I don't know if it was already reported here but I found that temperature aloft at FL300 has always a significant departure from standard atmosphere.Here are some values I just had on my last couple of flights:First is a climbout from edinburg (EGPD) with today's weather (14Z):Alt / OAT / ISA DeviationFL240 / -28 / +4FL270 / -30 / +8FL300 / -32 / +12FL320 / -40 / +8FL340 / -48 / +4FL360 / -51 / +5Note the unrealistic 16

Hi,If you go here:http://weather.uwyo.edu/upperair/sounding.htmlyou will see that the data is good. I suggest updating to B142.Hope this helps,JimActiveSky Supporthttp://www.hifisim.com/images/as2004proudsupporter.jpg

Hi,I am making an adjustment to the data process which should help here. I was able to confirm that FL300 data could be handled better. The data is close, but there was room for improvement, so there you have it! Let me know if this improves things for you - it should be active on new downloads in about 2 hours.

Hi,I'm currently flying an LPFR-ENGM leg and first observations during the climb off LPFR were good: no more abnormal departure from ISA at FL300, the ISA departure gradually fell from +5

Hi,Thanks for the positive report!!Hope this helps,JimActiveSky Supporthttp://www.hifisim.com/images/as2004proudsupporter.jpg
