An Emergency Locator Transmitter (ELT) is a crucial piece of safety equipment in aviation operations, which allows for the location of aircraft in distress. The main use of an ELT is to transmit a signal that can be detected by search and rescue teams, facilitating the prompt location and assistance of an aircraft in emergency situations. This technology is designed to automatically activate upon impact, although it can also be manually triggered by the pilot or crew from the cockpit to ensure a response. Understanding the operation, types, and importance of ELTs can provide insight into how these devices enhance aviation safety, so read on as we briefly discuss them.
