Autopilot altitude knob LVAR

Featured Replies

I'd really like to be able to control the selected autopilot altitude using my external hardware. I'm having trouble identifying the LVAR for this knob and just wondering if anyone knows what it is please?

Not really. I used it a long time ago. Is that the only way? (I use FSUIPC and have created macros for it)

I use LINDA to discover the LVARs, then write my macros and Lua scripts for FSUIPC.

I think FSUIPC has a way to log all the LVARs but I prefer LINDA visual method.

Yes, I've used FSUIPC log to find the LVARS but I can't work out which LVAR it might be for the Altitude selector. The only one I found that might be possible is CUSTOM_AP_ALT_VAR_SET but I can't make it work. I was hoping someone may have found the correct LVAR to use how to program it.

Try:

L:H850XPAltInnerWheelUP, number

and

L:H850XPAltInnerWheelDN, number
