@jmarkows Recent fix, was the version uploaded to Marketplace older maybe or are we talking about different things.
Should the expected behavior on an ILS approach using FMS navigation(with the optional Garmin not enabled or not being used) for an ILS approach, running under the assumption we have our nav radio tuned correctly that we've done everything else correctly and are on the correct course at the correct altitude be:
- Same as we are used to with most modern GPS based navigation systems, come in with navigation source set to GPS(again, FMS in this case but using general terms for insert relevent GPS navigation source), FD/Autopilot set to Nav, Approach mode armed and the GMS should automatically switch to radio navigation when the VOR is detected and automatically change over to first lateral and then vertical guidance from the ILS when the glideslope is captured. I did not do a perfect job of describing that process but close enough, basically exactly like in say a 737NG where you still need to configure a lot of things yourself, but assuming everything is configured properly the FMS handles the changeover from GPS to ILS navigation for you.
OR
- Do we at some point need to manually switch our source from FMS to Nav, probably using HDG to hold our approach heading during the changeover for good measure in case we have any hiccups, but if done at the right time with everything configured correctly we should immediately capture the VOR and be transferred back to Nav mode for at least lateral guidance if we are still outside of the glide slope.
Not sure if I did the best job of summarizing that, I think it makes enough sense for my question though.

#1, APPR should be an armed mode that grabs the localizer/gs once you pass through it. You shouldn't need to manually switch from the FMS as long as it will take you within capture distance of the ILS.
Was this a recent fix? Not at home to confirm what version was uploaded to Marketplace, but with the latest update being the one that I was under the impression was the one submitted you'd think it would be that one unless a little patch came out since.
I can't say with 100% certainty because there is a lot to be figuring out on your first couple flights with this aircraft, but on my first hack at an instrument approach I'm 90% sure I had everything set up properly, was definitely at the correct altitude and course and it just motored on by the glide slope at capture altitude and could see the ILS on the SDU. Since then I've just used the HDG hold while I manually switch sources and always successfully captured the localizer/gs. Totally possible I just had something set incorrectly on my second flight and first instrument approach using unique and complicated avionics.

@jmarkows I'll give it another go tonight, certainly a bit of a learning curve for the Starship avionics. Could've been user error on my first hack at an ILS approach that just gave me the impression it didn't automatically switch from FMS to radio, I at least now know that I know how to configure everything properly from successfully capturing from HDG mode
