DRS Technologies has launched its new CPI-406 Emergency Locator Transmitter (ELT) at Farnborough. A modular, deployable aircraft beacon system, the CPI-406 incorporates advanced technology in a single crash-hardened unit, exceeding current ELT requirements for automatically deployable systems.
At the onset of an incident, the Beacon Airfoil Unit (BAU) separates from the aircraft and immediately transmits a distress signal, which includes the aircraft identification number, to the International COSPAS-SARSAT network. With optional Global Positioning Indicator (GPI) encoding, the BAU also will transmit the last known latitude and longitude to aid in search and rescue. In incidents occurring over water, the BAU floats indefinitely, providing reliable location of crew and aircraft and the highest rate of ELT survivability and data recovery available today.
The CPI-406 ELT was developed by the company's DRS Flight Safety and Communications unit in Carleton Place, Ontario, Canada.
The CPI-406, a 121.5/406 MHz deployable ELT, is designed to be a direct replacement for the company's CPI-113, a 121.5/243 MHz ELT system.
The recovery rate of DRS's deployable flight recorder and ELT systems exceeds 95 percent of reported incidents. Recovered data provide detailed information of the events during an incident and are used for accident investigation, training, aircraft and avionics design and manufacture, and flight safety procedure development.
