LSA Equipment Flashcards
How does an EPIRB work?
EPIRB when activated or in contact with saltwater will send a signal (406 mHz) containing position & HEX ID (Vessel information) to Cospas-Sarsat polar orbiting satellite system. The satellite will then send that information to the LES (Land Earth Station) which the EPIRB is registered to. The MRCC in question will then contact appropriate authorities/MRCC in the area affected. The SAR party can then home in on 121.5MHz to locate the casualty.
Where can you use an EPIRB?
Everywhere, global coverage
What is the service interval, inspection interval and battery life for an EPIRB?
5 years service life. Monthly inspection. 48h battery life in transmission mode
What is HEX ID?
Unique ID for each EPIRB containing vessel specifics and DPA.
What do you do if you accidentally activate an EPIRB?
Switch it off & call the MRCC
What does EPIRB stand for?
Emergency position indicating radio beacon
What does SART stand for?
Search- and rescue transponder
Where should you place a SART?
As high as possible, works with ground waves
How does a SART work?
Responds with a signal when interrogated by a 9gHz X-BAND Radar beam
What is the service interval, inspection interval and battery life for a SART?
5 years service life, monthly inspection, 96h battery life in Rx (stand-by mode) 8h in Tx (Transmission mode)
What does an AIS SARTs MMSI start with?
970
What is the SARTs range?
Approximately 5nm for a scanner 15m height, approximately 40nm by helicopter
How do you know a SART is transmitting?
Flashing LED and audio alert
