17.4 Before using a GNSS-based area navigation system as a substitute or alternate to the conventional navigation aids for terminal operations (SID or STAR) or approach operations phases of flight, the operator or pilot must verify that:
(a) the intended waypoints or procedure(s) can be loaded from the navigation database by name in accordance with Appendix 13; and
(b) the navigation system will fly the procedure as published in the relevant State AIP.

18 MEL
       The operator's MEL must identify any unserviceability that affects the conduct of any PBN operation for which the aircraft is authorised.
Appendix 1 — Requirements for use of RNAV 5

       1                     RNAV 5 navigation eligibility for I.F.R. flights
       1.1RNAV 5 may only be used for PBN by an aircraft if the aircraft meets the eligibility requirements for RNAV 5 as set out in this Appendix.
Note   Air routes may be designed to support RNAV 5 depending on the supporting navaid infrastructure. In Australia, as the navaid infrastructure is limited, RNAV 5 operations are typically dependent on self-contained navigation systems.
       1.2RNAV 5 may be used by an aircraft if the operator has been issued with, or is deemed to hold, an RNAV 5 navigation authorisation under Civil Aviation Order 20.91 as in force immediately before the commencement of this Order.
       1.3An aircraft to which subclause 2.1 of this Appendix applies may be considered eligible for RNAV 5 operations subject to conditions that CASA considers necessary in the interests of safety.
       1.4 An aircraft using RNAV 5 must comply with the operational requirements of this Appendix.
       1.5 Where an operational check, consideration, procedure or task (however described) is required under this Appendix, the operator must ensure that it is performed, given, followed or carried out, as the case may be.
Note   The check, consideration, procedure or task may in practice be performed by the pilot in command, other members of the flight crew, the despatch officer or other operational personnel. However, legal responsibility for compliance is placed on the operator who must ensure that the performance occurs in accordance with his or her established procedures.

2 Application — documents
       2.1If the aircraft is not covered by subclause 1.1 or 1.2 of this Appendix, approval of an aircraft for RNAV 5 operations is required.
     2.2 If subclause 2.1 applies, an operator must be able to supply to CASA at its request, in order to establish eligibility, aircraft airworthiness documents that satisfy CASA the aircraft is equipped for RNAV 5 operations, for example, the AFM, the AFMS or OEM service letters.

3 RNAV 5 system performance
       3.1 For RNAV 5 eligibility, an aircraft's navigation system (the system) must meet the performance, monitoring and alerting requirements for RNAV 5 operations
