Denti: As if that isn't enough Boeing offers the installation of a head up guidance system which allows manually flown CAT IIIa approaches, in fact the 737 classic was the first airliner which had that feature available although that wasn't widely known.
Actually, the 737-200 wasn't first with Cat IIIA HUD; it was the Alaska Airlines 727-200 fleet with the Flight Dynamics HGS. The need for an expensive inertial system doubled the cost and limited the sales. Southwest went on to certify it in the 737-200.
Autoland gets you down in reduced vis; HUD lets you take off also. I don't think you'l find a pilot experienced with HUD who would prefer Autoland to HUD.
