That info should be on your aircraft Operations Specifications (OpSpecs); I also check it on the "Coded ICAO Flight Plan" part of our Operational Flight Plan; on the "PBN" section, it should say next to a bunch of other stuff, "T1", that means the aircraft is approved for "RNP AR APCH with RF (authorization required)". There are several codes for what kind of PBN operations the aircraft is approved, and that's a quick way to know.
Hope that helps.
