Integrated Vehicle Management Systems (Systemes de gestion de vecteur integre)

摘要

For avionic systems, performance and affordability can be achieved by functionaland physical integration. 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.
