I'm with LadyAtco; although the technology presentation is impressive.
Where I seriously object to the concept espoused is in the 1 controller multiple airport scenario. Even if this idea is restricted to VERY quiet airports I simply cannot accept that it is safe. There are too many considerations & variables involved to make this practice acceptable.
In my view, this is an example of the Regulators abandoning their responsibilities in order to appease airport operators etc.
I was schooled in the ATC "Fail Safe" philosophy. I cannot see how this scheme could possibly be Fail Safe.
