Air Navigation question bank
5 sample questions from Oxford, with the correct answer shown.
Tap an option and the page marks it. The right answer is shown either way.
Question 1
The convergency of the meridians through M and N both in the Southern hemisphere is 12°. The rhumb line track from M to N is (249°T). What is the GREAT CIRCLE track from M to N? Hint: In the Southern hemisphere, the great circle curves toward the equator, so it is GREATER than the rhumb line for a westerly track.
Question 2
The convergency of the meridians through M and N both in the Southern hemisphere is 12°. The rhumb line track from M to N is (249°T). What is the GREAT CIRCLE track from N to M? The reciprocal/return journey
Question 3
Position A is at 30°00'S 165°00'E. The great circle bearing of position B also at latitude 30°00'S from A is (100°T). What is the great circle track from B back to A?
Question 4
Position A is at 30°00'S 165°00'E. The great circle bearing from A to position B also at 30°00'S is (100°T). The great circle track from B to A is (260°T). What is the longitude of position B?
Question 5
Position D is at 30°00'N 179°00'W. The rhumb line from D to C is (090°T) due East. The initial great circle track from C to D is (287°T). What is the great circle track from D to C?
Every question comes with a worked solution, and many come with an animation that flies the problem.
