The nature of usage-related loadings, e.g. resulting from flight maneuvers, doesn't allow a description by means of power spectral density. Hence, a method comprising comparable advantages is presented that is based upon Poisson distributions for both, interarrival times and durations of usagerelated segments. Finally, it is demonstrated how such loadings can be reconstituted in real time and in a statistically correct manner.
