Thanks for your very comprehensive post, PBL, for the first time short and precise, bravo!
Although you put me correctly in class A (I'm not confused with AI man-machine interface), it's rather obvious that other AI-pilots are.
[offtopic]Please excuse that I write AI because this is the more official abbreviation for Airbus Industries, compared to AB=Air Berlin[/offtopic].
It is a simple fact that at least 3 crews ever messed up something very badly. I have argued this way already before.
I have to repeat that it's pretty clear that this error of "forgetting" a TL is not a case of amnesia or any other pathologic reason but because they really *though* that they were acting correctly.
There must be a reason why you don't touch a broken TL/TR. I still haven't found out where and when and why. On a short runway and in an Airbus, that's fatal. But in other cases there must be a reason.
This is what we have to find out and why. This will then be the terminal cause of this accident.
