Crazy Voyager is quite right. Sometimes crews will use Autoland in VMC conditions for crew training (It's better to make your mistakes where you can see things going wrong rather than in real CAT II / III conditions).
In this event - you will often be told just for your own information BUT it is nice if the crew tell you whether they require FULL PROTECTION (Use of CAT II / III holding points) or not. If they don't say - it's often a good idea to ask them, so that you can relay that information to the Tower and they can operate accordingly.
