Abstract : Major trends in technology, weapon system performance goals and affordability for aerospace systems are occurring simultaneously. For avionic systems this performance and affordability can be achieved by functional and physical integration. 'Functionally' integrated subsystems to achieve higher performance has been greatly aided by advances in computer technology. The desire to minimize costs for these systems has been accomplished through a 'physical' integration concept based upon common modules tied through a high speed backplane. The concept, called integrated avionics, has been used on new aircraft such as the US Air Force F-22 fighter and the Boeing 777 commercial transport. Vehicle management systems provide the management of crucial flight functions and systems for advanced aerospace vehicles. These systems must have high integrity, safety, and overall fault tolerance. Low cost modular avionics are unproven for such fault tolerant systems. This becomes a key issue for investigation. This report deals with the key problems in fault tolerance for modular computer based systems. New techniques, only recently applied, provide exciting possibilities to reduce avionics costs and maintain high integrity and safety. These techniques and more are discussed in this report sponsored by the Mission Systems Panel of the AGARD.
