Hi,since the new upgrade,whenever you turn on the auto pilot in solo,if the alt and vs are on,the plane starts pitching like a ship hitting the waves,starting slowly to more violent up and down move until that it disengage the A/P. I mostly tryed it on B747 s,but I am asking that what Devs are doing about this problem.(note that if you turn off the VS,the problem stops)
This is the level flight and then a few sec s later==>
From the Hud view:
At high movements,It stops a sec and banks a little,and continues
