Hi Martyn,
I want to apologize to the UFMC creator(s) about the negative comments I wrote before. I take that back.
I must recognize that I was operating the UFMC the wrong way.
After reading the manual properly, I reinstalled the UFMC and performed several test flights.
Now I can climb and descend using LNAV as well as VNAV, fly LNAV/VNAV and ILS (manual and automatic) approaches without any problems.
As the aircraft doesn't have Autothrottle, using the throttles properly on descent is not easy and requires training. But that is my problem. Not a UFMC problem.
I must learn and train a lot more, but everything I needed to complete a flight concerning the UFMC worked well!
... And I like the aircraft very much!
I used to fly a B463 long time ago. I don't remember it very precisely but I think the addon is pretty similar.
Best regards!
