Lederhosen,
One last time. Any cat I is suitable for autoland, unless it is notified as such, that is by notam, "no autoland" , offset localizer etc. You use judgement as when to use it on busy airports. However even then it can be used. The fact that the protection area might not be clear is covered by the visual segment below 200 feet. If the needles (or the aircraft) jump, then go manual or go around. I agree that with lowering vis the go around option is probably more prudent.
Look, we can all (or should be) manually fly an ils cat I down to minimums. But on the 5th day, fourth stretch, midnight, lousy weather, I definitely state that flying that autoland is more safe.
And yes, never had a low altitude disconnect (autoland) on all Boeing types.
