Maybe it's a Mexico thing. Right now I'm cruising from KSMF to PHOG at FL360 with a TAT of -17 c. Target and ambient are both at -46 c. I'll do another Mexico flight sometime soon and see what happens.

Tried deleting the PMDG DLL files from the FSX file. Still not working. I am currently stuck at FL260 because my plane will not climb at +30 c.

I'll try that PMDG fix from a post I had earlier this month. Forgot about that, and we'll see if that works tomorrow. Any update on that?

I was flying out of Mexico City and the TAT kept climbing as I climbed. It was +33 c at FL200. I was having a hard time keeping the aircraft going up. I'm a RW air traffic controller, so every once in a while I get to ride up front in the jumpseat, and last weekend, I paid special attention to the TAT during the flights when I went down to Minneapolis. It was nice to see that, at a cruise of FL350, the TAT was around -28 to -33, which was around the amount I was getting in earlier version of OPUS at -25. I'm using version 2.70.8 and FSINN. I have disabled all weather on FSINN. Is there something else I should try? It's frustrating to have temps that high...

Got the latest Beta, and deleted the PMDG dll as described. Worked out well. The TAT was around -25 at cruise.

Just got the new Beta. I'm flying in California right now, struggling to climb because it is showing +21 at FL270. It stayed around +19 all the way from about 10000ft. I sent an email earlier about the same problem in the 2.60.9 version. Checking the upper atmosphere weather report, I should be around -30 at this altitude. I have the download GRIB forcast checked. Using PMDG NGX if that helps anything.
