Description
Summary:The functions and advantages of second-generation digital avionics systems are described. These digital systems have increased integration, increased reliability and flexibility, and improved man-machine interface, and they provide increases in the mean time between removal of line-replacable units and fuel savings. Different redundant processors and software are utilized to achieve fault-tolerance performance of flight control systems. The improved landing capabilities, front-panel instruments, sidestick controllers, back-lighted liquid-crystal displays, and fly-by-wire system possible with digital avionics are examined. The applications of digital avionics to military and commercial aircraft are discussed and examples are provided.
