Question 1888Navigation General

The correct answer is D) easterly courses in high latitudes. A great circle track provides the maximum saving in distance on easterly courses in high latitudes. This is because a great circle is the shortest distance between two points on the surface of the Earth, and it is the most efficient route for easterly courses in high latitudes, where the Earth's curvature is more pronounced. The other options are incorrect because they do not represent the optimal conditions for a great circle track to provide the maximum saving in distance. Southerly courses in high latitudes, westerly courses in low latitudes, and easterly courses in low latitudes that cross the equator do not benefit as much from the efficiency of a great circle track.
