At flying over mach 1 , if you put the throttle to iddle the engines go to 80% thrust.
the Workaround with Putting throttle to round About 10 % works not more.
Now the engine stays at 80% till the Speed falls under M1.1 .
then the engines work normal.
(over M1.1 i can see the throttles are moving when i move my throttle. but engine stays at 80% ore more)
