Which part of a runway performance calculation is un-computable? Yes, there is some subjectivity, but I suggest very little in a highly SOP-driven airline.
It's nearly all computable..but then do you take the runway which gives the least delay in getting airborne or the runway which gives you least track miles - I suppose to save the cost of resolving that sort of conflict I guess we could give HAL a coin ( of low denomination) for that sort of decision

"How would a handful of supervisors perform if presented with a mass turnback from the Atlantic tracks, cf. 9/11"
How about by pressing the big red button labelled "land immediately at nearest suitable airport" such as Boeing is developing now? Coupled of course with the big red button in small airport control towers labelled "I'm full up, don't accept any more automatic aeroplanes". (I note that "developing" doesn't mean "will be achieved soon".)
"Hello Gander, the supervisor in the office pressed the big red button, I've headed your way, burnt fuel getting here - and now you tell me you're full up

".....
because the AI in question won't be developed for many years.
On that we agree, and I also agree it may be developed but who knows when? But until the advent of full,meaningful A.I. I can probably ask HAL more questions than he can ever be programed to answer ( but I promise that I won't! ).
I know that laying off the pilots is no doubt popular in some circles but it shows in some cases at least a deep lack of understanding of a pilot's role on board the aircraft throughout the flight, the current legal situation that the likes of 727gm alludes to (" remote supervisor error" anyone) and a lack of understanding of the current capabilities of AI.
Cheers to all our grandchildren!
That
might be about the right timescale.....
