I suspect that the Alaska 727-200ADV were part of the group of airplanes that Alaska got from Singapore 727-212ADV with the -17 engines. They were exceptionally well equipped with AT, ABS and believe auto speed brakes as well. High gross weight somewhere around 198K. Do not recall ever seeing an auto land option in the 727 but it might have been an option. Looking at My Boeing Fleet and it does not show up when doing a word search
