Air traffic (and ground traffic) control are not simple problems. La Guardia has 350k aircraft operations (takeoffs and landings) every year. 1000/day. Peak traffic is almost certainly more than 1 plane every minute. Runways are always in use and the idea that some simple software will solve all the safety problems is not grounded in reality.
> more than 1 plane every minute
Software routinely solves database coordination problems with millions of users per second.
That makes digitization even more important, you sold me.
Hehehehe, grounded.
This isn’t hypothetical, this system just exists in other countries. Digital systems can confirm flight instruction from ATC with zero radio communication.
