Electrical Wiring Interconnect Systems Aircraft Zones and Glenair Signature Series Interconnect Technologies COMMERCIAL AIRCRAFT
T his interconnect design and application guide is broken down into traditional aircraft zones as defined in RTCA/ DO-160. Interconnect technology for individual sections and equipment-sets within each zone is presented in enough detail to enable EWIS designers to understand the broad range of options available and make sound specifications within each area of responsibility. Leveraging the talents of EWIS engineer Bob Johnson, Glenair has developed a number of Signature interconnect technologies for commercial aircraft, which are presented in the context of each zone.
ZONE 7: EMPENNAGE AND VERTICAL STABILIZER TIP High Vibration Extreme Temperature Range -55° to +200°C De-Icing Exposure Wide Pressure Changes
1. Fuselage 2. Instrument Panel Console and Equipment Rack 3. Nacelle and Pylon
4. Engine and Gear Box 5. Wing and Wheel Well 6. Landing Gear 7. Empennage and Vertical Stabilizer Tip 8. Cabin interior volume
To assist designers in the specification of appropriate interconnect components for use in each zone, each spread in this document presents applicable “DO-160 Environmental Conditions and Test Procedures for Airborne Equipment,” and the Glenair interconnect technologies that meet or exceed these requirements. As application guidelines for key environmental stress factors including vibration, shock, ground survival temperature, pressure differential, operating temperature, and moisture can change with each zone, only those applicable specification references are noted.
CATALOG VERSUS CUSTOM / TAILORED TECHNOLOGIES This design guide primarily presents proven-performance electrical interconnect technologies that can be sourced directly from catalog offerings. This includes the Bob Johnson signature series technologies which are highlighted for each zone. Designers looking to resolve long-standing problems or improve performance in such areas as size, weight, and power frequently turn to custom / tailored solutions. In both events, selections must be aligned with Federal Aviation Administration 14 CFR 25.1701 which states that EWIS components must be of a kind and design appropriate to its intended function and perform the function for which it was intended without degrading the airworthiness of the airplane. Responsibility for these determinations resides with the aircraft manufacturer.
