GPS and great circles
Just got back from a flight. Was cleared just out of Carins (Aus) direct to Maleny (just north of Brisbane). Distance 704 nm.
The direction to MLY was brg 141 according to the GPS. As I got closer and closer to MLY the brg progressively dropped to 133. The CDI was centred (+/- 1 dot)
This seems like a great circle track; Convex towards the nearer pole.
But this 8 degree change seems like a lot for such a short route. Is it?
Somewhere recently was a link to a good great circle calculator...does anyone have it?
