When bundling open wiring in aircraft, what is a critical consideration?

When bundling open wiring in aircraft, maximizing the number of cables is crucial for several reasons. In aircraft systems, space is often limited, and efficient use of that space is necessary to optimize both weight and layout. Grouping multiple cables can reduce the overall volume of wiring by minimizing the individual runs required throughout the airframe. This approach not only saves weight but also simplifies installation and maintenance, as it can reduce the potential for interference among individual wires.

However, it is essential to ensure that the bundled wires are organized properly to maintain electromagnetic compatibility and prevent degradation of signal quality or integrity. By maximizing the number of cables in a bundle, you also enhance efficiency in the electrical distribution system, provided that proper practices for cable management and insulation integrity are followed.

Using only insulated wires or ensuring they are all the same length may have their own importance in specific contexts but are secondary to the overarching objective of space and weight management in aircraft wiring systems.
