Its my understanding that the new damage model is going to be much more complex...
And from what I remember, damage modeled within a specific mechanical system will have consequences (triggers maybe) that will effect "other" mechanical systems within the aeroplane (I think I remember reading something about this in a "Q&A" with Oleg)...
I think that Oleg is going to save the specific features of the new damage model for the game release...but I would love to be proven wrong.
p.s. Nice reading Azimech, thanks.
