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.

7 Operating standards – flight procedures – general
       7.1 An operator must ensure that flight procedures described in this clause are complied with.
       7.2 The following must be checked and confirmed:
(a) the waypoint sequence;
(b) the reasonableness of the tracks and distances;
(c) the VPA if using RNP APCH-LNAV/VNAV;
(d) that the GNSS sensor is used for position computation;
(e) if barometric aiding is used — that the current aerodrome barometric altimeter setting is entered.
       7.3 The operator must ensure that the appropriate displays are selected to permit monitoring of the aircraft's:
(a) approach path; and
(b) position relative to the approach path (cross-track and, where applicable, vertical deviation).
       7.4 The aircraft is to be established on the final approach course no later than the FAF.
       7.5 Descent in the final segment is not to be commenced unless:
(a) the appropriate approach mode is annunciated, namely, LNAV, LNAV/VNAV, LP or LPV; and
(b) RNP 0.3 is selected and available.
       7.6 A missed approach procedure must be conducted if:
(a) the navigation system display is flagged invalid; or
(b) there is a loss of integrity alert; or
(c) the integrity alerting function is not available before passing the FAF; or
(d) during a segment of a procedure, Cross-track Error/Deviation equals or is reasonably likely to equal the RNP for the segment of the procedure; or
(e) where NSE is available during a segment of a procedure, including NSE measured as Estimate of Position Uncertainty, NSE + FTE during the segment equals or exceeds the RNP specified for the segment; or
(f) if the aircraft is equipped with serviceable automated cross-track error alerting — when a Cross-Track Error/Deviation alert is received.
Note 1   NSE and FTE are the largest tracking errors for RNP APCH. ICAO Doc 9613, Performance-based Navigation (PBN) Manual, notes "cross-track error/deviation" as a component of FTE.
Note 2   ICAO Doc 9613, Performance-based Navigation (PBN) Manual, Volume II, Part C, Chapter 5 – Section A, provides guidance on the use of RNP APCH procedures. Pilots are advised to track along procedure centre lines unless authorised to deviate by ATC or under emergency conditions.  So far as practicable, the cross-track error/deviation for normal operations should be limited to 0.5 NM (½ x RNP) for the initial segment, the intermediate segment and a missed approach, and to 0.15 NM (½ x RNP) for the final approach segment. Brief deviations are acceptable during and immediately after turns where accurate cross-track information is not provided during
