With world-leading technology designed to survive helicopter accidents, the CPI-406 ELT system exceeds international ELT requirements.

The crash-survivable beacon airfoil unit (BAU) separates from the aircraft at the onset of an incident, escaping the devastating effects of the downing and emitting a distress signal linked to the aircraft. With an additional encoding option, the BAU can transmit last-known latitude and longitude in order to aid in search and rescue. It floats indefinitely, helping crew survive the crash.

The CPI-406 includes deployable cockpit voice and flight data recorders, emergency locator transmitters and aircraft monitoring systems.
