Digital Flight Data Recorder Resolution Requirements

This regulation allows operators of specified airplanes to operate those airplanes under part 121, part 125, or part 135 without meeting the resolution requirements for certain parameters of information recorded by flight data recorders. Shortly before the compliance date for the regulations, the FAA received information from airplane manufacturers that certain airplane models in service did not meet the resolution requirements. This regulation is needed to allow operators of these airplanes to continue operating these airplanes with their current recording capabilities until the FAA is able to determine the appropriate remedy for this problem.
