# Longitude and latitude in aviation

I have two coordinates A = (60◦ N, 30◦ E) and B = (60◦ N, 150◦ E). I want to calculate the shortest possible route between these two points and also I want to know how far north does the route goes.

I have no idea how to calculated the how far north does the route goes so I am asking help.

• That's basic geometry? Also, it sounds like homework to me. – Erik Sep 12 '19 at 9:10
• Shortest possible route betweentwo points are called '' great circle route'' or ''orthodromic'', you should find answer by searching with these key word – J.R Sep 12 '19 at 9:19
• yes I can calculate the shortest possible route, but how can I calculate how far north does the route goes – engineerstudent Sep 12 '19 at 12:01
• For that trivial case, the maximum occurs at the midpoint. If you've calculated the route, you should have that value. – Vince Sep 12 '19 at 12:25
• @Erik : It is a (basic) spherical trigonometry question, which is orders of magnitude more complex than planar trigonometry. – Martin F Sep 29 '19 at 19:18
