BSPI-4-2 Series 2

The BSPI-4-2 Series 2 is a flight data acquisition and processing unit designed for collection, conversion, and processing of signals from onboard aircraft systems and sensors as part of a flight data recording system.

Within the onboard recording architecture, the unit performs reception and conversion of analog signals and discrete commands, forming structured flight parameter data for subsequent recording in protected onboard storage devices.

The unit is applied on aircraft and helicopters equipped with the BUR-1-2 Series 2 onboard flight data recorder and is installed as a core element of the flight data recording system.

The product is also known under alternative designations BSPI-4-2 Series 2, БСПИ-4-2 серия 2, which refer to the same product type.
