How much shorter is the great circle route?
Curve it north (or south in the Southern Hemisphere) along a Great Circle and you will find that the length of the string required to connect the two points is shorter. As an example, in a course plotted between Portugal and Florida, you can save 138 miles by taking a northerly curved route.
Is rhumb line a great circle?
On a north–south passage the rhumb line course coincides with a great circle, as it does on an east–west passage along the equator. The pole-to-pole length of a loxodrome (assuming a perfect sphere) is the length of the meridian divided by the cosine of the bearing away from true north.
What is the distance between two great circles?
The length of the shorter arc is the great-circle distance between the points. A great circle endowed with such a distance is called a Riemannian circle in Riemannian geometry . Between two points that are directly opposite each other, called antipodal points, there are infinitely many great circles,…
When do you use a great circle route?
Simply, when plotting a course over a distance of 500 miles or more it usually makes sense to travel a ‘ Great Circle ’ route between origin and destination as it will be a shorter distance over the surface of the planet than the straight route – also known as the Rhumb Line.

How many miles can you save by curving a great circle?
Curve it north (or south in the Southern Hemisphere) along a Great Circle and you will find that the length of the string required to connect the two points is shorter. As an example, in a course plotted between Portugal and Florida, you can save 138 miles by taking a northerly curved route.
