From FAAST –
Termination of satellite monitoring of 121.5 MHz ELTs will happen in under a month. Are you ready? On 1 February 2009, the International Cospas-Sarsat Organization (U.S. included) will terminate processing of distress signals emitted by 121.5 MHz Emergency Locator Transmitters (ELTs). Pilots flying aircraft equipped with 121.5 MHz ELTs after that date will have to depend on pilots of over flying aircraft and or ground stations monitoring 121.5 to hear and report distress alert signals, transmitted from a possible crash site.
