I fly CJ4 with the Working Title mod v.0.12.10, MSFS with latest World Update.

During two flights today I had complete engine failures, at somewhere over FL 210 suddenly a yellow error message appears on the MFD, and disappears so that I didn't know at first what happended. Maybe missed something on the checklist ?

So I switched to DEV-mode and used the new Record function. Made a new flight just in one direction and climbed. Start direct from runway so that the plane was configured to takeoff. 

And this happended:

Climb with FLC to FL 150: no problems.
Climb to FL 300, at FL 236:   Error Message on MFD:  NG HIGH

Then ITT climbs to Top: Error Message ITT

N1% drops, stall, crash... 

Has anyone else this problem ? The plane worked fine until today. What can it be ?

 

Thanks for any help!!

The weather is borked and your engine has had enough. Is my guess

Real weather glitch. Outside air temp is sensed at 250 degree Celsius in my CJ4

Monitor the air temperature, it will tell you the whole story 🙂

It's an issue with the live weather. Temperature at around FL260 spikes to insane temps, over 200 degrees. It's a back end, server issue. There are a couple of other threads talking about it.

Workaround for now is as soon as it hits you to switch to a weather preset, continue the flight, and switch back to live weather once you have descended past the FL that the issue appears.

Thanks for the explanation! So until this is fixed, I'll fly my BN Islander, that will NEVER reach that FL...  😁

First time I've encountered this after quite the number of flights in SU7 (all in westers Europe). Odd.
