Not without using external tools, because there’s not an exposed control mapping for it. However, if you weren’t averse to spending a little bit of money you could accomplish this fairly easily with Axis and Ohs. (There may be other tools that do something similar, but that’s the one that I know a lot of folks use for things like this. It’s a real control interface Swiss army knife).
You’d want to use it to bind joystick events of your choice to the AS1000_MFD_RANGE_INC and AS1000_MFD_RANGE_DEC sim events.
That’s an interesting thought. It would not be too hard to implement something like that using the existing systems. It would take a bit of work to make it configurable, but if you wanted to hard code it you could actually make that change pretty easily yourself by just changing two lines of code.
The configuration for how 3d object interactions are translated into the sim are visible to the user – they’re defined in XML files under ModelBehaviorDefs in the fs-base-aircraft-common package. For the G1000, you’d want to look at fs-base-aircraft-common/ModelBehaviorDefs/Asobo/GlassCockpit/AS1000.xml.
Lines 48 and 49 of that define what happens when the mouse wheel is scrolled on that knob:
<WHEEL_UP_CODE>(>H:#KEY_PREFIX#_RANGE_INC)</WHEEL_UP_CODE>
<WHEEL_DOWN_CODE>(>H:#KEY_PREFIX#_RANGE_DEC)</WHEEL_DOWN_CODE>
(Notice that those match up with the events I listed above for putting into Axis and Ohs).
These files are a mindboggling tangle of XML-based template logic and reverse Polish notation that sometimes leave you wishing you were reading the Necronomicon instead. But for our purposes, what you want to do could be done simply by swapping the wheel up and wheel down codes. Modify that file so that wheel up sends the range_dec event and wheel_down sends the range_inc event, and you should get what you want.
You’ll need to restart the sim for it to take effect. Also, if you have the G1000 mod installed, it overrides this file, so you’ll want to make the change there instead.
I need to go get my kid from school, but I’m happy to elucidate more on any of this for y’all later tonight if you want.
