@Flightmasta1 thanks a lot for the observations. The weak link is that although I have some good documentation, there are things that only a real pilot can see in the real plane, and your notes are very helpful.
One of the drawbacks are that Avanti is a side project that I'm working on when I have some spare time. Although I had some help from couple Avanti pilots, when I was working on the plane, they were not available, or their response was too late. So I had to come up with a few things, just from my experiences. For example, as soon as you get turn avionics on, there is an alignment procedure which I didn't knew which was and the duration, so I came up with one I remembered from one bird I flew. Which is wrong. A learn about the right one, just after released the last update.
Currently, I' very focused on pushing on the DC9. When I will have time to work again on Avanti, I will drop you a PM. Will be great, if you will be available, to get your help, to make thing right, one by one.
