    Description of modification

    Heli-One offers CVFDR installation for helicopters. The CVFDR system consists of a cockpit voice recorder (CVR) part and a flight data recorder (FDR) part. The CVR part records audio from cockpit area microphone and from the pilot’s and co-pilot’s headset and cabin ICS headset. The FDR part records flight parameters; i.e. what the pilot sees (indications) and what the pilot does (flight controls and other selections). The design may be adapted to other aircraft types upon request.
