5 RNP 2 system functionality
       5.1To meet the requirements of clause 3 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 2, Implementing RNP 2.
       5.2 An aircraft conducting RNP 2 operations in oceanic or remote airspace must be equipped with appropriate dual, independent, serviceable LRNS.
       5.3 An aircraft conducting RNP 2 operations in continental en route airspace must be equipped with at least an appropriate single GNSS RNAV system, provided that an alternative means of navigation is available if required for the class of operation.
       5.4FRT authorised in accordance with Appendix 11 may be used in conjunction with this Appendix.
       5.5If FRT are authorised for use in conjunction with this Appendix, the aircraft must be equipped with a map display depicting the computed flight path of the aircraft.

6 Operating standards – flight planning – general
       6.1Before an RNP 2 operation commences, consideration must be given to matters that may affect the safety of the operation, including the following:
(a) whether the aircraft and the flight crew have relevant authorisations for RNP 2;
(b) whether the aircraft can be operated in accordance with the RNP 2 requirements for:
 (i) the planned route, including the route to any alternate aerodromes; and
 (ii) minimum equipment requirements for the flight;
(c) whether, the navigation database is current and appropriate for the region of operation and includes the navaids and waypoints required for the route;
(d) whether operating restrictions, including time limits, apply to the operation.
       6.2If the aircraft's essential RNP 2 equipment is functioning properly, the PBN capability of the aircraft must be indicated in the flight plan.

7 Operating standards – flight procedures – general
       7.1 An RNP 2 operation must comply with the instructions and procedures of the OEM in relation to the performance requirements of RNP 2.
       7.2 At system initialisation, the following must occur:
(a) confirmation that the navigation database is current;
(b) verification of proper entry of the ATC-assigned route immediately after initial clearance from ATC to conduct the relevant RNAV route;
(c) action to ensure the waypoints sequence, depicted by the navigation system, matches the route depicted on the appropriate charts and the assigned route.
       7.3 The following checks and cross-checks must be made:
(a) a cross-check of the flight plan by comparing charts or other applicable resources with the navigation system flight plan and the aircraft map display (if applicable);
(b) if required, confirm the exclusion of specific navaids.
