Modular avionics retrofit applications

Cost-benefit data on the use of common hardware and software modules across multiple weapon systems are presented. The F-111, F-15, F-16, KC-135, and E-3 aircraft are analyzed, and subsystems which are high-maintenance items that can be replaced by common modules (hardware and software) and used in all of these aircraft types are identified. It is shown that the development and retrofit of common hardware and software modules in these aircraft types for the functions analyzed will result in a saving of 2-5 billion dollars (depending upon the number of aircraft retrofits, the starting date of the program and the actual program management concept paralleling that suggested in this study). The Air Force Logistic command maintains far more aircraft than would be produced during any new aircraft development and production system. It is suggested that program decisions should be based on the total life cycle cost of maintaining the existing aircraft. Maintenance costs can be substantially reduced by inserting new technology systems designed to be highly reliable and fault tolerant, and to require minimum maintenance, as suggested
