I took a 737 on a hop from KATL to JFK today and listen to this...

I plugged in FL330 and clear weather with no wind.  Fuel was 40% in each wing and 50% in the center tank.
At about FL180, the aircraft started a small, but noticible "rocking" motion.  I rechecked the panel to see if fuel was accidentally transferring from tank to tank, but it was not.  Rate of climb was 2,500 fpm and as I climbed, the rocking became more severe.  By the time I reached FL330 the rocking was almost 10 degrees from side to side!

Any idea what that was all about?  Anyone ever experienced something similar?

Wasn't windy was it?  lol

Stingray686,

I've encountered a similar phenomenon with add-on aircraft where the plane will reach cruise altitude and begin "swimming" through the air like a dolphin.  My solution to this has been to substitute the .air file of another aircraft that works (perhaps a default aircraft) into the folder of the aircraft I'm trying to fly.  This has fixed the issue of level flight, but I haven't encountered your specific problem, so I don't know if it would help you or not.

A more pertinent question would be if you are using an add-on aircraft or not!?!
