Flight recorders have helped improve aviation safety since their introduction in the 1950s, providing vital information to ensure that, in the event of an accident, investigators can learn more about the chain of events leading up to it. Flight recorders have evolved over time to meet new regulatory mandates, to exploit new technologies, and to increase the amount of information available to accident investigators.

Regulatory bodies mandate what data should be stored, for example, the FAA stipulates the requirements for FDRs in title 14 of its code of federal regulations, known as the federal aviation regulations (FAR). It defines operating and flight rules under which aircraft operate. These include parts 91, 121, 125, 129, 133, and 135 that segment aircraft into different groups depending on their application. Subpart F of the standards in title 14 (aeronautics and space), part 23 (airworthiness standards: normal, utility, acrobatic, and commuter category airplanes), describes what equipment is required for the respective part.

Mandatory Parameters and Data Storage Requirements for Flight Data Recorders

The data required has, in general, increased over the years and this is certainly the case for optional data operators also want to store, such as additional parametric data and image data. This white paper examines what parametric data is required by regulatory bodies, how data is processed for FDRs and what features FDRs need to meet current and future needs.
