Andrewr. I agree 100% with your second last paragraph of post 266.
Written rules in an attempt to get the half wind back system to work.
From time to time I hear atc calling un identified VFR traffic in E and G. What an amateur system.
Nowhere else in the world does this happen. ATCs are clearly worried about being held responsible for a collision. They most likely will be as VFR are obliged to monitor the ATC frequency and it’s on the chart with boundaries shown.
Incompetence at the extreme. Amazing Civil Air accepts this.
