Hello, Tim.

I'm 110% with you.

My point is that: CDU is definitely not reliable in fixing T/D and flight levels. I have posted a few messages on the specific topic.

As so, I have to use the 'rule of three' which is very 'amateur' for this aircraft to make my descent but, after all, it works.

Although I have enough room for slowing down speed, it seems engines do not 'react' to throttle idle setting and keep stuck on about 300 knots.

As a 'final solution' I will remove and reinstall the add-on. I don't think it will work but.... who knows?  ;)

Best regards

Schmid
