I have FSX running on PC1 with a full version of FSUIPC and WideFS.  I have PC2 running RC4 via WideFS.  I have PC3 running ActiveSky 2012 via Simmconnect.  I am using DWC and I always get the wrong destination wind direction and velocity.  Is there some kind of configuration I need to do between all these products?

There is a conflict with FSX in the way the weather is controlled by apps like Active Sky. In FSX weather apps have to use Global Weather with DWS. This means that the weather environment universally takes on the immediate area around you aircraft location. As you travel that environment mirrors your aircraft locations weather. This also plays havoc with ai patterns. When you contact approach RC sees the weather where you are located, not at destination. FSUIPC was modified to report ATIS from AS's destination METAR directly, not using FSX's weather engine.

 

FSX supporter for RC Bobbyjo recommend using the AS feature for FSX destination weather lock to weather for the last few miles (at approach contact time) remains stable for the patterns established for the spawned ai. That will help in avoiding ai runway assignment conflicts as monitored by RC.

 

Be sure your fsuipc and Active Sky have current versions.

 

This conflict is not in FS9. It is a restriction in Sim Connect which AS uses and in part FSUIPC.

 

Please see the pinned thread regarding this.

Thanks for the info fonzie but I can't find the pinned topic from Bobbyjo. Can you send me the link?

 

Thanks.

That thread is not pinned. The pinned one I wrote based on BobbyJo's comments and those of Pete Dowson (fsuipc.dll developer) who worked with the Active Sky hi-fi sim developers. The one I referred to is Attention ASE users.

I tried setting Active Sky to use FSX destination weather lock and DWC.  The destination WX is close enough to what Active sky shows but when I tune ATIS in RC prior to arrival I get all kinds of erroneous data.  

How far out from destination are you tuning?

Also, be sure you have a current fsuipc4. It is well beyond the version delivered with the software distribution and that can affect the reported weather.

I have the latest FSUIPC and I tune 50 and 100 miles out so I can compare any changes.  Both show the same(whats reported in Activesky)  

 

I opened a ticket with active sky yesterday.  I was noticing winds are  wrong compared to METAR.  I think my problem is with the weather engine.  I was testing today and i watched the wind swing 360 degrees 3 times in 20 minutes.  I think it may be related to the latest beta SP i installed.  We shall see.

Hi,

 

I have used Active Sky for years without too much trouble,using DWC set up.I have to say that I never tuned arrival ATIS until 50nm to go having first noted what the destination weather was doing prior to departure.

 

Over the past few months I have used OPUS and even then you have to ignore RC ATIS and use the reported winds at the destination to select arrival runway.For siome reason the upper winds at the destination are picked up and not the ground level winds.The ATIS does report correct winds after some time.

 

I have tried the AS beta and was not impressed.

In FSX Global Weather is mandatory with DWC. If you are getting upper winds that is the wind around your current aircraft location applied universally with the FSX world.

 

The last I was informed some time ago, the developer of fsuipc4 worked with the developer of AS so AS would be automatically detected and then an RC call for ATIS would get the destination METAR reported winds, not the winds that instant at destination. This does not affect the weather occurring at destination as you fly in, just the ATIS report to RC. Therefore ai patterns could be "flaky" due to the constantly shifting winds from the updated aircraft position effects.

 

I have contacted the person from the RC team that worked with the AS and fsuipc folks alerting him to this thread.

The developers at AS explained a few things to me that weren't apparent. It seems metars indicate true direction of wind and FSX reports it as magnetic. +/-30 degree variations occur based on location. Secondly with ATC wind lock on, winds will always be a mimimun of 6 knots in fsx even if metar report 1knot or even 0. Lastly when direction is variable or calm Fsx will and does show full 360 degree wind shifts over short 1-5 minute time period. I was looking at calm winds and metar showed 180 00. Fsx value was 360 06 and I watched the direction swing 360 degrees all this while stationary on the ground. I was also seeing 345 10 and fsx would display 330 10 based on magnetic variation.

 

This all plays almost no bearing into what was happening with RC. It seems the global WX when flying with DWC is what you are in at the time. destination weather was always close to global +/- magnetic variation. FSUIPC logs confirm that and match what RC reports. I traded email with Peter awhile ago about this in general terms and he didn't think FSUIPC had anything to do with it.

 

I can provide log anyone interested in taking a closer look.

http://forum.simflight.com/topic/66748-destination-winds/?hl=atis old but still applies to all applications retrieving weather via fsuipc4 as does RC4.

 

http://forum.simflight.com/topic/73850-fsuipc-weather-interface/?hl=atis#entry452969 Feb 2013 includes effects of weather smoothing, Global mode, etc.

I guess it's as good as it gets.
