Remembering back when I used to fly the FSL Bus, in order to steer with the tiller, I had to press the PEDAL DISC button. As long as that button was pressed, I could steer the bus. That button would automatically depress on TO after a certain speed.

The Fenix logic seams to be inverted somehow on my end. If I press the PEDAL DISC button, I'm unable to steer and also the tiller would not turn. Having the button depressed, the tiller is turning and steering works. I'm wondering if there is a config issue on my end.

I have an AXIS assigned for tiller and another for Rudder (IIRC).

I don't remember the FSL bus (flew it way back in FSX, but never in P3D), but this sounds like it may be a sim-only "tiller emulation" feature for users who don't have a separate tiller axis.

On the real aircraft, "PEDAL DISC" is a momentary button (meaning that it reverts back to the "up" position once you release pressure on it). Its purpose is to disconnect the rudder pedals from the nosewheel steering so that you can do a rudder control check during taxi without causing the aircraft to change direction. "PEDAL DISC" does not have any influence on the behavior of the tiller.

So in summary, the behavior should be:

• Rudder pedals: When "PEDAL DISC" is pressed, rudder pedals control only the rudder. When "PEDAL DISC" is released, rudder pedals control the rudder as well as the nosewheel steering (with limited deflection).
• Tiller: The tiller always controls the nosewheel steering, regardless of whether "PEDAL DISC" is pressed or not.

The Fenix does have some specific functionality for users who don't have a separate tiller axis:

This is controlled by the rudder pull tab. Maybe this is causing the behavior you're seeing?

I can't currently verify what the behavior of the Fenix is, but the description above does sound as if they have modelled it correctly.

Not sure if it’s helpful, but:

If you have a combined tiller/rudder axis: You have the option to use a new hidden clickspot - the rudder pull tab - to lock out the rudder while taxiing and use the tiller. This will automatically disengage when you are on your takeoff roll and your speed exceeds 45 kts w/ Thrust Levers in FLX or TOGA.

Where is this click spot hidden?

So, basically, it should be pressed after line up before takeoff thrust set? I'm not sure how to use this clickspot...

Do you HAVE a separate tiller axis or a combined tiller/rudder axis?

Combined...

I press it after I’ve done the flight controls checks, before taxi.

Then you can use the clickspot (if you want to use your rudder axis as tiller). You could also not press it and just use rudders for taxi, even though that’s not realistic.

If you have separate axis for rudder and tiller, the Fenix has the correct behavior. It took them quite long to get it back to work, but in the end, it's correct now.

I'm having terrible trouble trying to activate nosewheel steering in the current/latest Fenix A320 and my Logitech X56  + rudder pedals.

I've tried every combination of rudder+tiller disconnects - with and without mapping the tiller to the rudder axis. The tiller never moves (and there's no corresponding cockpit animation either).

No problem with other airliners (FBW A320 etc.).

I've Googled it to death (including the latest Fenix help) - and tried all the voodoo. I'm all out of ideas.

All suggestions welcome!

Update/correction:

I have the Thrustmaster Warthog HOTAS - not the X56 (!!).

I managed to get it to work by assigning the steering tiller axis via FSUIPC, but I'm wondering why I should *need* to do that ...

You don't.

Just set a rudder axis per normal in MSFS and click the rudder pull tab when you want to use nosewheel steering. You don't need to deactivate it either when lining up, it will automatically do so when you apply takeoff thrust.

This is not how it works IRL - that is just how it works on that product.

This is correct
