If there is an autoland warning, the airplane will not land, nor do an automatic roll out, so if it occurs below DH (with the required visual cues, of course, otherwise we would be going around already) it is captain's decision
On the L1011 type, with fail/operational performance, the statement above is not factual.
The airplane
will autoland...just not as smoothly as you might expect under normal circumstances.
TriStar...in a class of its own...and very
very good, even under adverse circumstances.
I kid you not.
