Is it realistic the way you can hear a plane coming up on your six from .8km away? It seems to me that I can hear a threat behind me before they are in firing range and gives me an advantage that I do not think is true to life. Talking WW2 fighters here. This is a double edged sword as I am flying the FW190 right now, so my tactic is to dive to gain speed, come up on the rear, lower if possible and blast with guns when I am within .4km of the target. But of course he can hear me and pull off. On the other hand when I am cruising at altitude I can hear fighters that zoom up to my rear and lower, even If I can not see them I know to turn off and every time I have been right, I don't always survive, since I can't manage to escape a P51 very well and they can always try and engage a turn fight that I always seem to lose, however I am new. My issue is, it seems it would be a loud place in those cockpits and you would not be able to hear an enemy plane, maybe if they where 20m behind you but certainly not from almost half a km away. Thoughts?
