Phenom up/down motion at cruise


Recommended Posts

Hello All,


 


I was wondering if anybody knows a fix for the up/down action when at cruise ALT (FL370)? At normal speed everything seems to be fine, but when I speed up FSX to 8/16 x the speed, it starts up/down motion. 


 


I'm guessing that maybe what i'm seeing is the slight adjustments that are always being made by the auto pilot. When in normal time you wont really notice the minute changes that are being made to keep the heading and altitude, but speeded up they will appear magnified.


 


Is there a fix or something I can change for the autopilot to keep everything straight? All input is greatly appreciated....... 


 


Cheers,


 


Jason

It's pretty common to see this in many add-ons.  I think what's happening is that the motion of the plane is being sped up 8x, but the autopilot is basically still working at 1x.  Therefore, it's sort of working against itself and it causes some exaggerated corrections.  Another example of this can be seen when you have a significant turn in your route while running at 4x or greater: the AP NAV will usually overshoot the turn and end up making a series of S-turns back.
