Abstract: According to one embodiment, a system for assessing health of an aircraft includes a receiver, a flight spectrum analyzer, and a health assessment analyzer. The receiver receives, from an aircraft, a plurality of measurements associated with two or more flight parameters. The plurality of measurements includes measurements spanning at least one period of time. The flight spectrum analyzer determines, based on a comparison of the plurality of measurements to a plurality of flight spectrum definitions, an amount of time the aircraft spent in each flight spectrum of a plurality of flight spectrums during the at least one period of time. The health assessment analyzer assesses a change in health of the aircraft over the at least one period of time based on the determination of the amount of time the aircraft spent in each flight spectrum and a plurality of spectrum health profiles.
