What is an Emergency Location Transmitter (ELT)?
Emergency Locator Transmitters (ELTs) are emergency transmitters carried on aircraft to assist search and rescue operations in remote areas in the event of an emergency such as an aircraft crash. ELTs increase the survival chances of people in distress by helping to rapidly locate the aircraft wreckage and those on board. Additionally, they reduce the danger faced by search and rescue pilots who typically operate in harsh weather conditions and rugged terrain.
Aviation regulations require ELTs to be installed and ready for use on aircraft. ELTs transmit radio signals to satellites to determine location. You can find more detailed information about how ELTs work in this article.
Purposes of ELT Usage
Emergency Locator Transmitters (ELTs) have been proven necessary in reducing the response time of search and rescue operations, which can be very critical in remote locations where access is difficult. Thanks to the rapid identification of the aircraft crash location and those affected, search and rescue teams can provide emergency medical assistance and facilitate the transfer of victims to a medical facility, significantly increasing their survival probability.
Additionally, these emergency transmitters have the added benefit of reducing the danger faced by search and rescue pilots. Thanks to ELTs, search and rescue teams can go directly to the crash site without having to conduct a time-consuming search. This saves valuable time and resources, especially in severe weather conditions and challenging terrain.
The use of ELTs has significantly increased the effectiveness and safety of search and rescue operations. According to the latest issue (No:48) of the Cospas-Sarsat system data document, between September 1982 and December 2021, the Cospas-Sarsat System assisted in the rescue of at least 57,413 people in 17,663 search and rescue events. In aviation emergencies between January-December 2021, a total of 379 people were rescued in 206 search and rescue events.

The use of ELTs is part of aviation regulations in most countries. The International Civil Aviation Organization (ICAO) mandates the use of ELTs on most aircraft with specific requirements depending on the type of aircraft and operating conditions. Failure to comply with these regulations can result in significant fines and other penalties. Additionally, most countries have their own regulations governing the use, installation, maintenance, and testing of ELTs, which may include additional requirements and standards.
Finally, ELTs provide an additional layer of safety for passengers and crew. In any accident or emergency, knowing that emergency teams will be notified provides confidence and comfort to those on the aircraft. Additionally, since authorities will immediately have information about the aircraft's location, the presence of ELTs on an aircraft can serve as a deterrent to potential hijackers or terrorists.
