Improved Effectiveness Through Availability Models 640571
Aircraft availability is influenced not only by reliability and maintainability characteristics but by support assets and maintenance and operational policies as well. General Dynamics has developed models to (1) measure quantitatively the contribution of reliability and maintainability to aircraft availability, (2) measure quantitatively the support assets to achieve the inherent availability of a fixed quantity of aircraft, (3) measure airborne effectiveness as a function of reliability, operational concept and mission requirements, (4) isolate major problem areas, and (5) predict the improvements in operational capability for corrective action decisions. These models were developed for the B-58 program in 1962 and are now being used for the F-111. The Air Force has made decisions relative to the major problem areas found in the B-58 program. These decisions have resulted in a great improvement in the B-58 program as predicted by the models.
