The problem is caused by the Yaw Damper. Turning it OFF will fix it. It seems that PMDG has mixed up the ON and OFF position of the switch.

Thx for the info, which may confirm my hypothesis above - dutch roll...

I didn't think it was possible to turn off the YD in the 737, without it turning off the autopilot?

--------------------------------------

I have seen this wobble before and I swear it was 100% related to Asobo's rather problematic turbulance modes.

I set turbulance to LOW in MSFS and I've never seen the wobble problems since.

I'd suggest turning turbulance to low in MSFS settings. If it removes the wobble - great.  I then bought Realturb which is only £11 (also a free demo to test it out).  It gave me fantastic, realistic turbulance effects. You can also set up different levels and types of turbulance on a per aircraft basis.   

Best £11 I've spent in a long time.   In my experience, MSFS's own turbulance is very poor and unrealistic, on all settings but low.

It's dutch roll... 

I don't know what you mean. Turning off the Yaw Damper on the 737 does not turn off the Autopilot on the 737NG. They are independent systems.

I have set MSFS turbulence to "Realistic" and I have completed four flights now - and on all of them, the "wobble" (aka Dutch Roll) disappears when turning OFF the Yaw Damper.

No disrespect but whatever you want to call this artifact is irrelevant.

You should never see dutch roll in a B737 with a working Yaw Damper.

My point was for him to disable (or set to LOW) MSFS turbulance settings completely.  This worked for me and I had the exact same wobbling.   I then found I missed some depiction of turbulance, so bought Realturb which is completely independent of MSFS's own turbulance effects.  Meaning you can turn off the latter and get rid of all of it's artifacts.

Personally, this is a very unrealistic 'solution'. 737s do not fly with their Yaw Damper turned off.

It is MSFS's problematic turbulance depiction that is interacting with that Yaw Damper.  What is most realistic to turn off.... a broken turbulance depiction, or an airliner's Yaw Damper system? 🙂

Because it points to Holger's posts regarding a possible bug with the YD logic in the addon...

I don't own it and will only be able to test when the -700 gets ported to 2024, but as other users say, other airliners don't suffer from it...

Which I read, as it was just above my comments (and it was his comment that I was responding to!)

IMHO; many people have seen the wobble artifact, both with PMDG and other aircraft.  If turning off the YD "fixes" it then that merely points to an issue with turbulance, as that is what the YD is responding to.

Turning off an essential control system in a passenger aircraft is very unrealistic and too much of a compromise in my view - and I honestly don't think it's necessary.   But I've already mentioned this in my post above.

I strongly agree that there has been a known problem with ASOBO implementation in the core function since day one, in how they modeled this turbulence, regardless of the new settings implemented in the menu. Also, we need to understand that ASOBO, in their SDK, introduced specific adjustments to the AERODYNAMICS section, where certain developers recognized and took advantage of this fine-tuning of the airlow, creating a very plausible reaction. 

Unfortunately, PMDG, as usual, likes to put the blame on anybody else (this has been going on since day one), on any tool out there, on any other interface that is enhancing this MSFS2024, but not on their inability to create good programming code. They refuse to see what others managed to achieve without having these issues like this wobbling, more so of this "dutch roll" as rightfully mentioned by  @jcomm or this FD, LNAV, AP issue. They need to snap out of this mentality and take notice of other developers out there who don't blame anyone else and just do it. 

Now, as it was mentioned here, that it might be a possibility with the switch in the wrong position-functionality, either way, we should have an indication on the upper panel, or EICAS message (I don't remember if it shows on EICAS), so for the current and qualified pilots, please correct me. 

Despite this little bug in the logic of the YD switch position, I like this bird. Today, I have flown Salzburg - Amsterdam - Hamburg - Bergen - Hamburg and I had a great time. However, I am already looking forward to fly the Fenix A32X during the next days as it feels "more complete".

A message is shown when deactivating the Yaw Damper. We just need to ignore this message and click it away. The message is correctly linked to the position of the switch, but the logic of this switch seems to be reversed.

I wish iFly launches their version of the NG. I'll never touch PMDG one again if they keep ignoring their flight model and the sim physics. Seems they don't want to put the hours to correct this, maybe they will loose a lot of money paying staff for correcting all these flaws. That's a good reason to ignore us, for them, not for ones that would like a good representation of the NG. I think I'll switch to the iFly max, tired of making unrealistic pitch and flare to correct for the a badly modeled ground effect.
