Latency in UAV operation (geeky)

An interesting question about how much latency is acceptable for UAV operation.  My answer, based partly on my radio control flying experience, is that it depends heavily on the context. 200 milliseconds is too long for stunt flying, but not a problem for flying larger UAVs at higher altitudes. The operator has to “dial in” their reflexes to the situation, just as sailors do with different sizes of sailboats.  Here’s an example where low latency is essential:  

A seeming paradox is that longer latencies are acceptable only at higher Stages of Control. (See my draft book for discussion of this concept.)  At the high end (what I call Computer Integrated Flying), if enough knowledge is embodied in the aircraft, the operator can pull back entirely from flying, and switch to “commanding” the aircraft.
