Question 1900Navigation General70% to pass
The upper vertex of a great circle track is in LONG 156°00'E. Sailing eastward, the great circle track will cross the equator in LONG _______________.
AI Explanation
The correct answer is D) 114°00'W.
When sailing eastward on a great circle track, the track will cross the equator at a longitude that is 180 degrees from the longitude of the upper vertex of the great circle. Since the upper vertex is at 156°00'E, the track will cross the equator at 180 degrees opposite, which is 114°00'W.
The other options are incorrect because:
A) 66°00'W is not the correct longitude, as it is not 180 degrees opposite the upper vertex.
B) 110°00'W is not the correct longitude, as it is not 180 degrees opposite the upper vertex.
C) 66°00'E is not the correct longitude, as it is not 180 degrees opposite the upper vertex.
