XP default Avionics Bus permanently on

[scotfleiger]

I have been trying to add the GTN 750/650 to the Islander and assign the correct power bus. Trying all the options I can only get the GTN 750/650 to switch on with the battery switch; unlike the radio/transponder and default GNS 530/430 with operate with the Avionics master switch.

I have found that the XP default avionics bus (sim/cockpit/electrical/avionics_on) is permanently on (=1) independent of the master battery switch. It is not controlled by the Islander switch (afm/islander/cmd/switches/avionics_Toggle). This differs from other XP aircraft like the Baron 58. I think it is a bug.

Yes, we need to override the avionics switch for proper behavior of a few other aspects of base X-Plane, this has the downside of the GTNs being tied to the main bus instead of avionics. We are looking at potential ways to get around this.
