Autopilot rolling left to right all the time

John S.

Do you mean it rolls while trying to capture the new course? I’ve noticed a slight oscillation after a leg change, but I haven’t seen it constantly rolling. Could it be that you have some in-sim acceleration enabled?

@Dingle what are you talking about? I have not had this issue at all in either 2020 or 2024. (See my video in my Compleat Idiots Guide post)

Dingle

@dadgametime @John-S. No, no sim acceleration. It oscillates left right with a Periode of about 30sec (have to time it again and don't know exactly from the top of my head) with a heading change of +-3deg.

Also reinstalled everything, MSFS included without change.

I wish I could post a video here.

Dingle

@dadgametime Nice video,
Will watch it entirly sometime soon. You are only very briefly on a leg with your ND visible so it's hard to tell. I trust you if you say it doesn't happen to you though. Still does here.

@Dingle you have the 1/2 Bank on the AP enabled if above FL300?

Dingle

@x4569 no, mid 20k and no half bank.

Please upload it to YouTube, it will be a lot easier to help you that way

Dingle

@John-S I don't have a youtube account. Is there any other good way to share videos here?

John S.

you could totally go with one of the free video-sharing sites, this forum needs a bit of rep before you can upload files anyway. And even then the video might be a little too chunky to fit

Dingle

So noone has similar issues?

Dingle

@Black-Square @John-S. I have a video uploaded.

Any advice would be greatly appreciated.

Black Square

Thanks for the video. That's always immensely helpful. I suspect this is just a result of the rounding errors involved in OBS tracks that I have observed in many MSFS aircraft. Am I correct that the problem goes away when using AUTO-LEG mode?

Dingle

@Black-Square I will get right at it and try.

Dingle

@Black-Square Yes, you are correct. It seems auto leg is much more stable. It sometimes overshoots once or twice, but then stabilizes. Using OBS is causing my issues here.

Black Square

I've seen where it's about 75-100nm out where it starts to hunt for that course. I don't really know why this is, but I will keep my eye out for any hints that might lead me to a solution sometime soon.

Dingle

Yeah, that adds up, I also have the feeling that the legs must be far enough apart to cause it.

Thanks a lot

Correction: I also see it closer to a fix.
