Clearly human-run ATC results in situations like this, so the idea that automated ATC could result in a runway collision and should therefore never be implemented is bad.
You obviously wouldn't authorize the bot to do everything, but you could allow it to autonomously call for stops or go-arounds in a situation like this where a matter of a few seconds almost certainly would have made the difference.
Imagine the human controller gives the truck clearance to cross and the bot immediately sees the problem and interrupts with "No, Truck 1 stop, no clearance. JZA 646 pull up and go around." If either message gets through then the collision is avoided, and in case of a false positive, it's a 30 second delay for the truck and a few minutes to circle the plane around and give it a new slot.
If we aren't confident enough in the automation to allow it to make the call for something simple like a runway incursion/conflict (via total automation), augmentation might be worse than the current approach that calls for 100% awareness by the ATC. Self-driving research shows that at level 2 and level 3, people tune out and need time to get back "in the zone" during a failure of automation.
The reason we won't ever have self-driving cars is that no matter how clever you make them, they're only any good when nothing is going wrong. They cannot anticipate, they can only react, too slowly, and often badly.
We can probably semi automate runway crossing. Someone mentioned red lights when you definitely cannot cross
You're left with a bunch of planes in the sky that can't stay there forever, and not enough humans on the ground to manually land them.
Now image the outage is also happening at all airports nearby, preventing planes from diverting.
How do you get the planes out of the sky? Not enough humans to do it manually.
Now imagine the system comes back online. Does it know how to handle a crisis scenario where you have dozens of planes overhead, each about to run out of fuel? Hopefully someone thought of that edge case.
Remember when all the Waymos were confused by a power outage? Now do that, but with airplanes that will fall thousands of feet and kill hundreds instead of park in the middle of the street.
I'm not saying we shouldn't automate things. We should. But, it's not easy. If it was, we would have done it already.
One of the failure modes should not be “guy forgot thing”.
It already is.
> Now imagine there's a 3 hour outage of the automated system.
Planes divert to another airport, passengers grumble, end of story. Airport closures can and do happen all the time for all kinds of reasons, including weather or equipment malfunctions.
My suggestion is to restrict the use of smaller jets like crj and turboprops. I know airports like LaGuardia can't handle the big jets either, but they could reduce the slots and require a jet that holds, say, 150 people or more. This would result in fewer flights per day to some airports, but reduce overall congestion while still serving the same number of passengers.
