What is one of the main benefits of using a two-wire electrical system?

The main benefit of using a two-wire electrical system is its reduced weight. In aircraft systems, minimizing weight is crucial for overall performance, fuel efficiency, and payload capacity. A two-wire system simplifies the electrical design by requiring fewer conductors and components compared to more complex wiring configurations. This reduction not only helps decrease the overall weight of the electrical system but also aids in simplifying installation and maintenance processes. Consequently, a lighter system is advantageous in aviation, where every bit of weight savings translates into improved operational efficiency and performance.
