Visual cues must be obtained at the applicable DA (baro) (CAT I) or a go-around must be performed.
The crew should be warned that fluctuations of the LOC or GS may occur and thatthe PF should be prepared to immediately disconnect the AP and take the appropriate action should unsatisfactory automatic landing performance occur.
The flight crew is reminded to be vigilant for ILS disturbances when conducting automatic landing on any ILS quality beam in CAT I or better weather conditions when the critical area protection is not assured by ATC.
Being in visual contact with the runway, the crew will decide to continue the automatic landing or to take over manually or to go around. Flare, landing and roll-out must be closely monitored as the crew must be ready to take over in these flight phases as well.
3.8.5 LIMITATIONS
Automatic landing must be approved in the AFM.
At least CAT 2 capability must be displayed on FMA.
AFM limitations must be observed including:
. Glide slope angle,
. Airport elevation,
. Flap configuration,
. Wind limits,
. Required equipment for CAT II must be operative.

4.1 INTRODUCTION
An operator cannot perform CAT II or CAT III approaches or auto-landings unless:
.  the aircraft type is approved for this type of operation (refer to attachment B for the mod/SB status required for those operations) ;
.  the operator has received from his national authorities the operational approval to perform these types of operations. These requirements are reviewed in the preceding Chapter 3.
The aircraft capability to perform these operations is a necessary pre-requisite to obtain this operational approval (refer to AFM).
The airworthiness requirements for CAT II / CAT III approach and automatic landing applied to Airbus aircraft are in compliance with the following:
.  JAR AWO section 1 (auto-land), section 2 (CAT II) and section 3 (CAT III) or its previous regulations applicable at the time of certification.
.  FAA AC 20-57A (auto-land), AC 120-29 (CAT II) and AC 120-28D (CAT lll).
The methodology described in the following only demonstrates compliance with the JAR requirements.
FAA airworthiness approval was obtained by performing additional tests and assessments to comply with above FAA regulations.
It should be noted, however, that the above-listed requirements may be modified in the near future to reflect the JAR/FAR AWO harmonization process, and that the JAR AWO regulations only cover automatic approach and landing using an ILS as precision approach aid.
4.2 AIRCRAFT EQUIPMENT
In order to perform a CAT II or CAT III approach and automatic landing as explained above, the equipment listed in the AFM is required to be operative.
