A flight data recording system includes a digital flight data recorder (DFDR) and a digital flight data acquisition unit (DFDAU) having a signal processor and nonvolatile memory for storing signals representative of a deterministic flight mode algorithm which defines a generic aircraft flight profile by preselected modes, each mode defining a flight profile operating station, the deterministic flight mode algorithm defining the nominal values of some number of sensed flight data parameters in terms of the sensed values of some number of the remaining other sensed flight parameters. At each such station, the signal processor comparing the actual sensed mandatory flight parameter value with the corresponding determined value to establish sensor accuracy.
