Digital Flight Data Recorder (DFDR) Subcommittee

Last Update: September 23, 2008

Chairman: Robert Swanson - FedEx

---

Goal: The goal of the DFDR Subcommittee is to ensure that aircraft flight data recording system standards meet airline operational needs and evolving regulatory requirements. In accomplishing this goal, the subcommittee considers issues such as including health monitoring of aircraft systems and components, flight operations quality assurance (FOQA) initiatives, and current and impending regulatory requirements.

Project: : Preparation of Specification 657: Airborne Recorder File Format

Scope: The scope of the project is to develop a standard data output file format for Enhanced Airborne Flight Recorders (EAFR). A standardized data format would allow instant import of the data file, which would be consistent with having a standardized documentation file format, as described by Specification 647A (FRED files).

Benefit: A standardized data format would allow instant import of the data file and provide consistency with the use of standardized documentation file format, as described by Specification 647A (FRED files). A standardized data format will reduce the amount of readout equipment required for FDR data transcription.
