Going back to the original question, an aircraft certified to RNP 1 only (say a G1000 without SBAS) would be able to fly a SID based on GNSS guidance, but would not be able to fly an approach, so going to an airfield it could fly the STAR using GNSS but would have to switch to another form of guidance for the approach. I found an overview of PBN codes related to Garmin equipment in Diamond aircraft here:
https://www.euroga.org/forums/mainte...quipment-codes Looking at this, any equipment with RNP APCH capability is also capable to use the 'lower' RNP categories. If you don't have the full PBN capabilities available in a specific aircraft, it would not keep you out of a certain piece of sky, but it would keep you off the specified procedures and force you to use other routes/approaches.
