the navigation accuracy associated with the route or procedure, for example, full scale deflection ±1 NM.
       7.8 Route centrelines must be maintained as close as practicable, as depicted by lateral deviation indicators or flight guidance, unless authorised to deviate by ATC or under emergency conditions. Navigation System Error + Flight Technical Error (lateral deviation) must not exceed the specified navigation accuracy.
       7.9 Brief deviations from the standard mentioned in subclause 7.8 of this Appendix are acceptable during and immediately after turns, but only to the minimal extent that accurate cross-track information may not be provided during the turn.
Note   Flight crew procedures and training should emphasise observance of turn anticipation commands and management of rate of turn.
       7.10 If ATC issues a heading assignment taking the aircraft off a route, the navigation system flight plan may only be modified when:
(a) ATC clearance is received to rejoin the route; or
(b) ATC confirms a new clearance.

8 Operating standards – flight procedures – RNAV SID requirements
       8.1 Before an eligible aircraft takes-off, the following RNAV SID requirements must be verified:
(a) that the aircraft's RNP system is available, is operating correctly and the correct aerodrome and runway data is loaded;
(b) that the correct runway and departure procedure (including any applicable en route transition) is entered in the navigation system flight plan and properly depicted;
       8.2 The operator must ensure that each member of the flight crew is aware of the functional limitations of relevant RNP systems and the correct application of manual tracking procedures for path following.
       8.3 RNAV guidance must be selected and available to provide flight guidance for lateral RNAV at no later than 153 m (or 500 ft) above the aerodrome field elevation.
Note   The altitude at which RNAV guidance begins on a given route may be higher, for example, "climb to 304 m (or 1 000 ft), then direct to X….".
       8.4 For an RNP 1 operation, an authorised method must be used to achieve an appropriate level of performance for RNP 1, for example, lateral deviation indicator, navigation map display, flight director or autopilot.
       8.5 The GNSS signal must be acquired before the take-off roll commences.
       8.6 For aircraft using (E)TSO-C129a equipment, the departure aerodrome must be loaded into the flight plan in order to achieve the appropriate navigation system monitoring and sensitivity.
       8.7 For aircraft using (E)TSO-C146a equipment, if the departure begins at a runway waypoint, then the departure aerodrome does not need to be in the flight plan to obtain appropriate monitoring and sensitivity.

9 Operating standards – flight procedures – RNAV STAR requirements
       9.1 The following must be checked and confirmed for RNAV STAR:
(a) that the aircraft navigation system is
