A320 Successful Autolands?

[electricdeathjet]

Just wondering what the parameters are for a successful autoland on a 320? What is considered to be un-successful? What sort of deviation from the center line is acceptable? (For you comedians out there please dont say main wheels in the grass!)
I haven't been able to find out anything listing what is deemed acceptable or not.
Any pointers or links would be appreciated.

Landing within the desiginated landing zone, no autoland light illuminated, firmness is subjective. These were the parameters our company used.

Have a look at EASA CS-AWO book 1 subpart 1.

Also depend on which engines you have - the characteristics are quite different between them
