Wake Turbulence has little to no effect

Well just uninstalled SU2 BETA because for me it’s in un-testable state. Spent nearly 4 hrs with around 20 mins of actual flying. CTD’s and unable to start flights are the main cause.
However when tested, tried the wake turbulence feature when flying my TBM 850 in VATSIM (observer…) and followed several traffic , all with the DEFAULT traffic models ( no FSLTL …causes crashes ).
See in the video below… any movement is pilot induced..no impact on the aircraft.
Another side note, I would expect wake turbulence to be enabled by default, now it’s a bit “hidden” in the menus, along with finding the option visualize it.
Anyways, that was my attempt to get bumped and shaken by the heavy traffic ahead…

I tried to test if wake turbulence was working in Beta 2 . Made sure it was on & visualization shows some turbulence but has no affect on the plane. Is it just that it doesn’t happen with AI planes . See attached video to show what i mean . Wake Turbulence - Not working

oh, it definitely works! have someone fly a skycrane in front of you and turn on the visualization. even > 1 mile behind i was getting tossed. however, on the ground with the skycrane hovering above there was no effect.

I don’t think wake turbulence works with injected traffic like VATSIM. Only multiplayer and maybe AI. At least that makes sense to me.

Sorry that doesn’t make sense to me at all…we can clearly see the visualized wake, they promised it will work with EVERY plane as it should.
Perhaps atm it works only with helicopters as mentioned here ,but that surely either not fully implemented/released to the beta yet, or still broken unfortunately.

How would it work as an observer on the network? As far as other vpilot clients are concerned, you’re not visible. So it probably deems the aircraft non-existent.

Can you not get someone to go with you to a quiet area and do some circuits to test while not in observer mode?

It’s also possible vPilot hasn’t been updated to take into account the wake turbulence feature.

That’s much simpler than that… (saying this as a long time developer and vatsim user). vPilot injects AI/Multiplayer traffic for every vatsim traffic, it’s relatively very basic data that injected into the sim… Observer affects how the user appears to others pilots and controllers. vPilot has no knowledge of wake turbulence nor it should. I did the quickest test I could given the unstable nature of SU2 BETA for me.. and I needed a heavy traffic Infront of me.
Anyways, this is really unrelated to VATSIM. As seen in other posts, the same problem applies to other AI/multiplayer aircraft, the wake turbulence currently don’t work.

Do you have the same issue if you follow the OP’s steps to reproduce it?
• Yes

Provide extra information to complete the original description of the issue:
• I just had a play around with this, in the COWS DA42TDI. I was using slew mode to constantly put myself behind jets that are taking off. With proximity air flow visualisation enabled, and no where near the jet I would see smooth blue lines of air around me. It wasn’t until I was very close to the jet that this pattern of air was disrupted, and instead of long blue lines they were much shorter cyan lines pointing in all directions. The effect was not great, and I was easily able to stay behind it even flying with mouse, and keyboard. It’s there, just not very strong.

A report here is that the latest 1.4.11.0 patch has fixed this: https://www.avsim.com/forums/topic/668455-new-msfs2024-su2-beta-update-14110/#findComment-5427805

Anybody else testing this to confirm that wake turbulence has been fixed in 1.4.11.0?

Will hopefully have time to try this out tonight. Under previous betas I did, and found that there was disruption to the atmosphere around a big jet, but it’s sphere of influence was in its immediate vicinity, and not very strong. Close enough that I might be attempting to refuel. You could see it with atmosphere visualisation options enabled.

I’ve also wondered whether planes that have CFD options enabled experience it differently to those that don’t.

So far I’ve been trying to chase airliners in the C152 and various ultralights, and have gotten seriously knocked around once (sudden left or right roll to a 45+ degree angle and needing immediate correction not to crash, quite fun) but so far only from another player’s aircraft. Still trying to repeat the same result with live traffic, I do see the same shimmery lines depicted so I don’t see why it shouldn’t be possible. I’ll update when I have further results.

a 767 taking off knocked me around in the C172

Ignore the tag saying 737, the model matching still isn’t great

Did some testing in the Jetson One, literally hovering in the approach path of KSAN, but little or no effect from landing airliners. And whenever one taxied onto the runway to take off, it just taxied off again a few seconds later, maybe because the landing planes never stopped to give it a chance. I’ll have to find another airport where airliners are taking off.

Wake also works with BATC injected aircraft, which aren’t normal AI, so it should theoretically work with VATSIM as well, but I’m not part of the network so I can’t test myself.

Try RJTT, that’s where I’ve had the most luck. OMDB works well too

Ok did some testing with the current beta. Something is happening now .just still very weak and very mostly in very close proximity.
Needs more testing for but for now used my go to TBM 850 (CFD prop), and tested VATSIM (A320) and as well as real-time traffic (A340).
Only when traffic got slowed just before touchdown and in extreme formation flying, blue angle style… I got some rolling force, and still not super strong one.
So ingredients are there but maybe more tuning or factors involved… will keep checking…

True, my strongest results so far have been in an Aerolite 103 ultralight. Even in the Cessna 152 I hardly feel anything.

It seems you are directly behind the preceding aircraft, wake turbulence sinks below the aircraft and the two wingtip vortices move appart about 5 kts. To experience wake turbulence you need to be slightly below and to the side (at least in real life).

Edit: I see its a video now not a picture. Yeah you definitely should have hit wake there.

To illustrate, I hit wake turbulence one day behind a medium (A320 or B737 don’t remember) while intercepting the glide slope from below with a slight crosswind, we were vectored a bit close behind, maybe 2 / 2.5 nm and upon hitting the wake bank angle increased to 30 degrees in an instant and almost full roll input did not stop it. That was with an ATR 72. So yes, sounds like it is way to weak.
