Increased use of advanced electronics has given modern combat aircraft phenomenal levels of performance, but at a price in initial cost, maintenance workload and aircraft availability. Hence, aircraft design is shifting to give equal emphasis on performance, affordability, maintainability, and reliability in the development of avionic systems. This paper discusses the challenges and benefits of an avionics architecture concept which integrates avionic functions at the system level thereby improving the systems accuracy, increasing its immunity to failure, and decreasing its reliance on multiple redundant sensors. This design philosophy, which permits resources to be shared across subsystems, requires a highly coupled system-wide management and control program operating system supported by a wide-band data distribution network, high-speed data and signal processors, and extensive mass memory. The implementation strategy for this avionics architecture is the system-wide use of common modular building blocks using advanced microelectronics such as VHSIC, standard 34 ATR modules and integrated racks, and interconnected by fiber optic networks. The generic integration approach and architecture produced by the PAVE PILLAR program is the foundation for avionics development in next generation aircraft for the U.S. Dept. of defense and include such aircraft as the USAF Advanced Tactical Fighter.
