Describe the bug
The TAT reading and SAT reading on the EICAS are showing the same value when they shouldn't as TAT=SAT+Ram Rise. Therefore TAT =/= SAT.

To Reproduce
Monitor the EICAS during a flight

Expected behavior
As mentioned above, TAT=/=SAT as TAT=SAT+Ram Rise.

Desktop (please complete the following information):

  • OS: Windows 10
  • X-Plane 11.40
  • Version 1.4.0rc2

Additional context
Here is a wiki page on ram rise: https://en.wikipedia.org/wiki/Total_air_temperature
On there is gives this really weird equation on deriving ram rise but there is just a scale that can be used to calculate it. Here's a video explaining it: https://www.youtube.com/watch?v=UMvuvLSMZEQ
