Hi! While it’s common to have rudder input directly connected to the nose
wheel on GA airplane, this is usually not the case on airliners. The FBW A32nx
implements a realistic hydraulic steering, but we had to use a hack so the
default rudder input do not interact with our hydraulic implementation (by
removing msfs rudder input from steering angle we are setting, which has
drawbacks) Is it possible to add a cfg possibility to disconnect steering from
rudder, so we are free from unwanted msfs nose steering input? This would help
a lot to avoid strange ground handling issues. Thanks!
For airliners I suggest reading this SDK section. The rudder will always be
active but for the steering you do want to reduce the amount based on speed.
So this way taxi has good steering but high speed on runway is reduced. The
SDK also now has an option to have no steering when stopped. [flight_model.cfg
- [CONTACT POINTS]
(flightsimulator.com)](flight_model.cfg - [CONTACT POINTS])
If this is something you are aware of and I am missing what your asking please
describe as you are using the aircraft in different situations like taxi and
faster speeds.
Tried anything possible but this do not meet our realism requirements sadly.
Our ultimate need would be to have no steering input from the sim and only
control steering angle throught STEERING_SET axis. Let me give some examples
that would not be possible with the solution you propose: -Steering of an A320
is limited to 20°/s speed -Steering can be turned when plane is stopped, but
only if actuators are available. -Steering speed slows with lower hydraulic
pressure -Steering from rudder is disabled when pushing the Rudder Disconnect
button on A320 plane. -Steering from rudder is disabled when plane is rolling
but hydraulics or any logic impacts its availability -… We are now
simulating everything correctly using the following hack: instead of sending a
steering angle demand back to msfs, we send steering_demand - rudder position
However there are drawbacks of small ghost inputs / issues with rudder assist
meesing everything… So even with our current solution this is not ideal.
Totally disabling msfs ability to steer the plane from rudder would solve all
of these issues, and let airliner developper achieve the needed realism, with
what I believe would not be a super hard feature to add. Thanks for the help!
Hello @Crocket The rudder input being added to steering is a problem we have
already identified and are tracking. We have something in our backlog but I
can’t tell when we will have resources to make progress on this. Regards,

Nice to hear it’s identified 
I guess the more “universal” solution woud be
to have the separate rudder and steering axis that could or not be linked by
msfs with configurable “mixing”. But the simplest solution to advanced
developpers that just send external steering input would just be to purely
disable this. Merci Sylvain!
@FlyingRaccoon Any further movement on this issue please ?

Hello @ModelMuncher
No progress on this.
This is in the backlog but it has not been prioritized yet.
