Horizon 787 - Transponder setting

[C.Schaffhausen]

Hello, does anyone know how to program a switch to operate the transponder (STBY, ALT RPTG OFF, XPDR, TA, TARA)? Much appreciated.

You can use the lvar XMLVAR_Transponder_Mode with the following values:
    0 - ALT RPTG OFF
    1 - XPDR
    2 - TA ONLY
    3 - TA/RA
    4 - STBY

To assign to an lvar, you can either define your own preset, use a macro or add the lvar to an FSUIPC offset and use the offset controls to change the offset value and this update the lvar.

For example, to use a preset, add the following to your myevents.txt file:

//HorizonSim/787-9/Controls
Horizon_787_Trannsponder_Mode#$Param (>L:XMLVAR_Transponder_Mode)

and assign to that preset with a parameter of 4,0,1,2 or 3 for the various positions.
