Most aircraft flying around now, all of the Delta Fleet, have the ability to do an Autoland. We only do it on a few occasions. Category III is when the surface visibility is down to 300' and the fog is right on the deck. Then we are required to use it. Also the airplane itself is required to demonstrate an autoland every 30 days to stay certified. Every now and then you will get a message on the flight plan asking you to do an autoland to keep the aircraft in cert. If its a good one, we mark it as a "Sat" and its good for 30 more days. If its not good, (outside of the paramaters) its an "Unsat" and it goes to maintenance or it is removed from "Autoland" capability till it is fixed. Also every 6 months, the pilot has to demonstrate an auto land.....Yeah I know it sounds dumb to me too. There are three autopilot systems, and they all have to agree and be dead on to continue. Its pretty slick not seeing the runway your landing on. Then the hard part is taxiing.
Almost everything flying from the mid 80's up has that ability, but Delta is one of the only airlines that actually pays for the certification and training to do cat III autolands. Its expensive as hell to train and keep up the equipment, but 4 times in December landing in Atlanta and Jacksonville I used it. It pays for itself in about 2 days with weather like that. Also you feel like the cats ass when everyone else is holding and waiting for the weather to improve or diverting and you come right in and land.
No aircraft, other than the f-18 off the carrier has an auto takeoff that I know of. Also computers fail thats why you need sober pilots, and your an idiot if your gonna risk the lives of others by having a few too many before work.
