BH : you are right,the plane won't do an autoland on one autopilot,but on classics,I think it won't disconect by itself,it will just slamm on the rwy,having no flare capability.The AT will retard though,at 27 feet,so a very hard touchdown.
Regarding your pertinent answer about the crab position,one question:why not trying to use rudder peddal during flare,to remove the crab angle? Never tried that,just a question.
And also,the book says that you can toucdown in a crab position,then removing crab,on a wet rwy.I did this once,on a dry rwy,
,due to very strong crosswind with gusts,not the nicest soft landing,but a good one.We did taxi after that
