Implementing RNP APCH. Part A for RNP APCH – LNAV and/or RNP APCH – LNAV/VNAV operations and Part B for RNP APCH – LP and/or RNP APCH – LPV operations.
       4.2Positioning data from non-GNSS navigation sensors may be integrated with GNSS data if:
(a) the non-GNSS data does not cause position errors exceeding the TSE budget; or
(b) if paragraph (a) does not apply — there is a means to deselect the non‑GNSS inputs.

5 RNP APCH system functionality
       5.1 Subject to subclause 5.2 of this Appendix, the system must, as a minimum, meet the standards of functionality stated in ICAO Doc. 9613, Performance-based Navigation (PBN) Manual, Volume II, Part C, Chapter 5, Implementing RNP APCH. Part A for RNP APCH – LNAV and/or RNP APCH – LNAV/VNAV operations and Part B for RNP APCH – LP and/or RNP APCH – LPV operations.
Note   Guidance provided in AC 21-36, Global Navigation Satellite System (GNSS) Equipment: Airworthiness Guidelines, is also relevant.
       5.2 The requirement for the display of lateral position relative to the desired path is:
(a) a digital indication in 1/10th NM or less; or
(b) a relative indication which allows the pilot to determine deviation in proportion to a known indicator scale.
       5.3 Where the minimum flight crew is 2 pilots, there must be a means for the pilot not flying to accurately verify the desired path and the aircraft position relative to that path.
Note   To meet the intent of this requirement, in aircraft equipped with a single navigation system, both pilots must be able to access the system controls and view the system display(s) in accordance with the requirements of the applicable airworthiness standards.
       5.4Baro-VNAV authorised in accordance with Appendix 8 may be used in conjunction with RNP 0.3 under this Appendix.
       5.5Radius to Fix Path Terminators (RF Legs) authorised in accordance with Appendix 10 may be used in conjunction with RNP 0.3 under this Appendix.
       5.6If RF Legs are authorised for use in conjunction with RNP 0.3 under this Appendix, the aircraft must be equipped with a map display that depicts the computed aircraft flight path.

6 Operational standards – flight planning – general
       6.1 Before an RNP APCH operation commences, consideration must be given to matters that may affect the safety of the operation, including the following:
(a) whether the aircraft, and each member of the flight crew, has relevant authorisations for RNP APCH;
(b) whether the navigation database is current and appropriate for the region of operation and includes the navaids and waypoints required for the route;
       6.2 If the aircraft's essential RNP APCH equipment is functioning properly, the PBN capability of the aircraft must be indicated in the flight plan.
