That should go close to guaranteeing GA and RAA aircraft or sqwawking and on frequency.
Personally, I’ve noticed that some circuit traffic makes a full stop and waits when RPT announces their imminent arrival. Unless I’m close to fuel emergency level (which,is never, so far) I always defer to RPT. Maybe a rule giving RPT a ten minute window might work. No GA operations within the window?
Yet MORE rules?? Come on mate...........If there's anything that an Australian likes more than
more rules, I'm yet to find it.
How about using your effing brains?
