It is crucial that 406 MHz distress Emergency Locator Transmitters (ELT) be registered in recognized Emergency Locator Transmitter registration databases which will be accessible to search and rescue authorities at all times. The information contained in these databases concerning the Emergency Locator Transmitter, its owner, and the aircraft on which the Emergency Locator Transmitter is mounted, is vital for the effective use of Search and Rescue resources. Consequently, the proper registration of a Emergency Locator Transmitter could make the difference between success and failure of a search and rescue mission.
The final step in coding 406 MHz Emergency Locator Transmitters is registering the Emergency Locator Transmitter with the appropriate national authorities.
In accordance with IMO and ICAO requirements national authorities should provide help for making this data available to Search and Rescue (SAR) services on a 24-hr basis. The extremely important step of registering your Emergency Locator Transmitter is required to enable the proper SAR response if the Emergency Locator Transmitter is activated.
