Just a couple of points here.
cb radio, They may have inbound and outbound routes at busy GA airports in the USA but I bet they don't have them at the same altitude like here. My next trip over there I will ask again.
A..1bar..Maybe where you fly might be only training but at Parafield most of the states maintenance for GA plus numerous private aircraft are also based here, and with only 2 app/dep points for aircaft OCTA it can get very close and chummy at times. I would much rather see multiple app/dep tracks at various altitudes thanks, where you do not desend until under instruction and sight of the tower ie class D.
Why not wait until we all know what is being proposed before flying off at the handle with all this doom and gloom, it will never work jargon.
