When converting from magnetic course to true course, a pilot should?

When converting from magnetic course to true course, the process involves adjusting for magnetic variation, which is the difference between magnetic north and true north. In this context, variation can either be easterly or westerly, depending on the geographic location.

When the variation is easterly, it means that magnetic north is to the east of true north. Therefore, to convert from magnetic to true, the pilot needs to add the easterly variation to the magnetic course. This adjustment is crucial to ensure accurate navigation, as using magnetic headings without accounting for variation can lead to significant errors in course plotting.

The option indicating that a pilot should add easterly variation regardless of heading correctly identifies this essential practice. By adding easterly variation, a pilot ensures that the true course corresponds properly to geographical landmarks and navigational aids, resulting in a more accurate flight path.
