Autopilot altitude oscillations

[Jamie]

One of my most favorite planes to fly is the Falcon 900B V3  and the panel is fantastic , but I seem to get constant porpoising ( 20 - 80 ft. ) with the autopilot engaged and an altitude selected .  

Just wonder if anybody else has had the same experience and wonder if there is a fix ?   I do not have that problem with the  default 737 400 .
FS2002 --  Windows XP .

Thanks ,

Check to see if it comes with a yaw damper and turn it on.

Hi Garymbuska ,

I do not find a yaw damper . I just now flew at 3,200 ft. and 250 knots and was pretty stable .  Perhaps speed has an affect ??    Nobody else has commented on having the same problem so may just  me or my PC

Thanks ,

I have a similar problem, namely when the autopilot is engaged the aircraft will sometimes oscillate in pitch mode only.

Hi ,

I placed this Post and am in the midst of flying the Falcon 900 Vinair on an IFR flight from Amarillo , Texas to FT. Worth Meacham with Real World Weather .  I set my cruising altitude at 22,000 ft. and the Autopilot has held it exactly with no oscillations whatsoever .  

Must be my PC causing oscillations occasionally ?? !!!

If any of you have not flown this plane and this fantastic panel , you are missing a treat .  This is my favorite panel and you can actually see over it for landing .  Easy to set radios , great autopilot , and is large enough to read altimeter barometric pressure settings , etc .  Has everything you would want and has the GPS Icon and switch placed together as they should be .  Just superb in my opinion .

If only it had the gorgeous virtual cabin of the Falcon 50 !!!!
