known issue Holes on wings no drag?

There are several WT and CFD researches including our own CFD tests about the holes and their effect on lift and drag.  The results can disappoint those who expect "any hole must be noticeable". No, even multiple 12.7 mm holes or even hole up to 30 cm in diameter do not cause something catastrophic or very pronounced. First of all, because their area is only a small percentage of the wing area and, additionally, the air is reluctant to flow to these holes even if they are throughout the wing, because of inertia.
If the edges are bent outside the effect will be a bit more pronounced but still not very noticeable because of small area of the bent areas.
 

Out of curiosity was damage to leading and trailing edges looked at as well? Or only holes in the center of the wing?

Center. Leading edge is a bit different,  it affects more, for example, 8 holes of gun nozzles noticeable changes stall characteristics.

 That exactly what i am talking about, in DCS one wing damaged won't make any difference at all and this is exact case what you described that ice from one wing just randomly goes off and you are in spin. This is exactly what i have in mind. You are in high G turn and you got your one wing punctured by single 20mm,  since you are at edge of envelop, this slight lift reduction on damaged wing, will launch you straight in to spin, it is subtle but, you were on the edge.

That's either a plain lie or you really are absolutely insensitive to changes mate. Try the experiment I proposed, you'll see. The damaged wing always, always, always, falls first and manoeuvring as usual is just imposible once you have any damage. Last time I experienced in deep was a small internal "tournament" we had in our squad, P-51vsP-51 so it was the same for everyone, and the smallest damage you get is noticeable in your manoeuvring. But since you claim that it's up TO YOU trying it and prove something might be going on. Told you three times now, next is you do the test or just stop the nonsense.

@Ala13_ManOWar At first you are saying that damage at higher speeds do not affect plane only at low speed. Now you are saying that the smallest damage is noticeable. What is the smallest damage for you then?

[Ala13_ManOWar]

 Noticeable when you're trying to manoeuvre out of the straight an lever mate, read it all, not just what you want. In fact that's equivalent to lowering your airspeed, have I to explain that also?

Just test it mate, or don't and SHUT UP. Your choice .

This is already reported, while the effects are not 0 its not perfect either so its reported to be reviewed on all aircraft. thanks.

I flew the Spit the other day and was promptly shot down. Observing the AI fighting in the F2 view I noticed a FW-190 flying around effortlessly with only the left elevator intact! So there seems to be a problem.

Talking AI is another issue as they use a different more simplified FM than us, but this will be reviewed once the GFM lands.
