Re VFR en route monitoring. I think I would just follow the system used in by far the most successful GA country in the world .
But I am not going to describe it here because you will claim such a system is impossible .
Dick,
I asked a genuine question because I would truly like to know and understand the system you propose, not because I want to say it's impossible. As an international airline pilot, currently working for an overseas airline, I haven't flown VFR in Australia for many years. Nevertheless, I am very interested in the subject and would have appreciated a genuine answer.
