I have a continuing problem with faster aircraft, particularly the jets going in an un-commanded bank several minutes after the AP is engaged, either in HDG or NAV mode. The plane will follow the HDG bug (with an un-coordinated indication from the slip/skid indicator) but it stays in a bank.  When I disengage the AP,  the plane levels out and will stay level,  but after I re-engage the AP, within a minute or so,  the banking re-occurs.  I have tried to adjust rudder or aileron trim but this just makes matters worse.

This problem existed on prior CH Yoke and Rudder Pedals as well as on the current  Honeycomb Alpha and Bravo and CH Rudder pedals.    Can someone suggest what is causing this annoying problem?  I have searched far and wide, and haven't found a fix.  Thank you.

Nothing new. Have you tried turning A/P off and back ton? Usually resolves the issue...

On my PC, that indicates that the yoke needs recalibrating.  MSFS is very sensitive to lateral control inputs while the AP is engaged.  Possibly increase the value of the null zone as well!

FF,  Yes. toggling the AP off and on again does level the plane for a minute or so.  As you watch,  the slip/skid ball slowly moves out of center, and then the plane banks without actually turning.

Bert, My yoke seemed well calibrated, but I did it again.   I also added some null zone.  Do you use an Alpha yoke?  If so,  what kind of sensitivity settings work well for you?   Thanks to you both.

Sounds like a rudder issue? Maybe check settings/bindings and/or remove your pedals etc.

I tried changing the null zones to 10, then 15.  I completely disabled the rudder bindings,  and disabled any keyboard bindings relating to rudder, aileron, trim, etc.  It made no different.  The Citation Jets  I'm working with continue to bank left about 10-15 degrees.  The plane does not turn left, but the  slip/skid ball is completely left of  the triangle pointer above,  suggesting the need for left rudder or less right aileron.  I don't have this issue with P3d or X-plane, nor with most of the slower planes in MSFS 2020 (Skyhawks,  Cirrus, etc. )  It does happen with the Baron B58 and all the airliners.  Stumped!

Sounds like might be worth submitting a bug report to zendesk

The thread title sounds like the start of a joke, so I figured I'd finish it off....

An aircraft goes into a bank with the autopilot engaged. The teller yells at it to get out, but the aeroplane continues on its heading toward the counter, then the aeroplane goes into a holding circuit, opens its cargo door, pulls out a gun, points it at the teller and demands all of the cash, yelling: 'It's time to pay the Piper!'

A week later, the teller is back at work when a Triplane comes into the bank and starts circling around suspiciously. The teller slides over to his colleague, points at the Triplane and tells her to keep an eye on it.

She asks why.

'Because I don't like the look of that Fokker.'

Chock, I needed the laugh!  Well done!!

 

I think the Cessna Citation Jets are a big part of the problem i'm having.  They are ridiculously unstable whether hand flying or on autopilot.   I found a long thread discussing the problem with these planes going back many months.  Hopefully a fix will occur soon.

The Working Title CJ4 mod helps a bit. Though it does not fix all the issues.

I never have the issue on WT CJ4, but I have it often with FBW a320. The plane will be in LNAV mode and all of a sudden the plane banks to the left or right. It just starts to orbit. The AP is still on. If I disengage and re-engage the AP it fixes itself for a few minutes, but usually it starts up again, perhaps at the next waypoint. Switching from LNAV to HDG mode kinda works. Cant remember if I got this issue on hdg mode before. I get it plenty on LNAV though.

I had that in the TBM a single time and it did not occur a second time yet. The banking was very low and it also lost altitude. Disengaging the ap shakes the plane around pretty violently and reengaging made it correct it elf and starting to bank after a shorty while again. 

Interestingly tis stopped as soon as I got over water. Looks like a rare bug with the wind over certain terrain. 

It's not just the Cessna Jets.  I flew the A320 Neo today, and it also falls into the left bank.  It straightened out with cycling the AP off and on, but the slip/skid indicator immediately begins to slide to out of coordinated flight, and the bank to the left returns.  I disconnected the yoke from the system and flew the A320 with the keyboard and Bravo Throttle.  Same story

I haven't flown for a while in the hopes that they would fix things like this. But, with my Honeycomb yoke and Saitek Multi-panel, the heading and altitude increments don't work properly. The yoke, stops working on and off, and, in the C172, the "death spiral" took the plane directly into the ground. Oh well, back to waiting for a fix.
