> > A minute of arc on the planet Earth is 1 nautical mile. > Only if that minute of arc lies on a great circle route. You missed out some context for that quote that already makes it clear that it's talking about a great circle: > A nautical mile is based on the circumference of the planet Earth. If you were to cut the Earth in half at the equator, you could pick up one of the halves and look at the equator as a circle. ... A minute of arc on the planet Earth is 1 nautical mile. |
