Rudder Issues with Airliners

rschmidt1960 · January 23, 2018 at 5:31 AM

I'm having a strange issue. At full stop, several models (747, A320, 737 and Q400) all skew the rudder to the right when the pedals are centered. At speed, it appears to return to normal, but taxiing is all but impossible. All other aircraft, including the lear, are just fine. I'll keep working the issue and see if I can find any other clues. This is a recent problem.

My rig is an I-5 7500 (3.4 ghz), 16 gb ram, Geforce 1060 (6gb ram), Thrustmaster Cougar Stick and Throttle, Thrustmaster rudder pedals.

Thanks for any insight - Ray Schmidt

Hi,

I think that is an issue with the yaw damper, it needs to behave differently on the ground and not try to match the turn rate to the bank angle. Due to the sloped terrain the aircraft isn't taxiing with wings level, you have a slight bank angle. And this bank angle causes the rudder be deflected which of course shouldn't happen.

That's really interesting. I can't imagine the variables involved in an application like this.

Oh yes. And believe me the number of variables is only growing larger

In more testing, I should be exact in the description. when at rest, the nose gear on these airliners are fully deflected to the right. Full left pedal produces an effect just left of center. This only appears on the aircraft I've described. The lear, and all of the smaller aircraft perform normally. I've tried to disable the yaw damper, but that doesn't seem to have an effect. I have an older set of rudder pedals that I think I will try next to see if I can localize the problem to the hardware - but that wouldn't really explain why I only see the effect in certain models. I actually like troubleshooting, so I'll keep you posted if I can find more commonalities.

One more observation; the pedal position on the screen match the rudder position of the physical pedals. The tiller position matches the position of the nosewheel.

I had the same issue. Here's how I fixed it.

1. Go to Settings

2. Go to Controls

3. Under the Primary section, scroll all the way to the bottom and you will find an entry called "Steering Tiller"

4. Note which controls or buttons are assigned to this function.

5. Go back into the game and use those controls or buttons to steer your airliner on the ground

In my case, I assigned a specific lever on my CH Throttle to act as the steering tiller control.

Hope this helps.

Regards

Makes sense - I didn't see those assignments before. I'll give it a try. Thanks for the help.

Hi Kenneth -

Well, you were right that the issue is an unassigned tiller control in the settings menu - thanks for the tip. I wound up assigning my rudders to both the tiller and the rudder controls and they are now coordinated. I do love this program!

Glad to be of assistance Ray.

That's one of the great values of this forum.
