Hmm … I played with weather switching … and there seems to be one more effect.
Barometric air pressure (=altitude)
So when I switch from “Clear skies” to “Live (really bad) weather” the aircrafts altitude jumps dramatically … and if I am on “autopilot” the aircraft responds with a rapid adjustment of the flight path.
If I disable the autopilot before I switch the weather I still can see the aircraft taking some kind of “hard hit” (like if the instantaneous change in lateral wind speed induces some impulse that causes a pendulum reaction) … but at least the aircraft does not simultaneously apply “radical” course corrections.
Just wondering … maybe some part of the failure code looks at (rapid) altitude changes and converts them into G-forces … and they then “break up” the aircraft?
