As has been stated (over and over), the surveillence aspect is covered in that ATC would revert to procedural control and primary radar surveillance ie. go backwards a few years- inefficient, yes, dangerous, no. Aircraft navigating- well, there are plenty of aircraft using only GPS already.
ferris, your post makes a fair assessment of the scenario I have presented.
I will take issue with the part quoted above though...
I see you make mention that the system would revert to an inefficient, and
non-dangerous state...
a system, aparently, that has less ATC and nav-aids then we currently have... Hmmm...
