Why is it so Difficult to Design a Flight Recorder

Why is it so Difficult to Design a Flight Recorder?


Flight Data Recorders (FR) are avionics units that record some combination of a mandatory set of flight data, optional extra data, and voice, data link, and images into storage. This storage is encased in materials designed to protect against stipulated crash conditions. They are mandatory by law on some aircraft (airliners, for example) and desired on many others (both in civilian and military applications).

Some organizations may wish to develop their own FRs, rather than purchase them from FR manufacturers, to develop the technology in-country or create highly customized recorders for particular applications. However, designing an FR to international standards of crash survivability is a challenging task. This white paper details the requirements for an FR, how they are built, and what options third parties have for streamlining their FR developments.
