(b)   the appropriate RNP containment is at least 2 times the RNP type specified in an approved aircraft’s AFM for the procedure.
8          Conditions
          The Jetstar trial must be conducted in accordance with the conditions in Schedule 3.
Schedule 1          Instructions
      1     For an RNAV (RNP-AR) approach or departure, the pilot in command of the aircraft must use the authorised RNAV (RNP-AR) IAP or IDP.
      2     The pilot in command may use an authorised RNAV (RNP-AR) IAP or IDP only when conducting an RNAV (RNP-AR) approach or departure for, and in accordance with, the Jetstar trial.
Schedule 2          Jetstar trial
       The Jetstar trial is the trial of authorised RNAV (RNP-AR) IAP and IDP that:
(a)   is described in the Jetstar proposal accepted by CASA; and
(b)   complies with the conditions mentioned in Schedule 3.
Schedule 3          Conditions
      1     An RNAV (RNP-AR) approach or departure may only be conducted:
(a)   by an approved pilot flying in a manner consistent with his or her level of training for the approach or departure being undertaken; and
(b)   in a Jetstar Airbus 320-232 aircraft that is an RNP-AR capable aeroplane for that approach or departure as identified in the AFM.
      2     Subject to clause 3, an operation involving an RNAV (RNP-AR) approach or departure must be in accordance with the Jetstar proposal and this instrument.
      3     The Jetstar proposal, and operations in accordance with it, may be amended only with the approval of CASA.
      4     Subject to clause 5, an RNAV (RNP-AR) approach must be conducted at no lower than the RNAV (RNP-AR) decision altitude identified on the authorised RNAV (RNP-AR) IAP for the approach.
      5     An RNAV (RNP-AR) approach must be conducted at no lower than RNP limitation identified in the approved aircraft’s AFM for the approach being undertaken.
Note   Although the authorised RNAV (RNP-AR) IAP for the approach may permit a lower decision altitude as described in clause 4, the actual altitude must not be lower than the RNP capability of the aircraft at the time of the operation, taking into account unserviceabilities etc.
      6     An RNAV (RNP-AR) departure must be conducted using an RNP type not less than the RNP limitation identified in the approved aircraft’s AFM for the departure being undertaken.
      7     Jetstar must allow CASA, on request, to attend:
(a)   any simulator training undertaken for RNAV (RNP-AR) approaches and departures; and
(b)   any line flight that includes an RNAV (RNP-AR) approach or departure.
      8     At intervals not exceeding 3 months, Jetstar must report to CASA in writing the number of RNAV (RNP-AR) approaches and departures flown and, for each of them, each of the following events that occurred after passing the initial approach fix:
(a)   NAV accuracy downgrade;
(b)   XTK error exceeds 0.2 NM;
(c)   vertical deviation exceeding 100 ft above or 40 ft below the VDEV path;
(d)   EGPWS warning;
(e)   autoflight system disconnect;
(f)    nav data errors;
(g)   pilot report of any anomaly.
      9     Jetstar must:
(a)   prepare an incident form and a feedback form for authorised RNAV (RNP‑AR) IAP and IDP; and
(b)   tell the flight crew, and other persons involved in such an operation, about the forms and make them available to those people; and
(c)   encourage them to complete the forms, without fear or favour, for Jetstar reports to CASA.
    10     Jetstar must immediately tell CASA of any matter concerning an authorised RNAV (RNP-AR) IAP or IDP that relates to the safety of such approaches or departures.
    11     An authorised RNAV (RNP-AR) IAP or IDP must not be used to satisfy any planning requirements for alternate aerodromes.
    12     Before commencing an authorised RNAV (RNP-AR) IAP or IDP, the pilot in command must ensure that:
(a)   both of the approved aircraft’s GNSS receivers are operational; and
(b)   updating of the FMS by VOR/DME is inhibited; and
(c)   the RNP type for the approach or departure is loaded from the current approved navigation database and selected by the flight crew.
    13     At all times during an authorised RNAV (RNP-AR) IAP or IDP, the pilot in command must ensure that:
(a)   the approach or departure is flown by autopilot in final approach or NAV mode; and
(b)   the approach or departure is flown in accordance with the current approved navigation database setting out that approach; and
(c)   navigation performance scales showing the EPE are displayed to both pilots.
    14     Before the trial begins for an aerodrome, Jetstar must give CASA a study, acceptable to CASA, of:
(a)   the likely environmental effects of the conduct of the trial at the aerodrome; and
(b)   the measures that would be taken by Jetstar to mitigate those effects.
    15     It is a condition of the trial that each of the measures mentioned in paragraph 14 (b) that is acceptable to CASA is complied with.
