Bit of common sense here people. You've said that you're flying a Cat 1 ILS. So you've briefed a Cat 1 and then been cleared for a Cat 1. Are people on here seriously suggesting that they will leave the autopilot in and allow the aircraft to autoland? Without a clearance for such and therefore without the sensitive areas protected, or a statement as such from tower and an acknowledgement from you?
As I read it that line in the FCOM gives an allowance for us to fly Cat 2/3 approaches. I agree it isn't particularly clear, perhaps read it as "ILS approach when not flying a Cat2 or Cat3 approach."
