Yet another Autoland question

[EdwardSm 5]

A friend in my VA who has the excellent 737NGX was attempting an autoland on 22L at KBOS. He said it would not take and so landed it by hand. My thoughts, as a non-expert, are that 22L isn't CAT II or CAT III so there is no autoland possible on that one runway. Another member of the VA said it doesn't matter what CAT it is because FSX doesn't know the difference. Can anyone explain why he could not autoland if he was properly setup? Was it (1) just a fluke, did he (2) do something wrong, or is the 737NGX (3) so accurately modeled that 22L of KBOS can't have an autoland despite what FSX thinks?

No. 2 In FSX, as long as a runway has an ILS then an autoland is possible.

You can, and it is legal to (in visual conditions), perform an autoland on any runway with ILS.
