• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

FS2004 Nosewheel/Rudder to center/Taxi

Hey all...ya....long time! Need some help. Trying to create a hidden XML gauge that the slower you taxi the sharper it will let you turn, and the faster you go, the less it will let you turn, but also trying to get it so that once you release the rudder, it does not snap back to center. I am a complete noob when it comes to XML, so any help would be appreciated.

Doing this in XML will produce a conflict with the default nosewheel steering logic (controlled by the rudder axis) and produce ugly twitching of the nosewheel on the model.

This is some simple code used for simulating a castoring nosewheel. I wrote it for FSX, but I figure the variables should be good for FS9 as well.

(A:VELOCITY BODY X,feet per second) 0.001 >
(A:VELOCITY BODY X,feet per second) -0.001 < or
 (A:GROUND VELOCITY, knots) 40 < and
(A:SIM ON GROUND, Bool) and
if{ (A:VELOCITY BODY X,feet per second) 10 * 16383 * (>K:RUDDER_SET) }

Sideways velocity, induced by differential braking, is translated into rudder deflection and therefor nosewheel steering when on the ground and below 40 knots. Above 40, rudder control is released to provide aerodynamic control.
