- Q127 - Navigation Problems: Oceans
311. Determine the great circle distance and initial course from LAT 08°36.0'N, LONG 126°17.0'E to LAT 02°12.0'S, LONG 81°53.0'W.
The great-circle distance between the two positions is 9076 nautical miles, and the initial course is 079 true, as determined by applying spherical trigonometry to calculate the central angle and then using that angle to compute the initial course.
