Determine the great circle distance and initial course from LAT 35°27.0'N, LONG 140°20.5'E to LAT 47°51.0'N, LONG 122°51.0'W.

Correct Answer: Option C — 4115 miles, 045°T

Applying spherical trigonometry, specifically the law of cosines for sides and the sine rule for angles, the great circle distance between these Pacific coordinates is 4115 nautical miles. The initial course is 045°T, which is the bearing of the great circle track at the point of departure.
