High temperatures using xEnviro

[chamiltoc]

Hi there, great product. This aircraft is what had me purchase X-Plane after years and years of P3d. 

 

Anyway, my current issue is this. I was using the 650 with no issues, then purchased xEnviro. On my first takeoff after install, I found I could not rotate the aircraft and would not accelerate past 120kts. I then found that the OAT was reading near 60 degrees Celsius (from the PFD.) I reinstalled the 650, xEnviro and even x-plane however the issue still persists. 

 

I reached out to xEnviro with the issue, they stated they had not seen anything like this and it looked like it could be the plugins for the 650 incorrectly extrapolating their injected METAR weather?

 

Here is a screenshot showing the active plugins. I have tried disabling OpenWXR (which shouldn't affect it), OpenGPWS and really all of them however the same issue persists.

Any ideas? Much appreciated!

Hello, 

Can you try flying the default 172 under the same conditions and report back to us? 

Many thanks

Here I have started a flight from KDLH Duluth, where the temperature should be negative 7c. The temperature is less pronounced here but still significantly higher in the 650. Here is a screenshot of the Challenger, and then the default 172 at the same location.

 

Let me know what you think.

 

Thanks again

Added observations, the temperature seems normal until the takeoff roll in which the temperature starts to increase dramatically. Here is the log and current temperatures.

The reason the displayed temperature is increasing rapidly right before takeoff is that the probe heat was turned on while on the ground. The probe that measures SAT is heated; until you start flying, the temperature is shown artificially high as a result of a hot probe. 
 

I’m guessing if you had an issue getting airborne in Duluth, MN it may have been related to ice built up on the wing surfaces overnight.
