What is the function of an Emergency Locator Transmitter (ELT)?

An Emergency Locator Transmitter (ELT) is designed specifically to transmit a distress signal in the event of an aircraft accident or crash. When activated, the ELT emits a signal on a specific frequency that can be detected by search and rescue satellites, as well as other aircraft and ground stations. This signal helps rescuers locate the downed aircraft quickly, significantly increasing the chances of survival for any occupants.

In situations where an aircraft has gone down, the ELT serves as a critical tool for communication, ensuring that emergency responders are alerted to the aircraft’s location, which is essential for timely rescue operations. The proper functioning of an ELT is mandated by aviation regulations, making it a vital piece of safety equipment for all aircraft.
