A review of the various types of loading acting on the aircraft structure and the ability to accurately predict their magnitude and frequency of occurrence for a given aircraft usage is presented. Attention is paid to the variation in load experience and its causes, with specific reference to the variation in aircraft usage. For transport type aircraft these variations are largely defined by the variation in flight length and payload. For combat type aircraft, the variability is considerably larger and consequently more difficult. For the assessment of actual service load spectra, operational flight load measurements and/or service usage monitoring are required. The rapid development of electronics during the last decades has opened the possibility for advanced processor based service fatigue load monitoring systems at relatively low price. For transport aircraft simple usage monitoring may already provide highly relevant information. For combat type aircraft, the determination of average mission type spectra from in flight multiparameter recordings, in combination with mission usage monitoring for individual airplane tracking appears to be an adequate solution.
