The FAA NPRM simply proposed that the flight data monitoring system “would be required to capture data according to a broadly defined set of parameters including information pertaining to the aircraft’s state (such as heading, altitude, and attitude), condition (such as rotors, transmission, engine parameters, and flight controls), and system performance (such as full authority digital engine control, and electronic flight instrumentation system).”
In the final ruling, the FAA does not specify parameters of data or specifically identify a set of performance standards that must be met. It only requires that a flight data monitoring system capable of recording
flight performance data be installed. Furthermore, the rule does not establish standards for crashworthiness or environmental testing. Compliance with 135.607 would be met by an
FDR-like system installed and recording on the helicopter.
