Will it do the same on a grass strip, which some pilot did without engines in the Houston area?
Can it do a perfect belly landing like a Polish pilot did some years ago?
Can it land in the Hudson?
All of those pilots had massive experience beyond button pushing auto-piloted aircraft.
I think (hope) this is just a typical marketing program which is not actually going to happen.
Moreover, it is easy to find at least 30 successful landings under the above conditions, while the situation you are referring to has about 4 cases, 2 of them contested.
Also, locking the cockpit doors on airliners is stupid in my opinion.
Aviation industry follows safety in redundancy principles. So on top of all the redundancy they are going to add in a system like this, I assume pilot will be part of the redundancy too.
Perhaps they can remove co-pilot soon. But, it will take a few years to go without any pilot. Even then perhaps they start with cargo airlines. I assume they can use a ground station as an emergency pilot like how military drones work.
I think if you get must of the major airports covered that's still good enough. But, if I understood this article correctly, what Airbus is trying now is to make it happen without those ground requirements. And I'm sure they do not expect to cover every airport and runway to begin with.
