D You are planning a voyage between Portland, LAT 4605'N, LONG 12400'W, and Korea via LAT 4400'N, LONG 15500'E. Which statement is TRUE? (Use gnomonic tracking chart WOXZC 5270) Distance is measured in 60-mile segments using the length of a degree of latitude at the mid-latitude. The vertex of the great circle track is north of the Aleutian Islands. You can sail a great circle track between the two points. You can steam on course 270T, at latitude 52N, between longitudes 149W and 160W in a composite sailing. Great Circle Sailing
B You are on a voyage from Nome to Honolulu via Unimak Pass (LAT 5430'N, LONG 16430'W). The great circle track passes through a point at LAT 3800'N, LONG 16140'W. Using gnomonic chart WOXZC 5270, determine which answer is TRUE. (The great circle distance, Unimak Pass to Honolulu, is 2013 miles.) The northern vertex of the great circle track would lie between Unimak Pass and Nome. A great circle course would offer no significant advantage because the rhumb line course is close to 180. A great circle track results in a significant savings in distance when compared to a rhumb line. Distance of the great circle track is measured by using the length of degree of latitude at the mid-latitude of the track. Great Circle Sailing

The Aleutian Islands are not a navigational hazard on the direct great circle track. The northern hemisphere vertex is east of the arrival position. The final course angle lies in the northeast quadrant. A composite sailing with a limiting latitude of 51N will clear the Aleutian Islands. Great Circle Sailing

At your highest latitude, the sun will be visible at upper and lower transit if the voyage occurs on 21 June. Military exercises north of 53N, between 150W and 165W, will not affect your voyage. The northern hemisphere vertex lies to the west of your arrival position. You must plot a composite sailing to remain south of the Aleutians. Great Circle Sailing
D Which statement about a great circle track between Cape Flattery (LAT 4830'N, LONG 12500'W) and Guam (LAT 1400'N, LONG 14500'E) is TRUE? (Use gnomonic tracking chart WOXZC 5270) The entire track line is to the west of the Northern Hemisphere vertex. Distance is measured by determining the length of a line in minutes of arc from the midpoint of the track to the point of tangency. When plotted on a Mercator chart the great circle track will appear as an S curve with the curve reversing at the latitude of the point of tangency (30N). Military exercises being carried out within a 150 mile radius of LAT 4710'N, LONG 13730'W will interfere with the proposed track line. Great Circle Sailing

A great circle track is not significantly shorter than a rhumb line track. When plotted on a Mercator chart, the track line will be convex to San Francisco. You will cross the Northern Hemisphere vertex where the track line crosses LAT 45N. Distance is measured by using the length of a degree of longitude at the mid-latitude line. Great Circle Sailing

The entire track line is west of the Northern Hemisphere vertex. Distance is measured using the length of a degree of longitude at the point of tangency. You will cross the Northern Hemisphere vertex at the approximate longitude of 159W. A composite sailing should be used to avoid the Bonin Islands. Great Circle Sailing

(Use gnomonic tracking chart WOXZC 5270) A great circle between departure and arrival with Mercator legs north of the Aleutians A great circle between departure and arrival with parallel sailing where the track intersects the 50N parallel A great circle from departure to the mid-longitude at 50N, then another great circle to arrival A great circle to 50N, 153W, parallel sailing to 50N, 173W, then a great circle to arrival Great Circle Sailing
D You are planning a voyage from LAT 4830'N, LONG 12500'W to Korea via LAT 4830'N, LONG 15300'E. Which of the following track lines would you select for the safest and most direct route? (Use gnomonic tracking chart WOXZC 5270) Parallel sailing along 4830'N Rhumb line track between the two points Great circle track line between the two points Great circle to LAT 5100'N, LONG 17800'W, parallel sailing for 80 miles, then great circle to the via point Great Circle Sailing
