NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: AMEND 14 CFR 121.343 TO ALLOW USE OF DIGITAL FLIGHT DATA RECORDERS (DFDR) WHICH EMPLOY SOME FORM OF DATA COMPRESSION IF THE MANUFACTURER CAN DEMONSTRATE DURING AIRCRAFT CERTIFICATION THAT UPON RECORDER READOUT THE REQUIRED PARAMETERS CAN BE RECONSTRUCTED TO THE ACCURACY AND RANGES SPECIFIED IN PART 121, APPENDIX B, AND THAT THE RECORDED DATA ARE ADEQUATE FOR ACCIDENT INVESTIGATION PURPOSES.
In plain language (FlightFinder summary)
The NTSB asks the FAA to amend 14 CFR 121.343 to permit digital flight data recorders that use data compression, provided the manufacturer demonstrates during aircraft certification that the required parameters can be reconstructed to the accuracy and ranges specified in Part 121, Appendix B, and that the recorded data are adequate for accident investigation.
