With requirements for aircraft to meet more stringent guidelines for underwater beacon operations, L3Harris responded with its 90-Day Beacon upgrade. This solution provides a more capable, certified underwater locating beacon for all L3Harris Cockpit Voice and Flight Data Recorders. The 90-Day Beacon is a long-life battery-operated underwater acoustic pulse generator (beacon/pinger) that is activated when the water switch is immersed in either fresh or salt water. The standard for beacons, as defined in TSO-C121B, calls for beacons to operate for a minimum of 90 days, upgraded from 30-days. Factory-approved L3Harris 90-Day Beacon retrofit kits help improve the traceability and performance of your L3Harris recorders.
- Triples the guaranteed uninterrupted operation life of current beacons once activated
- Exceeds all requirements of FAA TSO-C121b and SAE 8045A
- Easily mounts to existing L3Harris voice and flight data recorders
