There is the Aircraft itself, and then there is the FMS!!!!! Still discovering new things almost daily, and puzzling over why things work in certain ways. I find it helps if you think of the aircraft crossing the Atlantic! I think it would be a good idea to pool resources of any tips/tricks used elsewhere, maybe people have specific problems that could be answered. The Honeywell Epic and FMS manual hardly touch the surface in telling you how it may be used in our type of environment.
