Hi Jim, getting quite bad wind shifts on ocassion at high levels with the latest ASE build on FSX (when I say bad, enough to knock my level-d out of VNAV, not turn it upside down). I know the solution is DWC, however I use Real Atis too (marvelous BTW) and using 'global mode' makes real atis not function correctly (it told me the weather at KMCO was -53 degrees yesterday with DWC enabled in global mode!) it's my understanding that ASE in 'station mode doesnt provide or doesn't do an excellent job at wind smoothing so I looked to FSUIPC. I realise I need to check the box 'allow changes to FS own weather' and then select the wind smoothing option, which I limited to 1 degree every 2 seconds and it seemed to work quite well. So my golden nugget question is this:- will this setting affect thermal generation and/or wind shear effects at low altitude (i.e landing in gusty wind), is it one of those FSX trade off situations where you can only really have one or the other. I'm led to believe this is so but just for conformation if you would. I think i'd rather have the high wind shifts than lose wind shear and heavy turbulence. Thanks.Kind regardsMark

Hi,Yes, that is the trade off. Those other events would also be smoothed by FSUIPC. FYI, you might want to read through the Readme document in your ASE folder and try some of the suggestions contained there for this issue.
