| Abstract | The F-22 is contractually required to be significantly more reliable than the F-15C/D. Prior to the Gulf War, the F-15 C/D's Mean Time Between Maintenance (MTBM) total was 0.6 hours. The F-22's MTBM (total) requirement is 3.0 hours. This required improvement in maintenance demand is based on improvements in equipment reliability. This high reliability must be achieved in spite of increased functional requirements, subsystem complexity and exposure to more severe induced operating environments. The F-22 Team's approach to designing reliability into subsystem hardware is called the F-22 Subsystem Integrity Program. The goals of the program are to increase reliability, campaign effectiveness and safety. These goals will be attained through a rigorous application of engineering principals including life analyses and realistic environmental testing. As part of the Subsystem Integrity Program, the F-22 Team sponsored industry wide supplier conferences to share design, analysis and test approaches and results. The purpose of this paper is to summarize the top level management and technical lessons learned in the implementation of the F-22's Subsystem Integrity Program. The two most important management lessons learned are (1) schedule-the disciplined implementation of the integrity program was key to keeping flight certification process on schedule and (2) cost-reliable subsystem components reduce initial acquisition costs (initial spares) as well as customer life cycle costs. A key technical lesson learned is that many Mil-Std tests are not adequate in severity or duration to achieve the cost and schedule benefits described. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
