solved Nose Wheel Steering

[sirtopper]

I have just noticed this behaviour in 1.0.4 so not sure if it was happening in older versions.

I have the rudders assigned to an axis and the tiller assigned to a separate axis.

If I use the tiller and apply max deflection I can then increase this further my deflecting the rudder pedals at the same time. If you look at the tiller handle it moves past the marks and also the nose wheel moves past the 90 degree deflection.

Not sure if this the correct behaviour?

Many Thanks for the continued updates.

Hi Tony,

we don´t really support separate inputs for tiller and rudders - because they are pretty rare and X-Plane does not really allow it well. The way this works in the real plane (tiller overriding rudder pedal input) is not emulated, so expect to see some weird behaviour when using both at the same time...

Cheers, Jan

Hi Guys,

I played around with a LUA script and I'm now able to use my tiller and rudder independently. There is however no "override" between the two.

So rudder axis will only move rudder and tiller axis will only move tiller... 

Just out of curiosity... how does it work in the real plane?

Thanks

[Litjan]

Hi Jean,

glad you got that working!

In the real plane, the tiller will override the rudder - so if you hold the tiller, the nosewheel will not turn with the rudder. But if you move the rudder, the tiller moves with the wheels.

The rudders won´t move if you use the tiller, though.

Thanks for the info Jan.

I would then imagine that at some point (speed) the tiller should not respond to rudder input anymore?

[Litjan]

No, the tiller will always respond - but you are not supposed to use it at higher speeds, it is too sensitive. During takeoff and landing you should only use the rudder (over about 30 kts).

Thanks Jan. Makes sense.

I've subsequently changed my LUA script to only allow a max of 7 degrees nose wheel steering when using the rudders. The tiller will give me 78 degrees.

Works a charm.

Now I'm just looking for that dataref which knows whether I'm holding the tiller...

Care to share the LUA script Jean?

Cheers,

Hi André,

I'm still tweaking the script and will share once I'm happy that it will be usable,,,

Cool jfjoubert, looking for it also

Hi sorry to open such an old topic,

I just purchased the IXEG 737 and I have assigned the rudder yaw to my rudder pedals. either with or without assigning a separate axis to the tiller, the nosewheel won't move.

Check whether you can use the rudder pedals on any of the default planes in X-Plane... if not then your rudder pedals are not properly mapped.

[PilotNL]

The rudder pedals work fine, the rudder works fine too on the IXEG737. it is only the nose wheel that is not working.

[jfjoubert]

That's strange... you don't perhaps have any FluWithLUA scripts which might interfere with the nosewheel steering? 

[PilotNL]

Ok I have deleted all  files in output/resources and then re-assigned all axis and keys. now it works

[jfjoubert]

Glad to hear you got it working again.

[PilotNL]

Hey, and it happened again!

I have narrowed the problem down a bit, it happened after pushback. I will do some more testing tonight to find the source of the bug.

[Litjan]

Interesting, I am following this to see if you find out the exact problem... you are not depressurizing the A-Hydraulics for the push, are you? (Some old procedures ask for this, when you don´t have a steering bypass pin). In this case make sure that you switch them on again after pushback...

Jan

 

[Redglyph]

I have the same problem. Hydraulics are on, were not depressurized.

It worked the first time, but not anymore, I see the rudder pedals moving normally but the nosewheel is not effective.

IXEG v1.2, XPlane v11.05r2 (build 110501 64-bit)

 

I've also noticed the tiller had a tendency to twitch all the time when parked on the ground, my pedal calibration is fine though. The first time, when I could use it to steer, it wasn't twitching during the taxi.

Are you using any other plugins (pushback, etc.)?

Make sure that the default X-Plane failures are disabled, maybe your nosewheel steering "failed".

Display the raw deflection data for nosewheel steering to help you see whats going on.

It is possible to assign the tiller to an unused joystick axis, this may even happen by default. Check that this is not the case, it is a separate axis from "nosewheel steering".

Let me know how it goes, Jan

Hi,

I had same type of issue : in XP you can assign a button/key to something like 'nose wheel steering on/off'. I don't remember the exact name as i'm not in front of xp11 now.

This action was automatically set to a button of my joystick.

Maybe you should check all your buttons/keys assignments :-)

 

 

[Redglyph]

Thanks for your replies!

That's strange, I do have a button assigned to wheel steering toggle on/off (probably the default for this joystick?). The first time I ran the IXEG 737 I didn't have to use it, now it seems that I have to toggle it before taxiing. I suppose it's as good a work-around as any.

I would try to unassign that button and then run again. There are thousands of people running the IXEG 737 and they don´t need to toggle the nosegear to taxi with it...so chances are you can get those results, too .

Cheers, Jan

I'll try. But that could actually be desirable to keep that button for cross-wind landings.

Errr, no (at least not for the 737 )!
