Turning on the autopilot causes the plane to go haywire

[Rasseeeeee]

Hi,

I was departing out of Ibiza rwy 24 with the sid KARBE4E using the navigraph navdata. Shortly after takeoff i noticed the nav wasn't following the flightplan and put direct to the next waypoint. After that I pressed on the autopilot and the following sequence happended:

You can see turning on the autopilot causes the nose to go upwards like over 30 degrees.

I also managed to repeat the issue with the autosave file:

Had the same issue myself the other day.

Happens to me before I engage AP, but has on one occasion happened just after I engage the AP, similar to your video.

Something appears to be corrupted in your plan/autosave. 
I was able to reproduce the issue when loading your save but when I replanned the routing fresh from C&D there was no turn to the right or stall condition induced.  

Of note was the 430' alt constraint did not auto sequence to the next WP so we'll look into why that happens on certain procedures.

As for the altitude constraints, could that also be tied into my nav data issue mentioned here?

Possibly, but I'm going to work one problem at a time 🙂
