So, NASA, is in the process of working on some of this. They’re trying to come up with a new ATC model which will work better for drones / eVTOL air taxis / etc

So, NASA, is in the process of working on some of this. They’re trying to come up with a new ATC model which will work better for drones / eVTOL air taxis / etc. Some of the ideas are around “carving” out corridors, where you would be able to fly, and this corridor could be reasonably large (across multiple towers today). The other interesting thing is hierarchical ATC automation. So, normal ATC would still exist, but they would interact with a tier of controllers who are responsible for them interacting with UAVs. A lot of this apparently came from the idea that eVTOL is the future, and we will all be commuting to work in an electric airplane.
