9.2 Automatic Landing: A319/A320/A321/A330 a/c
CAT II and CAT III autoland are approved in Conf 3 and
Conf Full. Automatic landing is demonstrated: -with CAT II and CAT III ILS beam -with slope angle within (-2.5o, -3.15o) range -For airport altitude at or below: 2500 ft for A320 a/c
9200 ft for A319 a/c 5750 ft for A321 a/c 9200 ft for A330 a/c
-At or below the maximum landing weight -At approach speed (VAPP)
= VLS + 5knots + wind correction for A320 a/c
= VLS + wind correction (minimum wind correction 5 kt and maximum wind correction 15 kt) for A319, A320, A321 and A330 a/c.
Note: For A319 and A330 a/c: under crew responsibility and in case of emergency, auto land can be performed up to 69 tons for A319 a/c and up to 229 tons for A330 a/c. Automatic rollout performance has been approved on dry and wet runways, but performance on snow-covered or icy runways has not been demonstrated.

Chapter 10- Practice Approaches
10.1 Automatic Landing in CAT I or Better Weather Conditions
The automatic landing system’s performance has been demonstrated on runways equipped with Cat II or CAT III ILS approaches. However, automatic landing in CAT I or better weather conditions is possible on CAT I ground installations or when ILS sensitive areas are not protected, if the following precautions are taken:
-
 The airline has checked that the ILS beam quality and the effect of terrain profile before the runway have no adverse effect on AP/FD guidance. In particular, the effect of terrain discontinuities within 300 meters before runway threshold must be evaluated.

-
 The crew is aware that LOC or GS beam fluctuations, independent of the aircraft systems, may occur and the PF is prepared to immediately disconnect the AP and take appropriate action, should unsatisfactory guidance occur.

-
 At least CAT2 capability is displayed on the FMA, and CAT II/CAT III procedures are used.

-
 Visual references are obtained at an altitude appropriate to the performed CAT I approach, otherwise go-around is initiated.

-
 When the crew does not intend to perform an auto land, they should disconnect the AP at or above 80 feet: this altitude being the minimum to take over and feel comfortable.  Nevertheless, for safety purposes, the AP may be disconnected at anytime.

 

10.2 Practice Approaches: To keep the currency of CAT II/III A/B approval of aircraft and crew, practice approaches may be carried out at following airports, when weather conditions above CAT I Minima.
