The use of sophisticated technology nowadays makes it possible to determine the location of the source of a distress signal from emergency locator transmitters. In simple terms, an ELT transmits a coded radio signal that is received by an orbiting satellite. The satellite then re-transmits the signal to a ground station and passes it on to an appropriate mission control center. This is determined in part by the national code included in the signal.

One of the most popular ELTs today is the Ameri King ELT. It is FAA TSO-C91 approved and meets FCC rules for improved satellite detection. It features voice transmitting capability, visual “on” lights (for both ELT main unit and remote panel), and uses standard batteries. The ELT further includes a low drag aircraft antenna as well as a portable antenna to enable you to bring along the ELT in case you need to leave the aircraft behind.
