practicable) during navigation via waypoints not published in the authorised aeronautical information.
       (7) The pilot in command of an aircraft must ensure that, for a terminal instrument flight procedure in which GNSS will be used as the sole means of navigation:
(a) the intended procedure is loaded from the navigation database by name; and
(b) waypoints are not added to, or deleted from, the procedure as so loaded; and
(c) the navigation system will fly the procedure as published in authorised aeronautical information.
Note   During the conduct of an IAP that is based on a ground-based navigation aid but where GNSS will be used for navigation, pilots should be aware that not all aircraft are capable of conducting reversal or holding procedures, or of navigating DME arcs. The pilot in command should confirm the aircraft navigation system is capable of conducting such operations.

14.03 Instrument approaches — QNH sources
       (1) Before passing the IAF, the pilot in command must set 1 of the following:
(a) the actual aerodrome QNH from 1 of the following (an approved source):
           (i) AAIS;
           (ii) ATC;
           (iii) ATIS;
           (iv) AWIS;
           (v) CA/GRS;
           (vi) WATIR;
(b) the forecast aerodrome QNH;
(c) the forecast area QNH.
       (2) The pilot in command must not use an actual aerodrome QNH for an instrument approach more than 15 minutes after receiving it.
       (3) If the forecast area QNH is used, the pilot in command must increase the minima for the instrument approach by 50 ft.

14.04 GNSS arrivals, and DME or GNSS arrivals
       (1) During a GNSS arrival, or a DME or GNSS arrival, the pilot in command must:
(a) use the destination VOR or NDB to provide the primary track guidance; and
Note   GNSS cannot be used to substitute for the VOR or NDB: see subsection 14.05 (1A).
(b) if there is a significant disparity between the track guidance provided by the destination VOR or NDB and the GNSS track indication — discontinue the arrival procedure.
       (2) For the purposes of paragraph (1) (b), a significant disparity is:
(a) for an NDB — a divergence of more than 6.9°; and
(b) for a VOR — a divergence of more than 5.2°.

14.05 Use of GNSS as substitute or alternative to ground-based navigation aids
       (1) This section applies to a ground-based navigation aid that is 1 of the following:
(a) VOR;
(b) DME;
(c) NDB;
(d) Outer Marker;
(e) Middle Marker.
       (1A) However, this section does not apply to the use of a VOR or NDB for a GNSS arrival, or a DME or GNSS arrival.
Note   Section 14.04 specifies requirements for the conduct of GNSS arrivals, and DME or GNSS arrivals. The relevant VOR or NDB must be used
