As a pilot, you’re probably aware that most U.S. civil aircraft are required to carry emergency beacons. In the past, planes were generally equipped with 121.5 MHz transmitters, but these have largely fallen out of use – and for good reason. In order for another aviator to pick up a distress signal from a plane in range, he would have to be listening to that particular frequency at just the right moment.

These days, satellites associated with Search and Rescue Satellite-aided Tracking are mostly responsible for picking up distress signals. Since these satellites stopped monitoring the 121.5 MHz frequency in February of this year, newer-generation emergency locator transmitters are especially critical. They operate at 406 MHz and can be picked up easily via satellite. When it’s your safety at stake, why trust old technology?
