Can anyone help me with an annoying problem. when using fs2002 real weather, the default aircraft all show the corrcet temperature at say 33000 ft of approx -45C, but using any of the PSS aircraft, or more importantly the DF 737, it reports a far higher Temp of -20C or so. On changing back to a default aircraft it again show the correct Temp. This temperature difference is also noticible during the climb, and really affects performance. I am running FSUIPC 2.87.Any IdeasThank you

could it be possible, that the display in the df 737 shows

no, it's not a fahrenheit thing, as at ground level, the temperatures are the same in the learjet, and the df737

I think what you are seeing is TAT. I believe that stands for total air temperature (someone help me out here if I'm wrong). TAT decreases as speed increases, so in a jet flying at jet-like speeds TAT is lower that OAT (outside air temperature). I used to know the formula; it was posted on a forum by [email protected]. I don't know if Dennis S is still around these forums or not but if he is perhaps he'll post the fromula again. R-
