The operational radius is simply a suggestion on how far the drone would reasonably operate. Not how it actually flies in practice.
This whole line of discussion is actually a nice microcosm into the very different philosophical approach to AI and automation between the west and China.
In the west, the goal is to remove the human entirely to do the same job to maximise profits for the landlord; whereas in China, the focus is how to improve efficiency and productivity so the same person can do more.
The western method keeps the pie the same and carves out a bigger slice for the landlord at the expense of the worker; while the Chinese method grows the pie so everyone gets more pie.
I leave to each of you to decide for yourselves which is the superior method.
