Wind speeds at alt., 1/2 what they should be?

[contrailer 1]

I'm still using the original AS for 2004...yeah, I know it's old...(so am I) :( .

 

Anyway, until recently it had been working fine as far as downloading/representing winds aloft DIR/SPEED...as compared to actual forecast winds listed on NOAA,ADDs, etc.

 

Not sure how long it's been this way... but now AS downloaded wind speeds are about 1/2 what they should be at the higher altitudes. It's not the program itself not applying the proper speed from the downloaded data, it's the data itself(current_wx_snapshot.txt inside AS folder)that is showing these reduced speeds.

 

As an example, a flight today from DTW-ORD was showing winds in excess of 80-90kts at FL280(ADD forecast). I cleared all WX in FS/FSUIPC...first applied real-time FS WX(download winds enabled)and the winds were fairly accurate(topped at it's 99kt. limit).

 

Cleared the weather again and opened up AS. Wind speeds at altitude now were only about 40-50kts...those wind speeds were what was showing in the programs winds aloft section also.

 

So, did I change something(accidentally)....or perhaps it's something to do with using an old/outdated(like myself)ActiveSky???

 

Thanks

I did ASN FSX DTW JFK I had at :

17K  feet 282/72/-29C

29k 292/115/-53C

OK, thanks Vaughan.

 

...not getting anywhere close to that...

 

KDTW(from current_wx_snapshot.txt) for 062353z... top winds(FL390?) 263/43 -56.5

 

...my older(AS)version may no longer be interpolating data correctly...or ???

 

Oh well, FS  WX/winds appear OK...guess I'll stick with that for the time being.

 

Thanks again.
