Is this from the A320 Series FCOM any use to you?
''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/MLS 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/MLS 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/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 autoland, 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.''
