Bloggs, I support class C where safety requires it- always have.
But it needs to be properly manned and equipped.
Your so called "near misses" were not. At Brisbane both aircraft were on the radar frequency and the RA would not have been generated if the correct procedures were followed.
In Launy the VFR aircraft received a radio alerted traffic advisory on two frequencies and always had the other aircraft in site. Or are you now saying that alerted see and avoid does not give acceptable safety levels?
