I agree with Polovski & Interlocutor on this, theres many variables which would reduce the range of your vision flying a/c of this time period, vibration, cockpits open to the elements, size of A/c ,dirty goggles, smoke from ground battles etc these all have to be taken into account.
I also fly without TAC, but sometimes have the labels turned on in case theres a good screenshot opportunity - but only for that reason,
I invariably end up as a lawn dart, - I fly the BE2 a lot, which is just cannon fodder,
I'm happy to end a mission having completed all the objectives & still be alive, never minding about kills...
He who fights & runs away..... can get his ar*e kicked another day!!!
