spoken words should be, and what the operator listens for next.
Key points
- Priority: decide whether the traffic is routine, safety, urgency, or distress.
- Channel or function: connect GMDSS sea area A1 with the correct voice or DSC path.
- Message quality: give identity, position if relevant, useful detail, and a clear request.
- After transmitting: release PTT, listen, write down instructions, and avoid blocking higher-priority traffic.
What priority is this traffic?
Strong response: Choose the safest priority before speaking.
Which channel, DSC function, or procedure applies?
Strong response: Use the right route and move off calling channels when required.
What must the other station know?
Strong response: Give identity, position when needed, and the exact request.
What happens after the call?
Strong response: Listen, acknowledge instructions, and keep a written note if the traffic matters.
