6          Application — approval and specification
          Section 7 applies to the conduct of the Jetconnect trial.
7          Approval and specification for CAO 20.7.1B
(1)     For the definition of RNP-capable aeroplane in paragraph 3.1 of CAO 20.7.1B, Boeing 737‑800 aeroplanes operated by Jetconnect on RNAV (RNP-AR) IAP and IDP are approved for area navigation (RNAV).

(a)   the Jetconnect trial is an approved RNP operation; and
(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 Jetconnect 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 Jetconnect trial.
Schedule 2          Jetconnect trial
              The Jetconnect trial is the trial of authorised RNAV (RNP-AR) IAP and IDP that:
(a)   is described in the Jetconnect proposal and 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 Jetconnect Boeing 737‑800 aircraft that is an RNP-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 Jetconnect proposal and this instrument.
        3     The Jetconnect 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 the 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     Jetconnect 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     Jetconnect must ensure that all RNAV (RNP-AR) approaches and departures are monitored by its Flight Operations Quality Assurance program, which must record at least the following events:
(a)   UNABLE REQ NAV PERF – RNP messages;
(b)   XTK error exceeding 0.05 n miles;
(c)   vertical deviation exceeding exceeding 100 ft above or 40 ft below the VNAV path;
(d)   EGPWS warning;
(e)   autoflight system disconnect;
(f)    navigation data errors;
(g)   pilot report of any anomaly.
        9     Jetconnect 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 at an Australian airport.
      10     At all times during an authorised RNAV (RNP-AR) IAP or IDP, the pilot in command must ensure that:
(a)   for operations equal to or less than RNP 0.30, the approach or departure is flown by autopilot in LNAV and VNAV mode; and
(b)   for operations greater than RNP 0.30, the approach or departure is flown in LNAV and VNAV; and
(c)   the approach or departure is flown in accordance with the current approved navigation database setting out that approach or departure; and
(d)   navigation performance scales showing the ANP are displayed to both pilots.
      11     Before the trial begins for an aerodrome, Jetconnect 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 Jetconnect to mitigate those effects.
      12     It is a condition of the trial that each of the measures mentioned in paragraph 13 (b), that is acceptable to CASA, is complied with.
