vertical deviation means the vertical difference between the indicated position of the approved aircraft and the planned position as displayed to the flight crew by the FMS and on the V/DEV scales of the primary flight displays.
XTK error (lateral deviation) means the cross-track (lateral) difference between the indicated position of the approved aircraft and the planned position as displayed to the flight crew by the FMS and on the L/DEV scales of the primary flight displays.
This instrument applies to the instructions for the conduct of an RNP-AR approach or departure under the I.F.R. in Schedule 1 by Jetstar.
The instructions in Schedule 1 are issued.
Jetstar is exempt from compliance with subparagraph (a) (ii) of the definitions of authorised instrument approach procedure and authorised instrument departure procedure in subregulation 178 (7) of CAR 1988 when undertaking the Jetstar trial.
7 Application — approval and specification
Section 8 applies to the conduct of the Jetstar trial.
8 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, Airbus 320-232 and Airbus 321-231 aeroplanes operated by Jetstar on
RNP-AR IAP and IDP are approved for area navigation (RNAV).
(2) For subparagraph 12.1.1 (b) and paragraph 12A.5 of CAO 20.7.1B:
(a) the Jetstar trial is an approved RNP operation; and
(b) the appropriate RNP containment is twice the RNP type used for the
Note Under clause 7 of Schedule 2, it is a condition that an RNP-AR departure must be conducted using an RNP type not less than any RNP limitation specified by the aircraft manufacturer for the departure being undertaken.
The Jetstar trial must be conducted in accordance with the conditions in Schedule 2.
Schedule 1 Instructions
1 For an RNP-AR approach or departure, the pilot in command of the aircraft must use the authorised RNP-AR IAP or IDP.
2 The pilot in command may use an authorised RNP-AR IAP or IDP only when conducting an RNP-AR approach or departure for, and in accordance with, the Jetstar trial.
Schedule 2 Conditions
1 An 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 or Airbus 321-231 aircraft that is an RNP-capable aeroplane for that approach or departure as specified by the aircraft manufacturer.
2 Subject to clause 3, an operation involving an 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 RNP-AR approach must be conducted to no lower than the RNP-AR decision altitude identified on the authorised RNP-AR IAP for the approach unless the associated visual reference has been established.
5 An RNP-AR approach must be conducted to a decision altitude not lower than that determined by any RNP limitation specified by the aircraft manufacturer 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 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 Subject to clause 7, an RNP-AR departure must be conducted with not lower than the minimum ceiling and visibility identified on the authorised RNP-AR IDP for the departure.
7 An RNP-AR departure must be conducted using an RNP type not less than any RNP limitation specified by the aircraft manufacturer for the departure being undertaken.

13 Before commencing an authorised 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 correctly loaded from the current approved navigation database or selected by the flight crew.
14 At all times during an authorised RNP-AR operation, the pilot in command must ensure that:
(a) the approach is flown in final approach mode with the autopilot engaged; and
(b) the departure is flown in NAV mode with the autopilot engaged; and
