13 Implementation program
       13.1 RNP AR operations may only be conducted in accordance with the operator's approved implementation program.
       13.2 If an operator that has not previously conducted RNP AR operations, or RNP AR operations using a particular aircraft type, the implementation program must include limits on operating minima until the operator is able to demonstrate to CASA the capability to safely conduct RNP AR operations without such limits.
Note   The initial operating period with these limitations is determined after consideration of all relevant factors including operator RNAV and VNAV operating experience, the number and frequency of RNP AR operations conducted and the number of non-compliant incidents recorded.
       13.3 The implementation program must have procedures to identify any negative trend in performance or operations, including procedures for monitoring RNP AR operations and collecting relevant data.
       13.4 At intervals as specified in the operator's implementation program, the operator must submit to CASA a report containing a review of operations, including the following elements:
(a) the total number of RNP AR procedures conducted;
(b) the number of satisfactory approaches and departures by aircraft
 and navigation system;
Note   Satisfactory means the approach or departure was completed as planned without any navigation or guidance system anomalies.
(c) the reasons for unsatisfactory operations, for example:
           (i) UNABLE REQ NAV PERF – RNP, GPS PRIMARY LOST, or other RNP related messages; and
 (ii) excessive lateral or vertical deviation; and
 (iii) TAWS warning; and
 (iv) autopilot system disconnect; and
 (v) navigation data errors; and
 (vi) pilot report of anomaly;
(d) comments, both oral and written, from the flight crew.

14 Conditions arising from the implementation program
       14.1 Full RNP AR operational capability will not be achieved until the operator has demonstrated to CASA satisfactory operations at defined stages in accordance with the operator's approved implementation program.
       14.2 An RNP AR authorisation may be issued subject to:
(a) conditions to be met for each stage of the operator's approved implementation program; and
(b) conditions under which the operator may progress to full operational capability.
Note   A suitable implementation program will impose limits on RNP AR operations until sufficient operating experience and flight data has been collected to warrant progress (usually in stages) to full operational capability. Initial operations will normally be limited to day V.M.C., and subsequent phases will permit operations to I.M.C. operations with ceiling, visibility and RNP limits until full capability is achieved. It is intended that a navigation authorisation will be issued before commencement of the operator's implementation program, with specified conditions under which the operator is able to progress to full operational capability.
