Leddee. You should also ask why on earth is radar required to provide a terminal C service.
that such well established and proven CNS/ATM management procedures as promulgated by ICAO draw so much flack for self-confessed "professional" pilots in Australia.
Whaat? It depends entirely on how said CNS/ATM (do I get a prize for using tekko words) is allocated! Oh I remember, A B C D E F and G are all exactly as safe as each other.
