Hang about ACMS
I do not know Hooters but he is advocating change to the airspace classification, just as I am.
The system is broken - but not at the workface level.
It is broken at the management level in both OAR and Airservices.
By definition, IFR aircraft can not separate themselves visually and giving them traffic does NOT solve the problem.
IFR aircraft are frequently constrained to fly one flight path and one only - they have no choice; consider an instrument approach for example.
Your are right to this extent: FOUR PEOPLE ARE DEAD because the SYSTEM IS A FAILURE.
Fix the system not blame the worker who is only permitted to dish out traffic information.
