Wind direction discrepancy at altitude

Featured Replies

Just completed a two-hour FSX flight from KPHL to KPBI in the default Lear 45, using AS 6.5 I have the registered version of FSUIPC 4.01 and Wide Server 7.Before beginning the flight I loaded the FSX flightplan into Active Sky and processed it.Winds were right on the money at my departure and destination airports, but way off direction-wise in cruise at FL 380. In general, the wind SPEED was always quite close to what was currently showing in Active Sky, but the DIRECTION was rarely even close to correct, varying anywhere from 90 to 180 degrees from A.S.I realize that this may well be a FSUIPC problem, as I know that Peter has not yet inplemented wind smoothing in FSUIPC Version 4. This is all very much a work in progress... just thought I would bring it to your attention.Jim Barrett

Hi,Thanks for that! You will notice this in the FSX Compatibility.txt file. We are glad that you discovered the same thing as we did.Thanks,Jimhttp://www.hifisim.com/Active Sky V6 Development Team Active Sky V6 Proud SupporterHiFi Beta TeamRadar Contact Supporter: http://www.jdtllc.com/AirSource Member: http://www.air-source.us/FSEconomy Member:http://www.fseconomy.com/

Hey guys, was flying Eaglesoft's new FSX Beechjet at a cruise altitude of 19000 from KSEA to KRDM. I have registered FSUIPC 4.02 and was using ASV 6.5 for weather. I was also getting those irritating speed spikes up and down 30-40 knts. at a time at 15-30 second intervals. I at first thought it was the jet, but remembered that this happened in FS9 before Pete Dowson or you guys did something to correct the problem in FS9. Is this lack of "wind Smoothing" the cause??. I did contact Pete and he said at present FSUIPC 4.X has no connection to weather parameters at all.Randy Jura, KPDX

Hi Randy!From the same text file:"2) SmoothingFSX does not support direct ambient control of weather variables including wind direction/speed and visibility. For the most part, FSX has improved its own internal smoothing yet some limitations do exist."It is something we are going to need to wait for from MS, or engineer our own fix.Thanks!Jimhttp://www.hifisim.com/Active Sky V6 Development Team Active Sky V6 Proud SupporterHiFi Beta TeamRadar Contact Supporter: http://www.jdtllc.com/AirSource Member: http://www.air-source.us/FSEconomy Member:http://www.fseconomy.com/

If FSX will not allow for control of wind direction, speed and visibility, what's the point of ASV for FSX? ... do you mean that ASV is not controlling or passing along those things to FSX?Randy Jura, KPDX

Hi,Please read the txt file, it explains all this.FSX's simconnect API has a bug which prevents setting aloft wind directions in some circumstances. All other parameters are fine. We are awaiting a fix via a simconnect update which has been speculated my MS. Hopefully it won't be much longer, and when it's made available, wind aloft directions should be proper without any further update of AS required.Best,

Hi,One more point.. although FSX doesn't support "ambient" control of such variables, we can indeed control them via the station structures. Station weather = what is programmed for a specific location/wx station. Ambient weather = what is actually depicted in real time at the aircraft position. It's the ambient weather we are unable to control, but station weather control is doing fine in most circumstances. Things will be improving for sure beyond this as well..Best,

Whew!!....good...I must apologize, I usually have read all accompanying text files for installs, but that one eluded me. OK, so one more simpleton question then, I would assume at some point that wind smoothing will somehow be reinstated into the future?, as it is obvious there are still vulnerabilities to such things out.Randy Jura, KPDX
