I am not sure I am reading my situation correctly, but it seems the wind sock is 'backwards". Help me confirm.

I just landed and parked beside the wind sock (plane is not moving)  My surface wind is 030 at 6 with some gusts. (as per my weather window with a live METAR (Unreal weather))  So the wind direction is 30 degrees and the vector is pointing to 210.  I read that as the wind is out of the 030 and blowing towards 210.    My Garmin wind indicator is showing the wind bouncing around between 29 and 31 degrees and from 4 to 6.5 knots (expected with some gust). The Garmin Wind vector is roughly pointing to 210 which matches the the wind settings window.   (coming from 030 and blowing to 210).  I think of the Garmin wind vector as the direction my AC is being pushed.   The windsock outside my window has the opening facing 210 with the tail of the sock lightly flapping towards 030..  which says it is blowing out of 210 and towards 030.  This is opposite of what I would expect.   I know I am getting old and slow, but... am I reading this wrong?

RESOLVED:  This problem is an issue in the free scenery "Bad Hersfeld".  I have filed a GitHub issue to alert Chris of the problem.  This is still a GREAT Scenery.

Seems backwards to me.

The other night the wind sock was doing this and I was trying to land with about 9 knots of tail wind.  (Circling the field and looking down at the sock). Then I checked the weather and thought something was wrong. I was too embarrassed to ask if I had misunderstood the wind vector all these years.   

So now I just logged out and back in, selected a different airport and the wind sock is back to behaving like I always thought they did.  (see below). Since this has happened a couple of times and seems to "clear itself up' after a relog or relocation... maybe I should submit the first picture to the ZenDesk.

Regarding wind direction/speed and wind arrow indication there are some issues.

1) There is no way for the computer to calculate wind direction/speed on the ground where the a/c is parked (stationary). The airplane needs to move before it starts to calculate wind bearing, speed and direction with respect to display orientation and heading track reference. 

I don't know these units at what speed start the calculations to be able to be displayed, on our airplane it needs at least 100 KTS before it shows anything and at lest 5 KTS wind velocity.

Somebody with Garmin Handbook can check that speed (I would say at least 20 x 30 KTS)

2) I put some pictures taken out off JFK 31R where you can see the wind-sock, wind direction and speed and you can see clearly from the first one wind is 040/24 and wind-sock is showing correct. 

What is incorrect is that the computer cannot calculate the indication on the left side to show 040/22 while the aircraft is not moving.

3) Next 2 pictures show 220/24 and 310/24, both are correct indicated by the wind sock except for the wind direction and speed on the left pilot display while the airplane is holding still on the ground.

We still need clarification from the Garmin Handbook for these units regarding what is the minimum TAS before the indication will show.

I hope that will clarify your concern.  

 

 

Roger all and thanks for the information, but I was comparing the windsock to simulated wind (weather page)  This is not a Garmin issue (or an MSFS issue). The Garmin indicated indicated wind was the last calculated wind while taxing off the runway, which just happened to be VERY accurate. The issue is,  the difference between the Simulated wind (weather page) and the windsock being 180 out from that.  As noted above, this problem was identified with the add on scenery for Bad Hersfeld. (windsock misaligned) this was the only place it occurred and the wind sock 'righted itself' when the scenery was uninstalled.  When I reinstalled the scenery, the problem returned. I contacted the creator on GitHub. 

Killtehspam, Thanks for those pictures.  They confirmed that I was not loosing my mind.  

After building a few sceneries with windsocks I think I can confirm that the simobject I add to the scene was 180 degrees off by default. A short test with the new update and the new SDK it seems they changed it. Will do further tests.

good to know that there was and hopefully is not any longer an issue with the windsocks. I recently flew somewhere were I saw 2 windsocks, one left and one further right of the runway and both swayed in opposite directions. Still did not find out how to take screenshots in MSFS so it remains hearsay 😉 but I will keep an eye on that next time I fly

I have the same issue in my scenery. What did you do exactly? Replace object and rebuild?

I rotate the windsock to 0 degrees and rebuild the project.
