In flight, when wind direction changes, even if the wind speed is moderate, or even if there's no change in the direction, but the high altitude wind is greater than 60 or 70 knots, my PMDG 747 X waves like a fishing boat during a storm and either the speed slows down (to mach 0.60 or less) , or goes up to mach 0.94 (!), and the plane becomes uncontrollable ! I've red somewhere, that my joystick might be the source of this problem, so I switch it off during the flights, but ther is no change !Does any one has an idea about this problem ? Thanks a lot.PS : I use the real weather of FS Pierre -LFRS-
