Only turbulence I want is prop wash...
We have the smoke trails for individual engines, which are roughly the size of the prop...
So say they follow pretty much the same path as the smoke would do...if your plane comes in contact with the wash your plane pitchs some and shakes a bit.
I've heard that after a group of B-17's took off from the English bases during WWII, it was like taking off into a hurricane with all that turbulent air.
Wing drops, accelerated stalls...ahhhh. And yet another weapon for buffs and the "I'm out of ammo!" crowd.
Only possible bug I see is people landing at an enemy runway after the ack is down, parking reversed to a spawn point, and blowing over planes as they tried to take off

I had the pleasure(?) of taxing behind the B-17 'Thunder Bird' on more then one occasion at Scholes field. Those dang things will blow a small plane backwards if you aren't careful.
