To add to that, just in case you're not aware. You can also perform a "practice" autoland using a CAT 1 ILS, into an unapproved airfield provided the aircraft is up for it, you are in VMC and are prepared and ready to take over. You do not need to request this from the tower or even announce a "Practice Autoland" (always a good idea to check the AIP/airport info charts to be certain).
Though, I did once hear a British charter request the "LOC area to be protected" (in bright VMC) because he was performing a practice autoland
