Can the 320 still autoland in cat 3 single, cat 2 or cat 1 conditions or does the autopilot have to be disconnected at the DH in all three cases? I am totally lost with this.
Many thanks..
Are you referring to weather conditions? The autoland system doesn't know what the weather is, just it's own technical status as displayed in the landing capability part of the FMA.
From a technical point of view, if there is a technical downgrade of landing capability, then the automatic landing capability is as per the FCOM-LIM-AFS section as stated above. If the aircraft says Cat 1 in the FMA it can't autoland and the lowest minima for an approach would be ILS Cat 1 minima. However, if the aircraft is fully serviceable and the weather is Cat 1 conditions, the aircraft can still autoland. It doesn't know the weather, company SOPs or ILS category.
