Abstract : This paper describes the parametric approach being pursued for the development of the test spectrum for the CF-18 center fuselage. The paper provides an overview of the F/A-18 International Follow-on Structural Test Program (IFOSTP) with emphasis on spectrum development. The specific technical elements of the spectrum development task are introduced and detailed information is provided on the CF-18 usage monitoring system, the approach to usage processing and the manoeuvre identification methodology which is forming the basis of the parametric approach to CF-18 spectrum development. A specific example of the manoeuvre identification process is provided and recommendations for future monitoring systems are offered.
