35、 charge of the original design or to give the design agreement for which Certification will be required from the Regulatory Authorities 3.2 Regulatory Authority in this document, this term covers the Organisations in charge to write rules to satisfy, to survey the design and to grant Navigability Ce
36、rtificate, like EASA and FAA 4 Limitations It is recognized that the installation practices contained in this standard do not necessarily represent the full requirements for a safe and satisfactory electrical and optical interconnection system. In the event of a conflict between the text of this doc
37、ument and the references cited herein, the text of this document takes precedence. However, nothing written in this standard shall override the specific requirements of a Design Authority, the Airworthiness Requirements, applicable laws or any regulation from the regulatory authorities, unless a spe
38、cific exemption has been obtained. 5 General requirements 5.1 Applicable Rulemaking The main rulemakings to satisfy for the definition of the various possible electrical installations on large aircrafts are coming from: Design technical requirements From the EASA European Aviation Safety Agency (CS
39、25) and the FAR Federal Aviation Regulation (14CFR Part 25). Organisation requirements From the EASA European Aviation Safety Agency (IR 21) and the FAR Federal Aviation Regulation (14CFR Part 21). 4) Published by: American Society For Testing and Materials (ASTM), http:/www.astm.org/.

41、 by the EASA in autumn 2008. This was also the opportunity for the authorities to group all the electrical requirements: the rules 25.17xx. b) CS or FAR 23, 27 and 29 which concern small aircraft, small and large helicopters were not updated in-line. 5.2 EWIS Definition The definition of the aircraf
42、t electrical interconnection network, now called Electrical Wiring Interconnection System (EWIS) is now given in the regulation. The retained text, coming from the EASA, is the following: CS 25.1701 Electrical Wiring Interconnection System Definition (a) Electrical wiring interconnection system (EWI
43、S) means any wire, wiring device, or combination of these, including termination devices, installed in any area of the airplane for the purpose of transmitting electrical energy between two or more intended termination points. Except as provided for in Subclause (c) of this Subclause, this includes:
44、 1) Wires and cables. 2) Bus bars. 3) The termination point on electrical devices, including those on relays, interrupters, switches, contactors, terminal blocks and circuit breakers, and other circuit protection devices. 4) Connectors, including feed-through connectors. 5) Connector accessories. 6)
45、 Electrical grounding and bonding devices and their associated connections. 7) Electrical splices. 8) Materials used to provide additional protection for wires, including wire insulation, wire sleeving, and conduits that have electrical termination for the purpose of bonding. 9) Shields or braids. 1
46、0) Clamps and other devices used to route and support the wire bundle. 11) Cable tie devices. 12) Labels or other means of identification. 13) Pressure seals. (b) The definition in Subclause (a) of this Subclause covers EWIS components inside shelves, panels, racks, junction boxes, distribution pane
47、ls, and back-planes of equipment racks, including, but not limited to, circuit board back-planes, wire integration units and external wiring of equipment. (c) Except for the equipment indicated in Subclause (b) of this Subclause, EWIS components inside the following equipment, and the external conne
48、ctors that are part of that equipment, are excluded from the definition in Subclause (a) of this Subclause: 1) Electrical equipment or avionics that is qualified to environmental conditions and testing procedures when those conditions and procedures are: i) Appropriate for the intended function and
49、operating environment, and ii) Acceptable to the Agency. 2) Portable electrical devices that are not part of the type design of the aeroplane. This includes personal entertainment devices and laptop computers. 3) Fibre optics.
