Only those with the price of admission will benefit and only if the
inherenet flaws are fixed (think verification/validation of the
ADS-B link).

As I understand it, the ADS-B radio data link is satellite based, and
subject to cosmic disruption, as well as spoofing, unlike radar. To
base the ATC system on such vulnerable technology is not reasonable.

Are you aware that the FAA's intent is to decommission most of their
radar once ADS-B is operational? ADS-B relies upon aircraft equipped
GPS receivers; radar relies on the physical reflection of radio waves
bouncing off of tangible objects. Which would you prefer to bet your
life on?
