- Nota adicional1
- Upon contact with moisture this device will activate and send out a sonar signal for approximately 30 days. This ULB must be maintained every 2-6 years (depending on the model), with the replacement of a battery in order to be effective. This device is not meant to operate after impact on land, only when submerged in water. Special equipment and often collaboration with maritime organizations is needed in order to pick up a locator signal and further recover the units depending on the circumstances. Several investigative laboratories have previous experience in this procedure that States may draw upon for assistance.
- Contexto
- If the aircraft wreckage is located underwater and the location of the recorders is not apparent, special equipment may be necessary to identify and retrieve the devices. The FDR and CVR are equipped with an underwater locator beacon (ULB) commonly referred to as a “pinger”.
