Yes, like these and others no doubt:

I think a combination of both for sure. The flight path of bullets gets very erratic when the mach barrier is crossed as they slow, after only 2 or 3 seconds of flight time. Add the sideways movements of the platform, caused by the firing of guns themselves. Another factor being any sideslip of the aircraft during the firing, introducing strong crosswind on the projectile. These would all combine to give a pronounced image to the viewer. __________________

Whoops Sorry Slipball, yes, those other factors you've already mentioned!

I'm really happy that this effect is modelled (visible on many gun-camera films from this era), but as Oleg has said previously all different types of round are modelled - previous tracers showed simple light-streaks with no smoke. I have no doubt that all are modelled accurately.

I'm a little bit surprised at some of the reactions to the spiral tracer smoke though - when the previous tracers were shown there was a chorus of voices asking where was the smoke?!?

I think the debate was about whether the smaller RAF 303 rounds should have smoking tracers or not. In IL2 they didn't while the larger rounds did.

I've seen plenty of footage of smoke trails coming from 303 rounds but I'm sure as Oleg says, different tracers had different properties and some types may have been smokeless.

I wonder what exacly mean and in which plane is such control:

Throttle War Emergency Power ??

I know 109 and Spit control panel and never see such thing?

I think generally this was achieved by moving the throttle to its maximum position. In some aircraft a thin wire was in place which had to be broken before the emergency power could be activated. This also told the ground crew that the engine may have been stressed in combat. I'm no expert though!

Bear in mind that there may be features listed here that will be applicable for future developments in the series. For instance there is facility to control 8 engines - obviously for the future as there are no 8-engine aircraft in the Battle of Britain.

Looks like the ship in this pic may be taking avoiding action?

Certainly seems to be moving to port. Nice! (a little difficult to say for certain admittedly, but another advance over il2 if so)
