The PMDG FSX MD11 has ILS autoland. I tell you, I was never a fan of heavy metal, I have always been into fighters, I love my Aerosoft F16, Accel FA18 and my Cap Sim FA18D, but this MD11 is so cool. All of the systems are modeled and this plane will land you right on a runway.
http://www.precisionmanuals.com/pages/product/md11.htmlThe only problem that I have come across is that there are airports where the ILS is not active for some reason. An example is that at KHOU you can not do an autoland on 12R, but you can on 30L and it is the same runway! Go figure.
The CS MD80 Pro will also autoland, but I do not think it is fully automated like the PMDG MD11. Also I have the CS MD80 Pro, but I have not gotten into learning the system yet, so I can not tell you what the autoland experience is like, but the manual does say that it has autoland.
