Clarification of ELT Requirements

September 4, 2008 — This week the National Oceanic and Atmospheric Association (NOAA) sent out notifications to U.S. aircraft owners regarding upcoming changes in emergency locator transmitter (ELT) services. NOAA reminds owners that after February 1, 2009, satellite coverage of 121.5 MHz ELTs will end and that only ground-based monitoring will take place. NOAA recommends that aircraft owners transition to the improved digital 406 MHz ELT systems.

This has caused some confusion among aircraft owners, many of whom feel they are now required to upgrade to the 406 MHz units. This is not the case. The FAA has not made 406 MHz ELTs mandatory. There is no requirement in the U.S. to upgrade to the 406 MHz systems. Installing a 406 MHz ELT is solely an option at the discretion of the aircraft owner.
