The aerospace industry has long been perceived as slow to adapt to new wire harness engineering technologies and processes. Many enterprises rely on systems created in-house, with each tool being structured to support a very specific design/build process. Until recently, electrical system and wire harness development tools have not been viewed as an adequate solution for developing complex electrical wiring systems. Now aircraft systems and wiring designs are making a transition from traditional mechanical and pneumatic systems to electrical, and the entire electrical architecture of the vehicle is becoming more complex. Companies are finding that their existing solutions do not provide the needed engineering capability. But powerful new technologies are emerging and many companies are taking another look. Entrenched beliefs are changing.
