Switch OFF the ADF.

[Goofy]

Hello   

Avionics ON, regardless of the ON or OF position of the ADF switch OFF knob, it remains on (data remains displayed on the ADF). The corresponding dataref changes correctly: 0 or 1 for the ADF power_on.

The XP avionics_on dataref is permanently on for some internal Islander reason as Coop explained to me in an earlier post. It is powered whenever the battery master is selected on.

I'll take a look into this, I think right now the knob is not tied to power.
