determine the aircraft position relative to, or its distance from, a VOR, NDB, DME fix, a named fix defined by a VOR/DME location, VOR radial, or NDB bearing; and
(b) navigate to or from a VOR or NDB; and
(c) hold over a VOR, NDB or DME fix.
Note   The operational uses of GNSS described in this clause apply even when a navigation aid is identified as required on a procedure.

5 Use of suitable GNSS-based area navigation systems not permitted
       An otherwise suitable GNSS-based area navigation system is not permitted to be used for:
(a) NOTAMed procedures. Unless otherwise specified, navigation on procedures that are identified as not authorised without exception by a NOTAM. For example, an operator may not use a suitable GNSS‑based area navigation system to navigate on a procedure that is based on a recently decommissioned navigation aid;
(b) Lateral navigation on LOC-based courses. Lateral navigation on LOC-based courses (including LOC back-course guidance) without reference to raw LOC data.

6 Operating requirements
       General operating requirements
       6.1.1Pilots must comply with the AFM, AFMS, operating manual, QRH or pilot's guide when operating the aircraft navigation system.
       6.1.2Pilots may not use the GNSS-based area navigation system as a substitute or alternate means of navigation if the aircraft has an AFM or AFMS with a limitation to monitor the underlying navigation aids for the associated operation.
       6.1.3Pilots of aircraft with an AFM limitation that requires the aircraft to have other equipment appropriate to the route being flown may only use the area navigation system as a substitute means of navigation for out‑of‑service navigation aids, but not for inoperative or not installed equipment.
       Navigation database requirements
       6.2.1Pilots must ensure that the installed navigation database is:
(a) current (except as provided for by subsection 13 of this CAO); and
(b) appropriate for the region of intended operation and includes the waypoints, navigation aids, and fixes for departure, arrival and alternate aerodromes; and
(c) has been obtained from a supplier holding a Letter of Acceptance in accordance with paragraph 13.3 of this CAO.
       6.2.2For en route and terminal area operations, pilots must:
(a) extract the routes or procedures from the on-board navigation database by name; or
(b) extract waypoints, navigation aids, and fixes by name from the on‑board navigation database; and
(c) comply with the charted route or procedure. Heading-based legs associated with procedures may be flown using manual technique (based on indicated magnetic heading) or, if available, extracted from the aircraft database and flown using area navigation system guidance.
       6.2.3For approach procedures, pilots must:
(a) extract the procedure from the on-board navigation database by name; and
(b) comply with the charted procedure. Heading-based legs associated with procedures may be flown using manual
