Navigation Problems USCG Question #1708 (Set 51)

You are planning a voyage by great circle from LAT 59°00'N, LONG 07°00'W via LAT 38°00'N, LONG 61°30'W. Which of the following statements is TRUE? (Use gnomonic tracking chart WOXZC 5274)

Official USCG Answer & Rule Citation

Correct Answer: Option A — All courses are in the southwest quadrant of the compass.

Great circle tracks plotted on a Mercator chart appear as curves concave toward the equator. Because both points are in the Northern Hemisphere and the track moves from the eastern Atlantic toward North America, the course remains in the southwest quadrant throughout the transit.
