Which application is an example of twisted pair aircraft wire usage?

Twisted pair wiring is commonly used in applications where minimizing electromagnetic interference (EMI) and ensuring signal integrity are critical. This type of wiring involves two conductors twisted together, which helps cancel out any potential noise or interference that may be induced from external sources.

In the context of aircraft systems, lighting circuits, including those for the standby magnetic compass, often require reliable operation with minimal signal disruption. The compass lighting must remain consistent and free from interference, especially since a malfunction in graphical displays can lead to serious operational issues.

Using twisted pair wire in this application ensures that any electrical noise from nearby systems does not adversely affect the illumination or functionality of the compass, which is crucial for navigation. This makes it an appropriate choice for such lighting circuits in aviation settings.
