Can you confirm this?

On Airbus (320 and later, don't know for the 300/310), only a CAT IIIB autoland requires 2 AP's.
CAT IIIA and CAT II autoland only require 1 AP.
However, if you have 2 working AP's, procedure requires to engage both of them, even if you are not planning for a CAT IIIB autoland.
Even for a CAT I approach with manual landing, when the AP is still engaged, you should engage both AP's.
And even with an engine failure, Airbus is still CAT IIIA
The bus can also autoland on a CAT I runway as long as:
-The company has checked the ILS beam quality and the effect of terrain
-Wx is CAT I or above
-CAT I minima are used
-At least CAT II is displayed on the FMA
