APPROACH STRATEGY
Irrespective of the actual weather conditions, the crew should plan the approach using the best approach capability. This would normally be CAT 3 DUAL with autoland, depending upon aircraft status. The crew should then assess the weather with respect to possible downgrade capability.

1 GO AROUND STRATEGY
The crew must be ready mentally for go-around at any stage of the approach. Should a failure occur above 1 000 ft RA, all ECAM actions (and DH amendment if required) should be completed before reaching 1 000 ft RA, otherwise a go-around should be initiated. This ensures proper task sharing for the remainder of the approach. Furthermore, refer to FCOM 4.05.70 for failures and associated actions below 1 000 ft RA that should lead to a go-around.
APPROACH BRIEFING
Before commencing a CAT II/III approach a number of factors must be considered by the crew.
In addition to the standard approach briefing, the following points should be emphasised during an approach briefing for a low visibility approach:
? Aircraft capability
? Airport facilities
? Crew qualification
? Weather minima
? Task sharing
? Call-outs
? Go-around strategy
APPROACH PROCEDURE
Applicable to: ALL
TASK SHARING
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 the operation of the automatic system.
The PF supervises the approach (trajectory, attitude, speed) and takes appropriate decision in case of failure and at DH.
Since the approach is flown with AP/FD/A/THR, the PF must be continuously ready to take-over:
? If any AP hard over is experienced
? If a major failure occurs.
? If any doubt arises
The PF announces "LAND", when displayed on FMA.
 
NORMAL OPERATIONS
PRECISION APPROACH
 

 
The PNF is head down throughout the approach and landing. The PNF monitors:
? The FMA and calls mode change as required (except "LAND")
? The Auto call out
? The aircraft trajectory or attitude exceedance
? Any failures
The PNF should be go-around minded. SOME SYSTEM PARTICULARS
? Below 700 ft RA, data coming from the FMS is frozen e.g. ILS tune inhibit.
? Below 400 ft RA, the FCU is frozen.
