@aeronautorbust said in No option for G430 to be the primary GPS for most Blacksquare aircraft in the avionics selection.:
Is there a reason why the G430 STILL isn't an option to be used as the primary GPS?
Indeed, there is! As you might have noticed, both the TDS and PMS50 GTN 650's can also operate as the primary source of navigation when no primary GPS is selected. I asked Working Title to provide the same functionality a long time ago, and I was politely told that this would be too difficult. I then proceeded to modify their code to create my own solution for this, and I can confirm that it was very dirty, difficult, and inconsistent.
Just as recently as Flight Sim Expo this year (July), I spoke with a WT representative about this again, and referred to it as my most wanted feature. Perhaps the day will still come for this functionality, but in the meantime, we will both be patiently waiting.
