Did a little more "research"... (blindly shooting some search requests at google) Something that came up was, the "Lambert Conformal Conic" Projection. I also had the chance to ask a real airliner pilot. He said that on A340 and B744, a line on the NDs represents the shortest path between two points, ie. a Great Circle route. He also said that on older NDs (A300 or A310, I forgot which he mentioned) the line is not a Great Circle Route. So, could the "Lambert Conformal Conic" be the projection I am looking for ? Any help or pointers are appreciated.
