Question 1889Navigation General

70% to pass

Except for N-S courses, and E-W courses on the equator, a great circle track between two points, when compared to a rhumb line track between the same two points, will _______________.

A be nearer to the pole or the equator depending on the latitudes of the arrival and departure positions
B be nearer to the pole in the Northern Hemisphere and nearer to the equator in the Southern Hemisphere
C always be nearer to the equator
D always be nearer to the elevated pole
AI Explanation

The correct answer is D) always be nearer to the elevated pole. A great circle track is the shortest distance between two points on the Earth's surface, as it follows the curvature of the Earth. In contrast, a rhumb line track is a straight line on a Mercator projection, which distorts the shape of the Earth. Except for north-south courses and east-west courses on the equator, a great circle track will always be nearer to the elevated pole compared to a rhumb line track between the same two points. The other options are incorrect because: A) A great circle track is not necessarily nearer to the pole or the equator, it depends on the specific locations. B) The relationship between the great circle track and the rhumb line track is the same in both the Northern and Southern Hemispheres. C) A great circle track is not always nearer to the equator.
