I've followed all the beta's through. currently have build 90 installed.My heavies through to lights are still being downed by WT generated by light single engine props.This simply does not Happen! I'd expect it the other way around but 9 times outa 10 i encounter nothing.SettingsWake Turb Sim CheckedIncreased wake effects unchecked.WT simulation was a major factor in my decision to purchase. It needs to be looked at carefully and improved.

Hi,First, I must say, that no reports of any wake problems were made after B86. It is very hard to fix something when we aren't aware that there are any problems. Please don't hesitate to speak up, especially during public beta cycles. That is the entire purpose.Second, are you using the registered version of FSUIPC? If so, check your AI/TCAS ATC ID setting. This should be set to FLIGHT so as to provide AS2004 with the proper data to distinguish between aircraft type.Third, by coincidence?, I happen to be working on future wake enhancements at the moment. Let me say that in the near future the wake turbulence engine will be completely overhauled and I'm betting that you're the exact kind of user that will really benefit from it. Instead of determining aircraft type from unreliable FSUIPC ATC Flight ID strings, we will have our own editable text database of aircraft types and associated wake generation parameters (including overall size, intensity, and dissipation). Instead of a single "closest" aircraft condition check, we will be monitoring all AI aircraft at regular intervals to synthesize an entire wake "picture" complete with multiple, moving, dissipating trails that are effected by winds. Resolution accuracy, which currently can be +/- 500ft or more during condition checks, will be improved to be less than +/- 20ft.So, in conclusion, we are working very hard on improvements in this area (and dozens of others!). While the future enhnacements don't help you now, I will do everything I can to help make things satisfactory for you with the current version. Check your FSUIPC settings here, and please report back to me directly via e-mail at [email protected]. If that doesn't work, I will make changes as required to improve things and supply you with test versions so you can confirm.Hope that helps!-Damian

To confirmyes i run registered FSUIPCand yes "Flight" is selected.The improvements you mention seem to be headed in the right direction. it's not the ammount of WT effect generated thats the problem, it's the type of aircraft whcih produces it which is.Looking forward to the changes

As I mentioned in another post, the WT did not dissipate in a timely fashion when a strong crosswind was present. Horizontal WT drift might be too much to emulate but it also could possibly make parallel runway landings interesting.I work under the finals of 12L/R at KMSP about 15 to 20 miles from the thresholds but I notice typical heavies followed by commuter jets and props perhaps seperated by two miles for each approach during string-of-pearls periods. I was doing something similar in FS following in a CRJ200 but with about a four mile seperation according to TCAS but got hit with something a couple of hundred feet before touchdown (final MR1 build 90).Anyway, your description of the next WT improvements really show your dedication to emulating real environments as close as you can within FS limits. Thanks for the current improvements and also in advance for future changes.

I join the group that says the WT are not very realistic: in busy airports i find the WT appear casual, without any real clue to the "generator" of them.Near airports you just sometime happen to have some turbulence that's all.Or at least this how it looks to me, when flying.Obviously there are more subtle algorithms for them ;)

WOW! That new wake system sounds wonderful...One other thing for those with issues: Jim has posted a number of times that it might help to alter a parameter in FS9.cfg - Turbulence_Scale (or something to that effect) to something like 0.3 or 0.2 instead of the default which is 1.0. Have you guys made this change? Please correct the details if they're wrong, guys. I thought this was in the FAQ but I couldn't find it...didn't look too hard, but still.Best,sg

Hi all,Thanks for the good input.I have decided to spend some more time with the current version of the wake simulation and refine it a bit more for better realism. Some suggestions that I hope to incorporate:- Wake effect intensity slider or numerical 0-10 value setting- Automatic verification of appropriate FSUIPC AI/TCAS settings- Automatic detection of lagging AI data (don't launch the effect if the data is more than 1 second old - this appears to be the cause of the 'non-dissipating wake trail' that some have experienced)- Better computation of generating aircraft size and flight path- Better resolution of position vector and altitude condition checksNo time frames on this yet, but it should premier in the next official AS2004 update (MR2). As mentioned, we are also working on a complete re-design of the wake system which is further out.Thanks again!-Damian

THAT turbulence scale refers to weather induced turbulence such as wind shear, violent drafts with TRWs and towering CB, etc, and that change as you noted works exceptionally well with the few models I fly - first tried it in FS2K2 and also now in FS9 - from light GA to commuter twins and on to almost heavy turbojets.WT is not affected by this scalar as posted elsewhere in this forum some time ago as it does not generated by the weather engines manipulated in FS9 (AFAIK).

And thank you again for pursuing this area within your excellent product.With the release of the AI SDK and Pete's improvements with AI reporting and control, these events should hopefully make your tasks easier.

You are correct, sir!Hope this helps,JimActiveSky Supporthttp://www.hifisim.com/images/as2004proudsupporter.jpg
