Passengers are unlikely to be unaware of the complexity of the aircraft systems that are hidden from view. After all, their onboard interactions are limited to aircraft seats, flight attendants and in-flight entertainment systems. Like a human nervous system, an aircraft’s wiring carries signals and information critical to the safe operation of the airplane. Carlisle IT, W.L. Gore and AeroFlite are a few of the companies that design and manufacture “the nerves.” Connecting everything from the fly-by-wire flight control systems to the coffeemaker in the galley, miles of wires, thousands of connectors, and tens of thousands of support brackets have to be cut, bundled, tested and installed.
