Why is it so Difficult to Design a Flight Recorder?Download PDF
Flight Data Recorders (FDR) are avionics units that record flight data, voice, data link and other information into memory that 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).

There are organisations that wish to develop their own FDRs rather than purchase them from FDR manufacturers in order to develop the technology in-country, reduce costs and/or to be able to create highly customized recorders for particular applications (such as launcher or missile testing). However, designing an FDR to international standards of crash survivability is a very difficult task. This white paper details the requirements for an FDR, how they are built and what options third parties have for streamlining their own FDR developments.
