90-Day Beacon Upgrade

Upgrade for L3 flight data recorders.

With requirements for aircraft to meet more stringent guidelines for underwater beacon operations, L3 responded with its 90-Day Beacon upgrade, which provides a more capable certified underwater locating beacon for all L3 Cockpit Voice and Flight Data Recorders. The 90-Day Beacon is a battery-operated underwater acoustic pulse generator (beacon/pinger) that is activated when the water switch is immersed in either fresh or salt water. The new standard for beacons, as defined in TSO-C121B, calls for beacons to operate for a minimum of 90 days. Factory-approved L3 90-Day Beacon retrofit kits are available for customers today.

The L3 90-Day Beacon:

  • 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 L3 voice and flight data recorders

Creating an industry standard

L3 believes that the aviation industry is moving toward a 90-day underwater location beacon standard. With the introduction of the L3 90-Day Beacon in 2015, L3 has made a commitment to provide upgrade kits that are in accordance with the 90-day beacon mandate, allowing operators to remain in factory Component Maintenance Manual (CMM) compliance as they upgrade their fielded recorders.

Designed to perform, built to survive

The 6.7-ounce aluminum-cased L3 90-Day Beacon is watertight, and capable of operating at depths of 20,000 feet (6,096 meters) and has a direction range of 2,000 to 4,000 yards (1,800 to 3,500 meters) depending on environmental factors. It is built to withstand a sustained pressure of up to 8,700 psi.

Easy to maintain

The L3 90-Day Beacon requires a routine maintenance check every two years as outlined in the L3 Component Maintenance Manual (CMM). Its long-life battery should be replaced every six years.

Specifications

The beacon will provide a minimum of 90 days of uninterrupted operation once activated complying with TSO-C121b, which is an upgrade to the 30-day beacon. It is tested to, and meets or exceeds, all requirements of FAA TSO-C121b and SAE 8045A. The beacon’s batteries are tested in accordance with TSO-C142a.
