Determine the great circle distance and initial course from LAT 26°00.0'S, LONG 56°00.0'W to LAT 34°00.0'S, LONG 18°15.0'E.

Correct Answer: Option C — 3805 miles, 117°T

Great circle calculations between these points in the Southern Hemisphere require the spherical law of cosines for distance and the sine rule for the initial course. The resulting distance is 3805 nautical miles, and the initial course is 117°T, representing the shortest path across the South Atlantic.
