@RuinedParsley22 Hi and thanks. I am going to try first what suggested by PZL104. If nothing happens I’ll try to use the open descent instead of the managed one. Do you suggest to use the open descent for the entire flight or only at approach where I encounter the problem? (Because with the managed mode I do not have any issue in take off - reaching cruise etc.).
I have asked PZ104 where and how to install this flybywire in case my problem persist.
