Along a great circle (geodesic on a sphere) other than a meridian or the equator one constantly changes the bearing wrt to the meridians crossed -> orthodrome, a straight course allways ends up at a pole -> loxodrome. | |

As long as you're continuing on a straight line, or a straight arc as it were, you'll end up at the correct point. | |
