Abstract
Location of the wiring in the aircraft determines the combination of vibration, moisture, heat and physical installation stresses that the wire will be exposed to. Different locations will have some or all of these factors, and at varying levels, and as such, the aging rates will vary. FAR Part 25.1353, paragraph (a) defines the requirement to prevent a single point failure in electrical equipment, controls and wiring, and states: "Electrical equipment, controls, and wiring must be installed so that operation of any one unit or system will not adversely affect the simultaneous operation of any other electrical unit essential to the safe operation." Paragraph (b) deals with the wire grouping, routing and spacing, and states: "Cables must be grouped, routed, and spaced so that damage to essential circuits will be minimized if there are faults in heavy current carrying cables." So, the factors which influence wiring design of aircraft systems should be addressed properly. This paper describes about the factors that degrade the EWIS and guidelines about the wiring components which play important role in EWIS.
