Department of Defense specifications for technical data, spares and support documentation have been the proverbial "thorn in the side" to simulator and training device suppliers for many years. These government requirements are the most significant factor in the higher prices they pay for similar commercially available devices. As military aircrew training devices change from an all organic to a Contract Logistics Support (CLS) concept, there is a real potential for significant decreases in government training device life cycle costs. With the work force stability provided under CLS, the need for the highly sophisticated and costly logistic support is dramatically reduced. This paper will evaluate the various life cycle cost factors and assess the relative impact of reducing the current government standards (MIL-STD, MIL-SPEC) to best commercial practices in a CLS environment.
