oscillating flight

If it were a real 146 I would suggest the c of g as being a few yards behind the tail cone.

Hi,
i notice a very slight but continous oscillating flight (like a dolphin), rather than steady flight with some random turbulence caused movements. Very similar to the F28's flight.
Is this as designed or did i change something to cause this?
@PZSW The oscillations are something we are aware of and are something we have been actively working on improving, but it is proving quite a difficult one to alleviate completely.
They were introduced with a previous MSFS Sim Update that included changes to the weather/atmosphere, so one setting in MSFS that can improve this is the Turbulence setting in Options > Assistance Options > User Experience > Turbulence. Try setting this to LOW or MEDIUM and that can reduce the likelihood of the oscillations starting.
If you do ever experience the oscillations again though, typically a gentle movement of the control column in the opposite direction to the pitching moment typically neutralises the oscillations. I appreciate that it's not an ideal solution, but that's what I've personally been doing while we work on a more permanent fix.

@Mark Thanks for the swift response!
I will check on the settings and if some combo is found that fixes it, i will let you know. One thing i did not mention but noticed before is that when activating “Turbulence” mode on the AP of the BAe146, the oscillation effect is reduced significantly.

From my experience, go into SYNC mode, follow the FD and trim out the plane. Once you are at a point where you only need minimal control inputs, the AP should be stable enough again once you disable SYNC.
It seems to be a runaway condition somewhere in the AP code that sometimes starts to overcorrect deviations and can't get back to stable without manual intervention, but once you've intervened it tends to remain stable for a long enough time again. Usually that happens on slowdown for descent/arrival/approach (somewhere below 220kt) and is easily corrected.
