The recent initiatives by the U.S. Air Force to implement total contractor Aircrew Training Systems, (ATS) have invoked various levels of accountability with respect to development and performance. The ATS contractor(s) are faced with new, completely interrelated design verification procedures, quality assurance requirements, and implementation/interface controls. Test and Evaluation concepts established by DOD policy are directly applicable to this new environment. However, the processes are complex, requiring rigorous basic disciplines from development through the full life cycle of the system, Recognition of the T&E requirements as design objectives will significantly reduce the risks and improve utility, supportability, and the contractors profitability. This paper provides an approach to the philosophical and functional management issues associated with the measurement, evaluation and qualification of the various elements of an Aircrew Training System during both the development and the operational program phases. Included are considerations for system testability to certify the ISD, Media, Curriculum, and the trainee. The paper also addresses the Test and Evaluation contributions to performance management, product improvements, and cost benefits throughout the life of the contract.
