unrealistic wind shifts

Featured Replies

Hello everyone,I use Active Sky Advanced with SP1 (build 433). On every flight, no matter which aircraft, i receive unrealistic windshifts during take-off, cruise and approach. My latest experience was as followed:I did a flight from EDDF to OMDB with the PMDG MD-11F. I do not use DWC, because of the bug which causes add-on aircrafts to slalome courses etc...Everything went fine just after take-off, than after about 1 min. the wind went crazy. Direct opposite wind changes within milliseconds, for example wind was 280/32 within a blink of an eye it was 100/32 then again 280/32 and again and again and again. This happend all the way up to cruise level, then stopped for aprox. 30 mins. Afterwards it started again:wind changes with direct opposite directions but even more severly! with wind-velocity of about 96 knots coming from head and then from tail and again from head direction is absolutely out of nature. As i am no expert in programing i can only presume it maybe a conflict between weather stations? It is even more frustrating when it happens during approach: head winds directly following tailwinds and again headwinds make an decent approach impossible.This has nothing to do with windshears as this phenominon follows me throughout my flight.I can't fly properly as my aircraft either stalls or overspeeds the whole time.My settings: Download interval 12 mins.dynamic rate of change: 30%DWC is disabledi have only unregistered version of FSUIPCTurbulence on aircraft disabled within FSXThank you in advance for any suggestions or help.Conchi

Hi,You either need to enable DWC or use the registered version of FSUIPC to control wind shifts. The Revisions.txt file has more information about this.Thanks,

Thank you for answer JSkorna but some things remain unclear:Does that mean i have to choose between two issues? I mean, when i use DWC i will certainly experience your so called "s-turn hunting" as said in the .txt .In addition, in the revision.txt it is recommended to disable the wind smoothing of FSUIPC ?! So either s-turn hunting or crazy winds? Is there no other way to omit those two issues and still use ASA? I really like that program but both suggestions are only a switch between two rather big issues.Conchi

Hi,Have your tried with DWC On?Thanks,

Hi,Have your tried with DWC On?Thanks,
Yes i have. I experience s-turn huntings with every PMDG aircraft, Posky aircrafts ( not as severe but still apparent ), Realair Duke/SF260 as well as the Lotus L-39.Meanwhile i found another strange issue. I did the same flight as posted again and the ATIS at OMDB gave me a temperature of -48 degrees celsius. This happened to me just once before while during a flight from WSSS to YBBN where ATIS gave me ridiculous airport information.Does ASA change anything concerning ATIS?However, DWC had no effect in solving the issue with the constent crazy windshifts but added the s-turn problem :( Is it somehow possible to change something in the settings so the windshifts can be weakened? Anyways, i think the root problem is a conflict between ASA depicting weather-stations with contrary wind-data, maybe. I am by no means an expert but i found out that the windshift problems aren't as severe over the great oceans as over land, where most weather stations are located. This issue happens extraordinarily often in the US, especially when flying towards KORD form Europe and entering the US-Airspace from southeast canada.i hope this information can help you out a little bit.Conchi

Hi,If the ATIS issue was with DWC On, this is normal. ATIS will report conditions at your current location.As far as the other issue, it is going to need to be a trade off call on your part. With these wind sensitive planes there isn't a way to take care of both unless you disable turbulence all together.Thanks,

Ah, alright, thank your for making it clear with the ATIS issue.How could a trade off look like? I see no way to decrease eather the s-turn or the windshifts. Is there a way somehow to deal with it? As i interprete from your post, there is no direct way to solve the problem so i would like to know how to deal with it.Maybe a workout with ASA settings?I really have no clue how to handle that at all. Any recommendations would be great.Conchi

Hi,DWC reduces wind shifts but can mess with the ATIS system.FSUIPC reduces the wind shifts as in the registered version you can control how quickly the winds change speed and direction.The S-turns are the sensitive plane's way of reacting to the wind shifts and turbulence.Then one ultimate setting change in ASA is to disable winds aloft. I know not very realistic, but that is the way through the ASA settings.Thanks,

alright, thank you for the numerous possibilties! If you mind i have one question concerning the reg. ver. of FSUIPC. When it controls how quickly the wind changes and the velocity and i alter it, will i still experience windshears where possible? Or does it override wind changes in basically every way possible?

Hi,Before I answer, what do you mean by "wind shear"? Many have a different expectation with this term.Thanks,

My definition of a windshear would be a significant change in wind speed. For example i land on a fictional runway with windspeed of say 10 knots and all of a sudden wind changes to 50 knots for a short period of time which would eventually effect my airspeed in a dangerous way, inducing a stall or overspeed. That would consequently make my aircraft to either overshoot the rwy or i crash long before.Btw. i have just installed a reg. vers. of FSUIPC. Maybe you could give me an appropriate setting for the "windsmoothing" options which goes well with ASA?Conchi

Hi,Those winds would be smoothed out by FSUIPC.For settings look at that Revisions.txt document for a good place to start. Then adjust things as you find necessary.Thanks,
