How do you apply a measured distance using the divider?

Let’s assume you calculate a distance of 10.5 nautical miles, and you want to apply it in your true course starting at point A, assuming your true course is 110 degrees.

Use the dividers and span a distance of 10.5 miles on the latitude scale which is closest to point A.

Apply this span on your course, placing one leg of the dividers at point A and the other leg on the course, marking the new position B.

We can see that the distance from A to B is 10.5 nautical miles.
