We have RAs in Class A airspace for crying out loud.
But not without a mistake; or without real separation being applied and a flase alarm generated (i.e. closure rates too high, a predictive error)
However, the fact remains that under this system there is still greater POTENTIAL for this type of incident than under the old system. Greater potential will result in a greater number of incidents and a greater number of incidents will ultimately result in a greater number of accidents.
Absolutely, bacause you have RAs inside Class A and Class C doesn't mean that it is safe to have them inside class E, as Mr.Anderson has implied.
Mistake free accidents can occur in E; the same cannot be said of Class A or C.
