Could you report some examples of airport with RNAV (RNP) and RNAV (AR RNP) ? To see differences in charting, title notes and minima.
RNAV (RNP) implies AR.
To be more precise, in the context of PBN there are two types of approach specifications: RNP APCH, and RNP AR APCH.
1. RNP APCH. Generally charted as
RNAV (GPS) in the US or
RNAV (GNSS) internationally. This type of approach mainly consists of straight legs. Obstacle clearance and approach minimums do not require specific RNP capabilities. (Instead, minimums depend on approach type being flown, e.g., LPV, LNAV/VNAV, etc.) Example: KSFO RNAV (GPS) Z RWY 28R.
2. RNP AR APCH. Generally charted as
RNAV (RNP). This type of approach may include curved (RF) legs. Obstacle clearance and approach minimums developed against specific RNP capabilities (e.g., RNP 0.3 or RNP 0.1). Special authorization is required. Minimums not necessarily lower than RNP APCH (might even be higher). Example: KSFO RNAV (RNP) Y RWY 28R.
