Hey all. So all of a sudden I'm getting a rocking back and forth motion whenever I'm in flight. Happens with any aircraft, fleet or default. I thought it may just be the weather so I cleared that and still same issue. I also checked the settings on my joystick and nothing. Any ideas? It's very subtle but noticeable.

left and right or up and down. You may want to check that your Yaw Damper is on

OK, happens to me sometimes too. Slight motion, not alot, but consistant.
Here's the funny thing. I noticed the same motion in an ERJ from El Passo to DFW. I asked the flight attendant about it, she said, "We're not oscillating." But you could watch my shadow on the seat in front of me and clearly see that we were.
Now in tune to this, I noticed the same thing on the 737 from DFW to ATL.
Hmmmmmm . . .

I encountered this in the CRJ when you were close to stall speed. For some unknown reason the autopilot would not maintain enough engine RPM to keep the airspeed up. Once the plane started slowing down with the nose at a high pitch angle, the rocking began. Even when I manually throttled up, the rocking continued, although not as harsh.
Just something to note.

Are you talking about real world experience or simulator?

Actually, no. Those were RW experiences.
A slight roll oscilation throughout cruise.
EDIT: You were talking about the CRJ near stall speed . . . opps.

Well it was happening to me in the fleet A320 (during my check ride no less). It seems like it must have been a bug or something, because once I rest my computer and loaded a new flight it stopped.
