Hi Guys,
Ive been revising for my Air nav exam which i hope to do next week, however, i can't for the life of me work out how to do this question and cant find anything on the internet:
An aircraft travels north along the same meridian from latitude 30 15’ south to 14 00’ south. What is the distance flown in kilometres?
Correct answer: D - 1806 km
i also use PPLTutor which is a great help. It tells you how to answer questions like this but i get a different answer ill post the PPLTutor page below:
E.g. An aircraft travels south along the same meridian from latitude 27°30'N to 02°15'S. What is the distance flown in kilometres?
27°30'N + 02°15'S = 29°45'
29°45' x 60 = 1785nm.....................HERE I GET 176700?????
1785nm x 1.852 = 3305.82 km
any help will be much appreciated.
Cheers
Matt.
