1. An evaluation system for generating fatigue spectra representing a predicted amount of stress that an aircraft will be subjected to for each of a plurality of events that are expected to occur during the life of the aircraft, the evaluation system comprising:

  • a host computer having a digitally readable medium, wherein digital data representing the expected events and aircraft load and unit condition parameters corresponding thereto reside on said digitally readable medium;

    a generator operating on said computer and having access to said digital data for generating fatigue spectra of the aircraft representing a profile of predicted stresses to which the aircraft will be subjected due to the plurality of events expected to occur during the life of the aircraft; and

    wherein said generator is preprogrammed to calculate a total stress for each of the events based on said load and unit condition parameters associated therewith by factoring said unit condition parameters to derive individual stresses and summing all the individual stresses.
