.  Fuel planning: additional extra fuel should be considered for possible approach delays.
3.3.3 APPROACH PREPARATION
Aircraft Status Check on ECAM STATUS page that the required landing capability is available. Although it is not required to check equipment that is not monitored by the system, if
any of this equipment is seen inoperative (flag), the landing capability will be reduced. For A300/A310, check AUTOLAND WARNING light. Weather Check weather conditions at destination and at alternates. Required RVR values must be available for CAT II/III approaches. The selected alternate must have weather conditions equal to or better than CAT I. Approach ban Policy regarding an approach ban may differ from country to country. Usually the final approach segment may not be continued beyond the OM or equivalent DME distance if the reported RVR is below the published minima for the required transmissometers. After OM or equivalent, if RVR becomes lower than the minima, the approach may be continued. ATC calls Unless LVP are reported active by ATIS, clearance to carry out a CAT II or CAT III approach must be requested from ATC, who will check the status of the ILS and
lighting and protect the sensitive areas from incursion by aircraft or vehicles. Such an
approach may not be undertaken until the clearance has been received.
Before the outer marker, the required RVR values should be transmitted.
Refer to § 5.10.

Seat position The correct seat adjustment is essential in order to take full advantage of the visibility over the nose. The seat is correctly adjusted when the pilots eyes are in line with the red and white balls located above the glareshield.
Use of landing lights
At night in low visibility conditions, landing lights can be detrimental to the
acquisition of visual references.

Reflected light from water droplets or snow may actually reduce visibility.
Landing lights would therefore not normally be used in CAT ll or CAT III weather
conditions.

CAT II or CAT III crew briefing
The briefing should include the normal items as for any IFR arrival and in addition the following subjects should be covered prior to the first approach:
. destination and alternate weather,
. airfield and runway operational status CAT II / CAT III, etc.
. aircraft systems status and capacity,
. brief review of task sharing,
. review approach procedure (stabilized or decelerated),
. review applicable minima (performance page), go-around
procedure, ATC calls, . brief review of procedure in case of malfunction below 1000ft, . optimum seat position and reminder to set cockpit lights when
appropriate
3.3.4 APPROACH PROCEDURES
The procedures given in FCOM for CAT II and CAT III approaches make the bestuse of the automatic system of the aircraft. A320/A330/A340 FCOM procedures for CAT II/III indicate task sharing between PF and PNF without specifying the real position of PF. This was intentionally done to give the airlines the possibility to adapt their own policy.
