I have never heard the term 'semi-automatic landing', and I would suggest that there may be no such thing. You can have an aircraft set up for an autoland in Cat 1 or better conditions and carry out an AP/AT disengagement and manual landing at any point in the approach (although it's not recommended below DA). In conditions below Cat 1, the only time a manual landing would be carried out is if the flare function failed but there were sufficient visual references to land and stop the aeroplane manually. All other failures would prompt a go-round.
However, I have no Airbus experience (as yet - now off to the A340 in June), so maybe there's some function in the Eurolectric Jet, that I'm not aware of, that fits this scenario?
