As I mentioned a couple weeks ago now, not all aircraft in the sim are CFD-enabled. Surprisingly, this includes a number of stock sim airliners. Remember, CFD itself was not part of the core FS2020 sim at launch, and wasn’t even introduced until something like SU9 or thereabouts.
So not all aircraft are built and configured to actually compute their own aerodynamic forces using CFD in the sim. And if they’re not, there won’t be any wake turbulence.
“all the aircraft in the world are simulated with a new CFD…”
There was another interview where it was also discussed and explicitly promised to be working for every kind of traffic, multiplayer etc…
EDIT:
Here is (yet) another test I’ve tried, with the 172 G1000.
I already got snacks and beer in for this. You know, A380 pilots buzzing GA airports and heli-pads, dragging an EF4 horizontal tornado behind them. The videos and discussions should be fun.
I have seen it once in free flight. I got trampled on final by a jet just above me, and my plane got thrown around a bit. I think I was too high at the time for it to be mechanical turbulence, plus it happened right as the plane passed in front of me.
I haven’t tried but I assume having CFD visuals enabled would show the air being perturbed by other planes?
I taxied an ultralight onto a runway at JFK directly behind a departing A319 and took off essentially at the same time with zero issues. I’m fairly certain wake turbulence isn’t present with any traffic at all including AI and your own aircraft.
So according to the last Twitch Q&A, wake turbulence should be fixed now in the SU2 beta.
Can anybody confirm that wake turbulence is working now in SU2 beta, if you are in the SU2 beta? And you should be able to turn on the airflow visualization lines to see the wake turbulence, as Seb did in the last Twitch Q&A:
