Option to completely remove the GPS from the cockpit
-
Already there, and already auto-disables. Check the tablet options page for "Hide GNS 430". Enjoy!
@Black-Square I should never have doubted you! I clearly didn't look hard enough. Thank you!

Removing the GNS from the cockpit did not automatically disable using GNSS/WAAS as a position source, if that's what OP is referring to, however I assume that just removes the panel and leaves the GNSS LRU in the nose. Once I disabled it in Sensor Control it seems to stay off.

@jmarkows That's correct. The GPS that drives the FMS has nothing to do with the GNS 430, so it must be disabled separately.

@Black-Square Interesting! I thought it was the same thing. Can you speak more about the historicity of disabling that GPS with the 430 hidden? Like was it ever a factory option to have that the GPS that drives the FMS installed?

The LRN (an LRU... confusing, I know) in the nose drives the FMS for position information. The GNS is a completely separate unit that can only drive the CDI and GS. I'm not sure if the factory was adding the LRN by the early 90's, but all the airplanes have ended up with it today. For the most historically accurate experience, you would simply hide the GNS, and then disable GNSS as a source of position information on the CDU.

@Black-Square Interesting, thanks for the extra context! Should hiding the 430 and disabling GNSS also make the GPS RAIM page disappear in the CDU's System Control page?

@piedmonitor Disabling the LRN box from the Sensor Control screen just means the FMS won't use it, it's still in the aircraft and there's no way to take it out entirely.

The GNS has its own receiver, since its built for small aircraft. It's just a coaxial antenna wire that plugs in the back with an antenna mounted on the roof of the aircraft.
) or does it have its own receiver?
