Maybe you could help me.
I do not know why but during my flight, established FL230 when weather data changes (X-Plane Weather used). The aircraft rises suddenly.
And when I try to recover FL with this very unstable aircraft, the engine shuts down. Perhaps because the speed increases abnormally during the maneuver.
It seems to me that when weather conditions change, in this case, it's hard to get away from the keyboard because the plane becomes totally uncontrollable
