A computer-based onboard aircraft flight information system which automatically and continuously evaluates flight data parameters determined on board, and displays information to the pilot determined from the evaluation, said flight information system comprising a computer which runs parallel to a flight control computer of the aircraft, wherein:

  • the computer which runs in parallel uses fuzzy logic to carry out risk evaluations with respect to actual aircraft flight conditions using knowledge bases implemented in the flight information system;

    the results of the risk evaluations are displayed in the cockpit;

    the flight information system determines individual risks relevant to the flight conditions and determines an overall risk therefrom; and

    the overall risk is continuously indicated on the display as a luminous bar.
