RNP AR 3-D 2.80 degree path to a DA of 4,621’ (300’ Height Above Touchtown).

VOR Rwy 02 5.31 degree path to an MDA of 4,950’ (629’ Height Above Touchdown) with a demanding 6 DME stepdown fixes from the FAF to the VOR, and with the following cautionary note:
the RNP AR has been fairly recent, and it takes you a bit west of the VOR final approach course through a valley where quite often a thunderstorm is happily doing it's thing, our airline had a CDA style procedure for the VOR flown in either FPA on the Airbus, or VS on the Boeing, scalloping was experienced but very slight, the visual sector of the approach was on a standard PAPI, never felt it was particularly demanding or otherwise...
