15 Aug 09 2.7.4.9.1 Approach Preparation
In addition to items normally covered by approach briefing for any IFR arrival, CAT II/III checklist should also be reviewed to ensure system status and to review procedures relating to possible autoflight system down grading or malfunctions.
CAT II/III minimum should be set in the DH field of the MCDU PERF APPR page. In case of CAT III without DH, pilot should enter “NO” in the DH field.
All CAT II/III ILS approaches are stabilized approaches. The aircraft should be in the landing configuration and at approach speed by the FAF.
2.7.4.9.2 Task Sharing
Refer to Chapter 13.1.16 – CAT II ILS Approach- Task Sharing. For all CAT II/III approaches, CM1 is PF and CM2 is PNF.
The workload is distributed in such a way that the PF primary tasks are supervising and decision making and the PNF primary task is monitoring operation of the automatic system.
As a general rules, PF-CM1 duties are:
- Controlling the thrust throughout the approach, landing, go-around and rollout
- Making all FCU selections (if any)
- Taking manual control in the event of AP disconnection
- Monitoring flight instruments (when above 350ft AGL) then scanning outside for visual references (except in CAT III approach with no DH) - Making decision to land or to go-around
PNF-CM2 duties are:
- Monitoring flight instruments (head-down) throughout approach, go- around or landing until rollout is completed
- Providing calls for any deviation or failure warning
- Calling barometric heights as required and monitoring auto call-out or calling radio heights including "100 ABOVE"
- Monitoring FMA and calling mode changes as required.
2.7.4.9.3 Visual Reference
The “Continue” call at the minimum by the PIC must be based upon the observation of the following:
CAT II
A segment of at least three (3) consecutive lights being the centreline of the approach lights, or touchdown zone lights, or runway centre-line lights, or runway edge lights, or a combination of these is attained and can be maintained. This visual reference must include a lateral element of the ground pattern, i.e. an approach lighting crossbar or the landing threshold, or a barrette of the touchdown zone lighting.
CAT III A
A segment of at least three (3) consecutive lights being the touchdown zone lights, or runway centre-line lights, or runway edge lights, or a combination of these is attained and can be maintained.

CAT III B with DH
At least one centre-line light is attained and can be maintained. CAT III B without DH
There is no requirement for visual contact with the runway prior to touchdown. If visual contact is lost after the minimum or if touch down cannot be safely accomplished in the touch down zone, go-around should be conducted in accordance with the Normal Procedures detailed in the A320/321 FCOM 3. Deceleration of the aircraft should be monitored to ensure that the aircraft's speed is reduced to less than 100 Kt prior to reaching the point on the runway where the runway centreline lights change to alternating red and white (900 m from the end of the runway).
The aircraft must be at taxi speed prior to reaching the point where the runway centreline lights change to continuous red (300 m from the end of the runway). On reaching this point, CM2 should call “Red Lights”.
No attempt should be made to exit the runway other than at specifically illuminated turn off points.
CM2 should report “Runway vacated” only when the aircraft is clear of the CAT II/III sensitive area. Pilots should exercise care when taxiing under conditions of significantly reduced visibility to ensure that all ATC instructions regarding holding point(s), runway crossings etc, are adhered to. If there is any doubt about the situation, request ATC radar or marshalling assistance.
2.7.4.9.4 Required Aircraft Equipment
Refer to QRH 5.04 for required equipments for Cat II and CAT III approaches.
2.7.4.9.5 Failures and Associated Procedures
The anomalies and failures can be classified into two groups:
- Failures leading to a downgrading of capability as displayed on FMA and ECAM with an associated specific audio warning (triple click).
- Failures that do not trigger a downgrading of capability but are signaled by other effects (flag, ECAM warning, amber caution and associated audio warnings).
It should be noted that some failures might trigger ECAM warnings, cautions and a downgrading of capability.
After any failure or ECAM warning during approach, before deciding to continue or to downgrade the planned approach, crew must check the FMA for landing capability.
Above 1000 Ft AGL:
- Downgrading from CAT III to CAT II is permitted only if: o ECAM actions are completed
