A "MAYDAY RELAY" call is transmitted by a station that is not in distress. What is the purpose of this call?
To cancel a false distress alert.
To test the GMDSS equipment at full power.
To forward a distress message received from another station that cannot transmit it itself.
To indicate a less urgent medical situation.
For a deep-draft vessel planning a passage through a constricted channel, which two publications are most critical for calculating under-keel clearance?
List of Lights and Sailing Directions
Tide Tables and the largest scale Nautical Chart
ALRS Volume 5 and the IMDG Code
Nautical Almanac and International Code of Signals
What is the primary function of the Digital Selective Calling (DSC) system within GMDSS?
To provide real-time voice communication for routine traffic.
To send and receive detailed weather maps.
To send automated, digitally encoded alerts and calls that direct stations to a specific voice channel.
To print out navigational warnings.
A vessel's Safety Management System (SMS) is a mandatory publication primarily because it:
Replaces all other international safety conventions.
Provides the ship-specific procedures to ensure safe operation and pollution prevention.
Contains the manufacturer's manuals for all equipment.
Is written and published by the IMO for each individual ship.
An urgency (PAN-PAN) message concerning a medical evacuation would most likely be broadcast to shore authorities using which GMDSS communication function?
EPIRB
