It looks like flight aware is using Mercator... which is what I assume most navigational charts use. If it is Mercator, then straight lines on the map are lines of constant bearing in reality, so pretty straight forward to follow.


Actually, most aeronautical charts use the Lambert Conformal Conic Projection.

I'd guess that the reason it looks straight on flight aware is just that the distances are relatively small.

Why are we changing maps? I'm wondering where France really is.
