RNP APCH is synonymous with RNAV(GPS)/ RNAV (GNSS)/RNAV (RNP)

With RNP APCH:
Initial and Intermediate segments RNP 1.0
RNP level down to 0.3 for Final Approach segment only.
You can have 1 turn prior to the FAF.
Missed approach not less than RNP 1.0

REQUIRED RNP APCH EQUIPMENT
The minimum equipment required to perform RNP APCH operations is:
One FMS
One GPS
One MCDU
One FD
One ND on the PF side
Two FCU channels
One PFD

I have always been amused with the missed approach RNP 1.0 min, as when going missed, it all falls apart from 0.3 to 1.0 (from the MAP!) This requirement really restricts procedures, as commonly, the tower is the controlling obstacle.

In the U.S. I can fly either of these two approaches with the most basic of RNAV IFR approach-capable navigators, such as a Garmin 400. I don't need a FD, or auto-pilot, or FMS, or dual displays, etc. Just a basic IFR panel and a basic CDI that displays the RNAV course. To fly to LPV minimums the example basic navigator would have to be a Garmin 430W. The note "RNP Apch" replaced the other note I have highlighted at Reedley.
