I agree with all the feedback here so far (yes, even you, Kraken :) ) in that it isn't really that important how a tumbling plane falls when it's missing a wing, but considering all the complex properties of a wing (lift, collision shape, etc) it surprises me that mass isn't one of them. Anyway, I guess it's no good complaining - as others have mentioned it's probably OK to dismiss the strange angle as a result of uneven ground or hidden objects in the grass.

Yep definatlely something wrong with that B17 in that last picture right there:grin:

On a serious note, this is rather weird and should be implemented as it is a simple law of physics, of course there are situtations where this occurs, but in IL2 it is a little to frequent. I hope they look into it, but I doubt if this will effect the actual FM of the plane, it's almost impossible that they would leave out gravity..

Actually, it could!

In the virtual world what is displayed is not necessary accurate to how the vehicle handles!
To reduce complexity developers often take shortcuts and set a point X to represent enough damage on wing as to render it "gone", but the FM still sees enough that it is possible to fly the airplane (although flying sideways).

Omfg, does it really matter how the plane came into the position it is in?...

No. What matters is that it is defying gravity by remaining in that position, and the implications that the damage model does not care about center of mass.

Completely unrealistic, indeed. ;)

Like this obvious fake:

Actually, this looks like a crashlanding where perhaps the LH MLG has not collapsed or the skidding has flattened the fuselage so much it's not perfectly circular anymore and rests on the "flat" area instead of rolling over. Seeing that we cannot see wether gear is extended or not, we have no conclusion yet, but you make a good point.......

... which we must prove to be blasphemy! :) :p

So the wing weighs more than the center or what are you saying, it should've tipped on the wing?

TheGrunch 02-11-2011 03:47 PM

I seem to recall that we were told that the centre of mass changes depending on fuel flow (obviating issues like the nasty P-51s in IL-2). Perhaps this was ignored because it only affects terminally damaged aircraft. Ought to affect aircraft that have only lost wing-tips and ailerons and rudders, though, ideally.

The airplane, an ATR-42-320, came down 300 feet short of the threshold runway 17R at Lubbock Preston Smith International Airport, TX.
