Hi;I flew several test profiles this evening with ASA while monitoring the temps with FSUIPC. What I saw...with several default acft and the PMDG JS41 and RealAir Duke...was a clustered group of 1 deg C temp changes every few seconds as the acft approached the altitudes for which data is reported. For example, the temp at takeoff was 23 deg C...the temp did not change until approaching 3000 ft, at which time it ratcheted the temp down in one degree increments once every few seconds until it was at 14 deg C, which approximated the 13.4 deg reported at 3000 ft. Approaching 5000 ft in the climb, it ratcheted again, down to 10 deg C (reported was 9.4 deg). Near 11000 ft, it ratcheted down to -3 deg.There is no interpolation or smooth lapse occurring with changes in altitude...just these fairly large step-function changes in temp from one datapoint to the next. Is that how ASA is designed to work? I see a steady stream of data flowing across the LAN from my remote installation of ASA and FSX.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

Hi Bob,I am really not sure about this. I know we try and smooth the winds data, but the temp. data I don't know. It may be a few days, but I'll try and find out for you.Thanks,

Jim; I ran a SimConnect trace and the temperature data is definitely coming into FSX the way I see it via the set commands coming from ASA. I'm not completely sure it's a substantive issue...will have to do more testing. More importantly, I found what looks to be an error in the global weather set commands ASA is doing...highlighted in bold in my post in the thread "False TAT temperature indication with PMDG MD-11" in this forum. The temp and dewpoint in the last (highest) layer look like they've been omitted from the METAR string...I have a hunch this could be part of the bigger problem with rogue temps at cruise that some folks are seeing.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO
