FAA adopts rule to improve duration and durability of black boxes

摘要

The FAA has approved a regulation that requires cockpit voice recorders (CVRs) to retain the last two hours of conversation. As part of the regulation, the FAA is imposing additional requirements related to CVRs and digital flight data recorders (DFDRs). The requirements do not affect all aircraft manufacturers, air carriers, and operators, and have different timetables and applicability for new vs. existing aircraft. The requirements reflect most of the recommendations made by the National Transportation Safety Board (NTSB).
