. RVR is at least equal to CAT I minima,
. briefing is amended to include CAT 1 procedure and DH.
. the decision to downgrade is completed above 1000ft AGL,
Note: switching from one AP to another before 1000ft AGL is permitted.
Below 1000ft and above DH (for CAT 2 or CAT 3 SINGLE) or above AH (for CAT 3 DUAL) a go-around must be performed in case of:
. ALPHA FLOOR activation,
. loss of AP (cavalry charge),
. downgrading of capability (triple click),
. amber caution (single chime),
. engine failure.
At 350ft* RA
LAND must be displayed on FMA and runway course must be checked. If runway course is incorrect or LAND does not appear, a go-around must be performed. If conditions permit, and according to airline policy, a CAT ll approach with AP disconnection no later than 80ft may be performed.
LAND is displayed if LOC and GS track modes are active and at least one RA is available. These conditions need to be obtained no later than 350ft AGL to allow a satisfactory automatic landing.
* Depending on terrain profile before the runway LAND mode may appear at lower height. This can be acceptable provided it has been demonstrated that automatic landing is satisfactory.
At 200ft RA and below
Any AUTOLAND warning requires an immediate go-around.
If visual references are sufficient and a manual landing is possible, the PF may
decide to land manually.

At flare height

If FLARE does not come up on FMA, a go-around must be performed.
If visual references are sufficient and a manual landing is possible, the PF may
decide to complete the landing.

After touchdown

In case of anti-skid or nose wheel steering failure, disconnect AP and take manual
control.
If automatic rollout control is not satisfactory, disconnect the AP immediately.

3.4 FLIGHT CREW TRAINING AND QUALIFICATION
It is essential that flight crews are trained and qualified in all aspects of All Weather Operations appropriate to the intended operations. This process is divided into two parts:
. Ground instruction in the background and philosophy of all-weather operations. . Flight training which may be carried out in approved flight simulator and/or during airborne training.
This ground and flight training must be conducted in accordance with the requirements of the operational regulation, which are described in
. ICAO All Weather Document n°9365 AN/910 which represents the basic aeronautical requirements for CAT II and CAT III. . US/European regulations:
*  
AC 120-28C and D (CAT Ill) and AC120-29 (CAT II) for airlines under FAA authority.

*  
JAR-OPS for operators under JAA authority.

* 
 ECAC Document n°17

*  
CAA CAP 359

*  
DGAC Decision 3437 (2106/1975) etc.

Although the wording and format of these documents are different, the requirements are quite similar. Only two training programs and qualification requirements (FAA and JAA) are described in this chapter. Moreover, to be easily accessible, the different requirements are presented in separate paragraphs:
