Is the ILS CAT III the most technologically sophisticated navigation / landing system available for helping commercial pilots land a commercial passenger aircraft in severe and extremely low visibility weather conditions. Does the airport require special compatible equipment for this system to work properly?

    $\begingroup$ Please clarify what you mean by "auto landing". No aircraft can land fully automatically since, brakes, spoilers, flaps and gear cannot be operated by the auto pilot. $\endgroup$ – Simon Sep 28 '15 at 20:51

    $\begingroup$ @Simon, I beg to differ, the autopilot I helped design and has been tested in flight 3 weeks ago, can :P $\endgroup$ – Federico Sep 28 '15 at 21:09

    $\begingroup$ Your question is a little unclear (what does "sophisticated" mean?) but there are many questions on this site about autoland, ILS and so on. I suggest you review them first and then edit your question to be more precise. This one might be a good start, then this one. $\endgroup$ – Pondlife Sep 28 '15 at 21:41
  • $\begingroup$ @FLIGHTWARS the spoilers and auto brakes must be manually armed. They are not armed by the autopilot (although Federico has built one that does). $\endgroup$ – Simon Sep 29 '15 at 10:20

    $\begingroup$ @simon Well, the autopilot has to be setup for the approach and landing too, so arming those systems isn't really much different, especially since the question asks about the auto land system, and not the auto pilot... $\endgroup$ – Lnafziger Sep 29 '15 at 13:10

Yes ILS equipment for CATIII is the most sophisticated across ILS systems. As people mentioned in comments there are another types of landing systems, which could be more complex. No it is not auto landing system.

It self CATIII is a category of a landing conditions.

Also take a look here What is different between a Cat IIIA, Cat IIIB, and Cat IIIC ILS approach?

    $\begingroup$ ILS creates a straight path for landing. Autoland is a mechanism that follows this path, including managing the flare. Cat III ILS are certified for a better precision and accuracy (as well as protection from interference). However MLS and GPS (GNSS) are far more complex. $\endgroup$ – mins Sep 29 '15 at 8:17
  • $\begingroup$ Thx for links! Edit my answer. $\endgroup$ – Jeka Sep 29 '15 at 8:31
  • $\begingroup$ The question asks if it is the most sophisticated landing system available, not if it is the most sophisticated ILS. :) $\endgroup$ – Lnafziger Sep 29 '15 at 13:12
