Thanks guys I can now see your point of view.
RTB RFN well I would be pretty "pissed" in the environment that I work in if a Controller didn't intervene to prevent a TA developing into an RA
Is'nt that what there employed for.
What is the problem with that, is Airservices Australia just going to sit there and watch an MAC and then hide behind some legal jargon which prevents them from doing anything.
That's basically what you guys are saying from what I can deduce.
