See the following thread on the cause of this issue:

OAT of 248 C ?! (Impacts negatively on aircraft performance and autopilot function)

Doing a longer flight in the TBM 930 and went away from my PC for a bit during cruise and when I got back, I had bells ringing and watching the OAT, I understood why…have a look below [image] Didn’t see this bug before and now I guess I’ll have to descend to see if that will change the OAT to be a bit more realistic and allow the aircraft to perform a bit better than it does at this temp…
