6.2 AIRCRAFT REQUIREMENTS
6.2.1 CERTIFICATION STATUS
The A320-211 in the airline fleet are certified for the intended operations in compliance with:
. JAR AWO 1 and AC 20-57 A for automatic landing, . JAR AWO 2 and AC 120-29 for CAT II, . JAR AWO 3 and AC 120-28 C for CAT III.
Automatic approach with DH below 200ft but not less than 100 ft
The A320-211 is certified to conduct CAT II approaches provided that:
. at least one AP is coupled down to DH,
. CAT 2, CAT 3 SINGLE or CAT 3 DUAL is displayed on FMA.

The CAT II approach capability has been demonstrated on CAT II or CAT III ILS quality beam.
A CAT II automatic approach can be followed, if visual references are sufficient, by a manual or an automatic landing.
Automatic approach with DH below 100ft but not less than 50ft
The A320-211 is certified to conduct fail passive CAT III approaches provided that:
. at least one AP is coupled for approach and automatic landing,
. CAT 3 SINGLE or CAT 3 DUAL is displayed on FMA. The CAT III approach capability has been demonstrated for CAT II and CAT III ILS quality beam.
Automatic approach with DH below 50ft but not less than the MABH or NO DH
The A320-211 is certified to conduct fail operational CAT III approaches provided:
. both AP are coupled for approach, automatic landing and roll-out;
. CAT 3 DUAL is displayed on FMA,
. a DH is established based on the MABH of 17ft or if NO DH is used
the minimum RVR is not less than 75m. The CAT III approach capability has been demonstrated for CAT II and CAT III ILS quality beam.
In addition, for both CAT II and CAT III operation, the relevant AFM limitations,
normal procedures and abnormal procedures will be observed.
AFM extracts are given in appendix to this file.

6.2.2 REQUIRED AIRCRAFT EQUIPMENT
The CAT II or CAT III capability is available provided the equipment listed in the relevant AFM list of equipment is operative.
AFM extracts are given in appendix to this file.
If the aircraft is dispatched with equipment inoperative, the MEL may preclude CAT II or CAT III operations as appropriate.
6.2.3 MAINTENANCE REQUIREMENTS
On all Airbus aircraft, CAT II / CAT III capabilities are inherent functions of the basicdesign standard. Therefore, related tasks are covered by the Airbus Maintenance Program. There is no special recommendation for scheduled maintenance tasks or functional checks to assure CAT II / CAT III capabilities.
A program for unscheduled maintenance is established based on the AirbusMaintenance Manual to advise corrective actions / procedures necessary after an automatic landing failure or associated component failure.
A reliability program for the required equipment has been established to monitor the system operational status.
The aircraft status is primarily governed by status messages displayed on ECAMSTATUS page and FMA display of capability. However, crew entry in the Technical Log Book will take precedence.
