The increasing number and complexity of electrical/electronic systems installed in future transport aircraft will result in higher production and operating costs, unless significant advances are made in installation concepts. Boeing studies show that the fabrication of an electrical interconnection system is a significant cost factor in the manufacture of transport aircraft. Also, as the number and flight criticality of electrical/electronic systems grow, the significance of a reliable, EMI-immune and maintainable interconnect system increases. The current design concepts are neither adequate nor compatible with the installation of Fly-by-Wire/Light and Power-by-Wire Flight critical systems. Future interconnect systems must reduce the production costs associated with signaling/powering and provide a reliable, EMI-immune and maintainable system. A new interconnect system, described in this paper, combines signal and power distribution into a single cable.
