What is a key characteristic of AC wiring compared to DC wiring in aircraft?

AC wiring can handle higher power loads at reduced weight compared to DC wiring, which is significant for aircraft systems. This characteristic is primarily due to the ability of alternating current to transmit power more efficiently over longer distances without significant loss. In aviation, where weight is a critical factor for performance and fuel efficiency, AC systems are advantageous because they allow for the use of thinner conductors and lighter insulation relative to the power they transmit.

Additionally, AC systems can easily convert to higher voltages via transformers, facilitating the distribution of power throughout the aircraft while minimizing the weight of the wiring harnesses required. The ability to manage larger loads with lighter materials effectively supports the design of modern aircraft, where space and weight optimization are essential for overall performance.
