ABSTRACT
Flight safety is influenced by many factors including quality of aircraft and its systems, quality of ground service, pilot skills and air traffic organization. Flight Data Recorder (FDR) is an aircraft system that increases flight safety especially by allowing experience feedback from aviation accidents for improving de-signs of aircraft and operational procedures. FDRs have to meet several basic requirements to perform the expected functions e.g. the particular set of recorded parameters and the length of the record, the protection of the record against damage or destruction and the measures for early detection of the record. The ICAO recommendations and standards regarding the number and type of the recorded parameters and the length of record of FDRs are listed in Annex 6 Operation of Aircraft. The article summarizes recent changes of ICAO Standards and Recommendations on FDRs used in International Commercial Air Transport Airplanes.
