A new appraoch to logistics support has been introduced to the development of training devices, in general, and to flight simulators specifically. The availability guarantee is now appearing in Requests for Proposals for flight simulators. Although the Government may have a primary objective to obtain a high degreee of service from training devices, it has also imposed the full spectrum of logistics considerations upon the contractor. Logistics considerations must become an integral part of the design, if a contractor is going to meet the availability requirements. This must be a consideration of design to insure a supportable trainer. This paper reviews the status of current attempts to impose availability guarantees upon flight simulator contracts, and discusses the pros and cons of this approach from the Government and contractor positions. The paper also discusses penalties applied to non-performance, and types of contracts under which these are most applicable. It addresses the current requirements for the basic "ilities" of the classical support approach, and the advisability of continued use of them. These requirements include, but are not limited to: Reliability Programs and Demonstrations, Maintainability Programs and Demonstrations, Supply Support, Support Equipment, Technical Documentation Standards, and Training. The paper evaluates each of the classical elements of support under various support concepts where an availability guarantee is imposed by contract, and offers recommendations on the level of surveillance required for each.
