3 Description of available data
This section provides an overview of available data that is of possible interest for cloud computing.
3.1 Digital flight data recorder (DFDR)
DFDR, or mandatory FDR, or accident recorder, records a large number of aircraft parameters in a highly robust
unit. The primary use case for DFDRs is the investigation of aircraft loss or accidents.
Aircraft parameters that are recorded to DFDRs are a combination of the parameters that are identified by
the appropriate regulatory authority (the Federal Aviation Administration (FAA), the European Aviation Safety
Agency (EASA), the Civil Aviation Safety Authority (CASA), etc.) as being mandatory parameters to record on
DFDR, plus a series of other parameters as selected by the aircraft OEM. The quantity of aircraft parameters
that are recorded is variable and is typically related to the size and age of the aircraft (see EUROCAE ED-112A
and FAR 121.344 for current regulations; also see Appendix A).
As an example, a Boeing 737NG will record approximately 1000 different parameters, amongst which are
navigational position data, control surface position, engine parameter data, environmental control system
