Full autoland should work if the ILS frequency is correct and you get the green box and the dual land announcement subsequently. As long as you chose an ILS approach in the FMC there is no further intervention required, FMC-wise. So the FMC guide is pretty complete. It has nothing to do with the FMC, except the above mentioned approach.By the way, Boeing does it the same way, no further FMC action required. Select the correct speed, make sure you have both or all three autopilots connected and wait until the plane drops to the concrete.Full autoland, including flare and rollout will never work without the ILS frequency. Autoland depends mainly on the correct frequency, your green box below the engine gauges and the dual land announcement on the PFD. If this dual land doesn't show up, you'll get an "approach only" warning, making a successful autoland impossible.
