The comment about edge cases causes me to think about weather. I don’t think many non-pilots have a good appreciation of how much complex decision making goes into operating in and around inclement weather. Fuel constraints, airport constraints in terms of equipment, weather, and traffic, unreliable forecasting, etc. Theres a lot that goes into it and each aircraft begins making decisions that involve several people, including the on-board pilots.
It seems like you can have one operator for 5-10 aircraft but then suddenly the weather rolls through and every single one of those aircraft needs individual attention and planning. Did you save much by still having an operator/craft? Or do you need more stringent weather requirements to operate these aircraft? Or do you try to have the best of both worlds and eventually the autonomous systems just crash themselves in non-populous areas absent other guidance.
If these systems are largely grounded every time there’s inclement weather I can’t imagine the people who advertise “the world, on time” are going to be too keen on operating them at scale. Dispatch-ability is a major factor in these types of operations.
