The KARAT-B combines functions of a crash recorder and an airborne automated monitoring system. It provides acquisition, conversion and recording of the data incoming from aircraft sensors and equipment, storage of the data in case of a flight accident, automated control of the airborne equipment serviceability both in flight and on the ground.

The KARAT is a co-operative project of the "Aviaavtomatika" Design Bureau, GosNIIAS, the JSC "Pribor" and THALES
