Hello, i have an anoying problem: Everytime i click on the HDG Button to change the HDG Value, the aircraft starts ´´shaking´´ or juddering. If i´m in the VNAV and LNAV the curves a smooth!!! I hope you understand what i mean^^. What is the reason for this problem? Maybe a Bug? My System (it´s not really bad!!!)?Is there someone how can help me, please? Greetings from germany, maukro_1990
