Nosewheel Shimmy - 747-400F

Recommended Posts

I've done a search, but have found no real answer to my problem. I can't get the nosewheel of the 747 to track freely after touchdown and rollout. While on the ILS approach, I've disengaged the FD prior to touchdown, and disconnected the AP while on rollout. Even so, the nosewheel is very sensitive in taxi and I have to fight to keep the aircraft centered on the taxi line. Any idea what I might be doing wrong and how to correct this. Help is appreciated!!! Thanks. BTW, this is in FS9.

I had the same problem. After an autoland, I would disconnect the autopilot and the aircraft was very difficult to control while taxing. I discovered that you need to center your aileron and/or rudder trim. This autopilot is using trim to maintain centerline on the rollout. This fixed the problem for me. Hope this helps.Dustin

No the rudder trim which is on the center pedestal panel. In FS go to your control assignments menu. Under "control surface commands" find "rudder&aileron (center)". Mine is set to Num5 (can't remember if this is default or not). Next time you land and disconnect the autopilot on the rollout, hit the button or key assinged for "rudder&aileron center" after the autopilot is off. This should solved the control problem for me.Dustin
