Another consideration is this: Does your navigation system (FMS, GPS etc.) find great circle or rhumbline between waypoints? I've taught the system at one airline and not found the certain answer for that one.

Let's say you're at 50N 00W and you tell the black box to fly you to 50N 179W. "Great circle" would head almost over the pole and would cover 4817.4 nm; the rhumb line would head west along the 50th parallel and would cover 6968.3 nm. Surely the black box knows to fly north and not west?

True, that could be due to the change in the magnetic deviation-- I'll see if I can find a counterexample.
|Quoting Mozart (Reply 11):|
Now, what interests me is what happens between those two points: the airline will of course try to fly as close as possible to Great Circle,
