OK, thanks for all the responses

Firstly, No Fly Zone, if I did that my airline would fire me. As a dedicated pilot I like nothing more than to do things myself, I don't like handing control over, I'm a control freak, whatever, I think most pilots are, but the airline decides at the end of the day.

To summarize what people have said:

1. Insert ILS freq. plus Course in RAD NAV
2. Activate APRCH Phase, regardless of which Airport + Approach is set in the box, insert the minima in the box
3. As per airbus logic all speeds displayed on PFD are based on real time weights using FAC, so technically one can fly managed speeds and have the aircraft decelerate correctly? Is that the case? Little confused about this, some say that one must decelerate using selected speed, including setting final apprch spead manually?
4. At some stage in the approach RWY/ILS Mismatch warning will appear on MCDU scratch pad.

However, aircraft should intercept ILS as normal and fly all the way down, the questions which still remain are these:

1. JABARRA you said that LAND green will not appear and AP will disconnect at 400ft. I don't really see why. You have a valid ILS beam, all the equipment at the airport is working fine. LAND mode simply means that the FMS is now locked onto the beam and no manipulation of the FCU will disengage it other than a G/A. So why should you not get LAND? And technically why can't one continue for an autoland? I would need to look into the books more closely but speaking off the top of my head; so long as the LOC and GS signals are valid and the RA works whats to stop a Autoland? What more does the aircraft need?
2. Regarding a G/A. Obviously there will be no lateral flight plan so if one was to do a G/A the questions are
a) would G/A mode activate?
b) would the THR RED and ACCEL be what was set is the PERF G/A page for the approach in the box (which isn't the one that is being flown)

Thanks
