Module 9 - GMDSS & Safety Equipment
EPIRB, SART, And Survival-Craft VHF Checks
Active recall
Section 10 of 10
Explain the main idea from epirb, sart, and survival-craft vhf checks in your own words.
A 406 MHz EPIRB sends a coded distress alert through Cospas-Sarsat; many units also provide a 121.5 MHz homing signal. Keep registration and coding correct, the float-free mounting unobstructed, the hydrostatic release and battery within date, and test only with the manufacturer's self-test procedure.
A radar SART helps rescuers locate survival craft by responding to suitable radar interrogation; an AIS-SART transmits locating reports for AIS display. Mount or deploy as instructed, keep batteries in date, and use only approved test modes. Survival-craft handheld VHF range is limited by low antenna height; protect the radio, know the channels and controls, and manage primary, spare, or emergency batteries exactly as specified.
Key points
- 406 MHz alerts satellites; 121.5 MHz supports local homing where fitted.
- Float-free EPIRB mounting must not be obstructed.
- SART type, mounting height, battery, and test method affect usefulness.
- Handheld VHF range and endurance are limited; conserve and maintain batteries.
