What is a distinct feature of the new generation ELTs?

The distinct feature of the new generation Emergency Locator Transmitters (ELTs) is their ability to send detailed data messages. This advancement enhances the effectiveness of search and rescue operations by providing crucial information such as the location, altitude, and flight data of the aircraft in distress. By transmitting comprehensive data, these ELTs significantly improve the chances of quick and accurate responses from rescue teams, reducing search areas and facilitating a more timely rescue.

While other advancements, such as being lighter and smaller, increased battery life, and functionality limitations based on time of day, may also apply to certain ELT models, the unique capability to send detailed data messages is what sets the new generation apart and underscores its importance in aviation safety.
