What benefit does AC power distribution provide in large aircraft?

AC power distribution offers significant advantages in large aircraft, particularly in terms of reduced weight. This is primarily due to the ability to use smaller wiring and components compared to direct current (DC) systems. Specifically, AC systems can transmit power more efficiently over long distances without significant losses, allowing designers to select lighter gauge wires.

Additionally, AC systems can utilize transformers and other devices that are smaller and lighter than their DC counterparts, which further contributes to the overall reduction in weight. The reduction in weight is crucial for aircraft performance, as it can lead to improved fuel efficiency and increased payload capacity.

While increased current capacity, greater efficiency in heating systems, and lower maintenance requirements are benefits associated with electrical systems in aviation, these options do not specifically highlight the primary advantage of AC distribution in large aircraft as effectively as the reduction in weight through the use of smaller wiring and components.
