SCALER was developed in 1973-74 for the Engine Life Management Group ELMG as the Navys self-validating actuarial method of statistically projecting aircraft engine removals and rework requirements, and of periodically providing management a usable analysis of removal data. The method separates the effects due to administrative policy changes, statistical fluctuations, changes in engine age populations, and changes in engine reliability. The report describes the method, assumptions, calculations, and output reports.
