I just don’t understand it. When something can simply be done with existing equipment at no measurable cost
This is a situation where, with proper use of the radar, we could improve safety at no measurable cost.
operations in Class G when under radar surveillance to “close the loop” – and keep the air traffic controller responsible for advising the pilot not to descend below the minimum radar altitude until the pilot reports visual.
I think these say it all.
Clearly an increase in ATC sectors, staff and facilities would be required for ATCs to closely monitor aircraft conducting an instrument approach (possibly at multiple aerodromes simultaneously with typical widespread bad WX) while still providing services to all their other aircraft. In addition,
Quokka has outlined well the inappropriatness of attempting to use radar for this, so an alternative method would need to be implemented, but still require the ATC resources to monitor approaches.
Your constant failure to listen to those with direct experience, knowledge and expertise - dismissing their input when it differs from your opinion as
resistance to change
- reaffirms the waste of time it is to engage in debate here, going over the same issues time and time again.
