Turbine Helicopter, Piston Helicopter. In a 2007 report from the ADS-B Aviation Rulemaking Committee, which AOPA participated in, it was determined that because ADS-B transmits a signal directly from the aircraft, it could provide safety benefits in terms of an additional tool for search and rescue. The 406 MHz ELTs also transmits a stronger signal when activated than the older 121.5 MHz ELTs, The Federal Communications Commission (FCC) requires 406 MHz ELTs be registered with the National Oceanic and Atmospheric Administration (NOAA) as outlined in the ELTs documentation. When activated, an emergency locator transmitter (ELT) transmits on A-118.0 and 118.8 MHz. Like so many other aspects of aviation technology, the basic concept of ELTs is a fallout from the military. Further deciphering of a signal takes place at the LUTs, and appropriate search and rescue operations are notified through mission control centers (MCCs) set up for this purpose. Small Jet, Turboprop. Emergency location transmitters are an essential component of the international satellite system for search and rescue. ELTs operating on 121.5 MHz and 243.0 MHz are analog devices. What this means for pilots is that those aircraft with only 121.5 MHz or 243.0 MHz ELTs onboard will have to depend upon either a nearby air traffic control facility receiving the alert signal or an overflying aircraft monitoring 121.5 MHz or 243.0 MHz detecting the alert and advising ATC, In the event that a properly registered 406 MHz ELT activates, the, Each analog ELT emits a distinctive downward swept audio tone on 121.5 MHz and 243.0 MHz, If "armed" and when subject to crash- generated forces, ELTs are designed to automatically activate and continuously emit their respective signals, analog or digital.
