Emergency Locator Transmitters (ELTs) are devices used in aviation and maritime settings to help locate aircraft or vessels in distress. When activated, they emit a distress signal on specific frequencies, allowing search and rescue teams to pinpoint the location of the emergency. ELTs are typically installed in aircraft and can be triggered manually or automatically upon impact. These devices are crucial for enhancing safety and improving response times during emergencies. They are often required by regulations for commercial flights and are also used in private aviation. The signals sent by ELTs can be detected by satellites and ground stations, facilitating efficient rescue operations.
