Autopilot often missing points

[F1le]

OK guys I'm learning this plane, and I think it's awesome, worth each 1$ I spent on it. Did couple flights, still learning, most problems were able to fix by myself, but I still can't really manage the autopilot.

 

Very ofter my A/P NAV missing points and after passing one point it's just flying ahead without a turn. To fix it, I need to get into DIR mode and redirect it. What's wrong here?

Can you post some example screenshots showing PFD, MFD, and first legs page on the CDU, please?

I'll fly it tomorrow and will make screenshots when it happens. I can't even go out on couple minutes because I have no idea if in the upcoming point A/P will get lost of maybe after 5th point... Will do.

Do you happen to remember what the message was on the FMS?

This A/P for me doesn't work well, and I have no idea why some points it has problem to complete, at some points for example it's missing, it's flying ahead and 15nm before it it reacts and starts turning :

You have a lot of rudder input going in (see the slip indicator below the FMAs), most likely unintentionally, but at Mach .80 even a small amount of input has a big impact. You should recalibrate your Yaw axis, and if there's still an issue, configure a dead zone at the centre of it.

OK so I recalibrated Yaw axis (but it was fine) and added "dead-zone". Next flight tomorrow to test it. Let's see...

I've recalibrated every axis and also as you mentioned added dead-zone to Yaw ... and it looks like it fixed the problem. Weird because only CL650 had this problem. Toliss A319, Zibo 738 etc were flying all good...

Likely a difference in how their autopilots are implemented (using default, etc.).
