ooohhhkkkaaay, what if you want to hold the plane in a turn?
shift-x still puts wings level!
Like I've been saying, go to 'off-line practice' then up a 111, catch up to the drones flying circles and try to shoot one down with front guns.
Another example, offline: flying a 410, line up under one of the turning bomber drones, then go to gun, fire! stationary target? NO! Yes would be if not for 'auto-level.'
Get the plane going on the correct vector / path such that you will have a nice stationary target (relative to you) to fire at.
The pedals thing to sway the nose helps, but its not enough, and still the nose bounces left and right too much anyways.
Doing damage to enemy plane requires damage, which requires AIM, which requires steady shot, which requires steady target relative to you!
