The problem that you have with the compass in the aircraft is that it is not always correct, and due to game visibility limitations some of them can't be seen correctly at all in some aircraft.. this may not be a major issue if you have good visibility down to ground level and you are a competant map reader.. However, when blind flying and using time/ speed/ distance calcs etc to get from A to B, having an accurate bearing is essential.
I've tried using the in cockpit compass many times to add to the realism, but it is 'out' quite a bit at times. Another problem we have when we try to be extra 'realistic' in game is that we can't 'set' the compass to establish true accuracy anyway..
