Ejectable flight data recorder systems, methods, and devices

This invention describes a specialized 'black box' for aircraft that can eject during an emergency. It's designed to float and survive impacts, especially in water, protecting its stored flight data. Once in the water, it deploys multiple listening devices (hydrophones) that spread out to detect the aircraft's underwater beacon, while also transmitting a distress signal to help rescuers find it.

Why it matters: Since 2017, satellite communication for remote distress signals and underwater acoustic processing for beacon detection have become significantly more robust.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSpecialized housing, ejection, acoustic sensors, power system.
