AIRPORT FACILITIES
The airport authorities are responsible for establishing and maintaining the equipment required for CAT II/III approach and landing. The airport authorities will activate the LVP procedures as the need arises based on RVR. Prior to planning a CAT II/III approach, the crew must ensure that LVP are in force.
CREW QUALIFICATION
The captain must ensure that both crew members are qualified and that their qualification is current for the planned approach.
SEATING POSITION
The crew must realise the importance of eye position during low visibility approaches and landing. A too low seat position may greatly reduce the visual segment. When the eye reference position is
lower than intended, the visual segment is further reduced by the cut-off angle of the glareshield or nose. As a rule of thumb, an incorrect seating position which reduces the cut-off angle by 1 ° reduces the visual segment by approximately 10 m (30 ft).
USE OF LANDING LIGHTS
The use of landing lights at night in low visibility can be detrimental to the acquisition of visual reference. Reflected lights from water droplets or snow may actually reduce visibility. The landing lights would, therefore, not normally be used in CAT II/III weather conditions.
APPROACH STRATEGY
Irrespective of the actual weather conditions, the crew should plan the approach using the best approach capability. This would normally be CAT III 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:
