| You are on a voyage from Nome to Honolulu via Unimak Pass (LAT 54°30'N, LONG 164°30'W). The great circle track passes through a point at LAT 38°00'N, LONG 161°40'W. Using gnomonic chart WOXZC 5270, determine which answer is TRUE. (The great circle distance, Unimak Pass to Honolulu, is 2013 miles.) |
| A) A great circle track results in a significant savings in distance when compared to a rhumb line. |
| B) A great circle course would offer no significant advantage because the rhumb line course is close to 180°. |
| C) Distance of the great circle track is measured by using the length of degree of latitude at the mid-latitude of the track. |
| D) The northern vertex of the great circle track would lie between Unimak Pass and Nome. |
