Hi Inibuilds,
I discovered that apu shut down in incorrect way.
How it is now:
N1 and temp just drop.
How is in real:
When You change the possition of the apu switch to off, system logic simulate overheat ,so you can see on the screen that temp is rising quickly to max possition and after reach upper position apu is shuting down.
Have a nice day,
