Navigation Problems USCG Question #815 (Set 24)

Using gnomonic tracking chart WOXZC 5270, determine which of the following statements about a voyage from Valdez, AK, to Hilo, HI, is TRUE.

Official USCG Answer & Rule Citation

Correct Answer: Option A — A great circle track is not significantly shorter than a rhumb line track.

Per Bowditch principles on gnomonic chart analysis, the great circle route between Valdez, Alaska, and Hilo, Hawaii, closely parallels the rhumb line due to the favorable meridional alignment, rendering the distance savings negligible and making option A the only valid cartographic statement.
