I don't know if my earlier reply to this question made it to the group or
not, but the autoland systems in the current family of Boeing jetliners
are set up to fly most of the approach in a crab and then transition to
the wing-down method for the last part of the final approach, flare, and
touchdown.  That is also the method used by every airline pilot I've ever
flown with when they hand-fly the approach, which is almost all the time.
