Hi, I have just downloaded Beta 3 and I notice something strange in the wind direction (see attached screenshot): it is 170 degrees on the ground and 346 degrees at 3000 ft? Isthat possible? I try flying at 3000 ft and indeed the wind direction is still close to 170°. I use DWC. Thanks.

 

 

Sorry, I think that's correct, it's a warm front just arrived at low altitudes with southerly winds, while at upper altitudes there is still cold air with northerly winds. Flying at 3000 ft the airplane nav display wind vector slowly changes from 170° to 340°.

Hi James,

 

While there may be a problem, it can be quite normal. The surface layer tends to turn right (about 90 degrees-ish on average) from the aloft average directions due to surface friction. In this case it is even further shifted, perhaps a local weather pattern phenomenon, maybe influenced by terrain. AS2012 extends the actual depiction of the surface wind up to about 4500ft in DWC mode order to keep consistent departure/destination based on the METAR (and assist with AI runway selection consistency) which is why you're seeing 170 up around 3K. We've received request to allow this to be configurable so that low-altitude flyers (or anyone) who desire the 3K level to be prevalent can make it so, and we are working on that.
