Yes, the 1-11 510ED has autoland, none of the other 1-11s do. Switch on 'Prime Land' once established on the ILS.
Autoland isn't the easiest thing to do well in FS and it's probably not fair to expect too much of it on most models. It's usually a bit of fun.
Automation was the main feature of Tridents though, so that model was developed specifically to do those bits as well as possible.
It had a ridiculous amount of effort put in just on the autoland, so you can expect it to handle it better than most. It can even handle a stiff crosswind.
A half decent IAS mode as well, which is harder than autoland!
It was work that only got done because it seemed vital at the time. I'd never take on something that tricky these days, no chance.
The Trident's autoland code ended up in the 1-11 510ED & VC10 models too.
