No contrails at 37,000

[Bobsk8 12,732]

I always had contrails in P3D at altitude. Today I am flying the NGX at 37000 and have no contrails at all. Temperature is -29C.  What could be wrong?

Isn't -29C at FL370 pretty warm? I always figured a normal temperature is around -50C.

Hi Bob,

 

From the manual:

 

Contrails 

[...] With 737 Immersion, contrails are visible even at low altitude when the air is saturated and the temperature goes below -25*C (-13*F) or lower. Denser contrails can be observed at -35*C (-31*F) or lower. [...]

 

 

Make sure you are looking at the OAT and not the TAT.

 

Regards,

Keven

OK, this is December in New York City, but I forgot they are having a heat wave up there as well as in Atlanta where I live. Thanks, and I was looking at the wrong temp.

Found the problem. I forgot to run VFX Central in admin mode... I should know better....

VFXCentral always runs in admin mode... but... oh well, if that fixes your contrails it's cool!
