1          Duration

This instrument:

(a)   commences on the day after registration; and

(b)   stops having effect at the end of 30 September 2014.

2          Dictionary

A dictionary for this instrument is in Schedule 4.

3          Application

This instrument applies to an RNAV (RNP-AR) approach in I.M.C. under the I.F.R. conducted for the Qantas trial in accordance with the instructions in Schedule 1.

4          Instructions

The instructions in Schedule 1 are issued.

5          Exemption

(1)     This exemption applies for the Qantas trial.

(2)     Qantas is exempt from compliance with subparagraph (a) (ii) of the definition of authorised instrument approach procedure in subregulation 178 (7) of CAR 1988.

6          Conditions

The Qantas trial must be conducted in accordance with the conditions in Schedule 3.

Schedule 1          Instructions

1     For an RNAV (RNP-AR) approach for the Qantas trial, the pilot in command of the aircraft must use the authorised RNAV (RNP-AR) IAP.

2     The pilot in command may use an authorised RNAV (RNP-AR) IAP only in accordance with the conditions in Schedule 3.

Schedule 2          Qantas trial

The Qantas trial is the trial of authorised RNAV (RNP-AR) IAP as described in the Qantas proposal.

Schedule 3          Conditions

1     An authorised RNAV (RNP-AR) IAP may only be conducted:

(a)   by an approved pilot flying in a manner consistent with his or her level of training for the approach being undertaken; and

(b)   in an approved Boeing 767-300 aircraft that is an RNP-capable Boeing 767‑300 aeroplane for that approach procedure as identified in the AFM; and

(c)   using an RNP AR APCH chart that is satisfactory to CASA.

Note   See definition of RNP AR APCH in Schedule 4.

2     Subject to clause 3, an operation involving an authorised RNAV (RNP-AR) IAP must be in accordance with the Qantas proposal and this instrument.

3     The Qantas proposal, and operations in accordance with it, may be amended only with the approval of CASA.

4     Qantas must obtain written approval from CASA before progressing from Phase 1 to Phase 2, and from Phase 2 to Phase 3, of the implementation plan described in section 7 of the Qantas proposal.

5     Subject to clause 6, an authorised RNAV (RNP-AR) IAP must be conducted to no lower than the RNP AR APCH decision altitude identified on the RNP AR APCH chart for the approach.

6     The decision altitude must not be lower than is permitted by an RNP limitation identified in the approved aircraft’s AFM for the approach being undertaken.

Note   Although the authorised RNP-AR IAP for the approach may permit a lower decision altitude as described in clause 5, 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.

7     Qantas must allow CASA, on request, to attend:

(a)   any simulator training undertaken for an RNP AR APCH; and

(b)   any line flight that includes an RNP AR APCH.

8     At intervals not exceeding 3 months, Qantas must report to CASA in writing the number of authorised RNAV (RNP-AR) IAP flown and, for each of them, each of the following events that occurred after passing NNDP:

(a)   UNABLE RNP message;

(b)   XTK error exceeding 1 x RNP;

(c)   vertical deviation exceeding 75 feet above or below the VNAV path;

(d)   EGPWS warning;

(e)   autoflight system disconnect;

(f)    nav data errors;

(g)   pilot report of any anomaly.

9     Qantas must:

(a)   prepare an incident form and a feedback form for authorised RNAV (RNP‑AR) IAP; 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 Qantas reports to CASA.

10     Qantas must immediately inform CASA in writing of any matter concerning an authorised RNAV (RNP-AR) IAP that relates to the safety of such approaches.

11     An authorised RNAV (RNP-AR) IAP must not be used to satisfy any planning requirements for alternate aerodromes unless approved by CASA in writing.

12     Before commencing an authorised RNAV (RNP-AR) IAP, the pilot in command must ensure that:

(a)   at least 2 of the approved aircraft’s GPS receivers are operational; and

(b)   updating of the FMS by DME is inhibited; and

(c)   the RNP type for the approach is correctly loaded from the current approved navigation database or selected by the flight crew.

13     At all times during an authorised RNAV (RNP-AR) IAP, the pilot in command must ensure that:

(a)   for operations below RNP 0.30, the approach is flown by autopilot in LNAV and VNAV mode; and

(b)   for operations equal to or greater than RNP 0.30, the approach is flown by flight director in LNAV and VNAV mode; and

(c)   the approach is flown in accordance with the current approved navigation database setting out that approach; and

(d)   the navigation performance showing the ANP is monitored by a serviceable EICAS and the relevant FMC pages, in accordance with the procedures described in the Qantas proposal.

14                 Before trial operations begin for an aerodrome runway not already being utilised for the B737 RNP AR APCH trial, Qantas 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 Qantas to mitigate those effects.

Note   For the B737 RNP AR APCH trial, see CASA 210/10.

15     Qantas must comply with each of the measures mentioned in paragraph 14 (b).

16     Operations below RNP 0.3 are subject to a program approved by CASA at implementation in accordance with clause 4 of this Schedule and the Qantas proposal.
