Instructions — RNP APCH LNAV and RNP APCH LNAV/VNAV on Qantas A330 aircraft
1          Duration
                 This instrument:
(a)   commences on the day after registration; and
(b)   stops having effect at the end of April 2014.
2          Revocation
Instrument CASA 73/11 is revoked.
3          Application
                 This instrument applies to the conduct of RNP APCH LNAV and RNP APCH LNAV/VNAV by Qantas Airways Limited, Aviation Reference Number 216147 (Qantas), on Airbus 330 type aircraft with an RNP-capable RNAV system (the aircraft).
4          Instructions
                 I issue the instructions in Schedule 1.
5          Definitions
                 In this instrument:
AFM means aircraft flight manual.
approved navigation database means a navigation database on a medium approved by the manufacturer of the aircraft as suitable for use with the aircraft.
approved pilot means a pilot employed by Qantas, who has been trained by the approved Qantas CAR 217 training and checking organisation to conduct RNP APCH LNAV or RNP APCH LNAV/VNAV procedures in accordance with the Qantas Flight Crew Operating Manual.
APV means approach with vertical guidance.
Baro-VNAV means barometric vertical navigation.
cross-track error/deviation means the perpendicular distance between the planned flight path of an aircraft and the computed aircraft position as displayed by the aircraft’s navigation instruments.
FAF means final approach fix.
FMS means flight management system.
GNSS means Global Navigation Satellite System.
GPS means Global Positioning System.
LSALT means lowest safe altitude.
LNAV means lateral navigation.
MSA means minimum safe altitude.
ND means the pilot’s navigation display.
method of control means autopilot or flight director.
operator means Qantas Airways Limited.
PFD means the pilot’s primary flight display.
RNAV (GNSS) approach means area navigation instrument approach procedure providing lateral navigation.
RNP means required navigation performance as displayed by the FMS.
RNP APCH LNAV means an area navigation instrument approach procedure providing lateral navigation to a minimum descent altitude (MDA).
RNP APCH LNAV/VNAV means an area navigation instrument approach procedure providing lateral and vertical navigation to a decision altitude (DA).
RNP-capable RNAV system means an area navigation system fitted to an aircraft for which the AFM states that it is capable of meeting RNP 0.3 requirements.
V/DEV means vertical deviation.
VNAV means vertical navigation.
XTK error has the same meaning as cross track error/deviation.
Schedule 1          Instructions
1          RNP APCH LNAV (RNAV (GNSS) Approach)
              The approved pilot of an aircraft operating under the I.F.R. may use an RNP‑capable RNAV system in accordance with these instructions as a non‑precision I.F.R. navigation aid for a published RNAV (GNSS) approach procedure (RNP APCH LNAV), including the related missed approach procedure.
2          RNP APCH LNAV/VNAV (RNAV (GNSS) Approach)
              The approved pilot of an aircraft operating under the I.F.R. may use an RNP‑capable RNAV system in accordance with these instructions as an APV Baro‑VNAV I.F.R. navigational aid for a published RNAV (GNSS) approach procedure (RNP APCH LNAV/VNAV), including the related missed approach procedure.
3          Requirements
     (1)     The AFM must contain a statement that the aircraft is capable of meeting the requirements for RNP 0.3.
     (2)     The aircraft must be operated in accordance with the manufacturer’s instructions.
     (3)     RNP APCH LNAV and RNP APCH LNAV/VNAV must not be used as a navigation reference for flight below the LSALT/MSA, except in accordance with the published procedure.
     (4)     The operator must maintain and validate the FMS navigation database in accordance with the manufacturer’s procedures.
4          Procedures
     (1)     Before commencing an RNP APCH LNAV or RNP APCH LNAV/VNAV procedure, the flight crew must ensure that:
(a)   the required equipment listed in the AFM is serviceable; and
(b)   the RNP APCH LNAV or RNP APCH LNAV/VNAV procedure is loaded from the current approved navigation database; and
(c)   RNP 0.3 is displayed in the FMS.
     (2)     Before commencing an RNP APCH LNAV/VNAV approach the flight crew must ensure that the actual aerodrome surface temperature is within the chart temperature limits.
     (3)     At all times during an RNP APCH LNAV or RNP APCH LNAV/VNAV procedure, the pilot in command of the aircraft must ensure that:
(a)   the approach is flown using a method of control that is in accordance with the AFM and that permits RNP 0.3 operations to be conducted; and
(b)   the approach is flown in accordance with the current company approved navigation database setting out that approach; and
(c)   at least 1 pilot monitors the XTK error and V/DEV as displayed on the ND or FMS; and
(d)   subject to paragraph 5, the approach must be flown whenever practicable, using managed lateral and vertical guidance.
     (4)     The pilot in command of the aircraft must ensure that the RNP APCH LNAV or RNP APCH LNAV/VNAV procedure is discontinued if:
(a)   the navigation of the aircraft exceeds the manufacturer’s stated limits for the RNP 0.3 capability; or
(b)   an alert is displayed indicating that the navigation system cannot meet the manufacturer’s stated limits for the RNP 0.3 capability; or
(c)   the monitored XTK error is greater than 0.3 NM; or
(d)   a tolerance of +/- 75 ft is exceeded with respect to the VNAV path if conducting an RNP APCH LNAV/VNAV procedure.
     (5)     For an RNP APCH LNAV/VNAV procedure, APP NAV must be engaged, FINAL armed and V/DEV scale showing on the PFD before the aircraft reaches the FAF.
5          VNAV path assessment 
     (1)     For a planned approach, the pilot in command may use a vertical navigation path that is derived from the FMS only if the operator has assessed the VNAV as suitable for the approach.
     (2)     The FMS VNAV is suitable for the approach if its path is at or above the path shown in the published chart for the approach.
     (3)     Despite the assessment of the VNAV path as suitable, the pilot in command must observe vertical limitations in the published chart until the FAF.
     (4)     Managed vertical guidance must not be used for an RNP APCH LNAV/VNAV if the actual aerodrome surface temperature is below the chart temperature limits.
