You depart LAT 16°24'S, LONG 169°38'W, for LAT 16°24'S, LONG 174°52'E. What are the course and distance by parallel sailing?

Correct Answer: Option D — 270°T, 892 miles

Parallel sailing applies when the latitude remains constant. The distance is calculated by the formula: Distance = DLo × cos(Latitude). With a DLo of 3570 minutes (169°38'W to 174°52'E) and a latitude of 16°24'S, the calculation yields 3426.6 minutes, which equates to 892 miles on a 270°T course.
