OK… Great – someone that seem to know their stuff 
Question: Is it using the Asobo KAP140 AP, or a Carenado designed one, and if so, does it “turn on” correctly.
More specifically, if you are in a stable VS of 500ft/min climb, and you turn on the AP, does the plane keep climbing at VS 500 ft / min, or “JERK” down to 0 ft/min **
** or what ever the last VS was set for when the AP was last ON
