The Emergency Beacons are electronic devices that allow us to launch a warning to alert the rescue services of a situation with serious risk to life. There are two types:
The PLB Beacon (Personal Locator Beacon) are portable devices that do not require any installation and are designed to travel with the person, like a mobile phone. Activation of PLB Beacon is hand pressing a button.
The ELT Beacons (Emergency Locator Transmiter) are devices designed to be permanently installed in the aircraft. The activation of the ELT beacon can be manual by pressing a button or automatically in case of collision (activated by exceeding a threshold of 'G' or if it comes into contact with water).
In addition, some beacons allow tracking of our route in the Internet to people that we authorize.
