- A ( 56° 12`N, 112° 20` E) and B (40° 43`N, 080° 50`E).
- A ( 30° 30`S, 060° 50` W) and B (48° 50`N, 080° 30`E).
- A ( 25° 25`S, 045° 30` W) and B (18° 52`S, 028° 42`E).
- A ( 63° 47`S, 120° 39` E) and B (80° 26`S, 090° 40`W).
- Find the coordinates of arrival position:
· A (45° 17` N, 113° 27` W), d.lat. = 25° 13` N, d.long. = 014° 33`E.
· A (35° 25` N, 179° 24` E), d.lat. = 29° 05` N, d.long. = 024° 18`E.
· A (15° 23` N, 045° 35` W), d.lat. = 45° 27` S, d.long. = 073° 27`W.
