Chris,
You got this bit wrong.
I agree...you gotta have radar to make C work!
Australian ATCs have been controlling aircraft in C airspace without radar since ATC began in Oz. Remember that only 15% of Australian airspace is within radar coverage. That means that 85% is outside radar coverage and controlled procedurally.
Mate, we controllers know how to do it. And when ADS-B gets up and running, who gives a big flying fcuk about radar anyway. Maybe Dick would have been better off putting his energy into getting ADS-B up and running. A Dick Smith ADS-B transponder and associated display in every aircraft would go a long way to making our airspace less restrictive for ALL types of airspace users.
