I agree with your comments Pprune Radar but I also think these acceptable separations were deemed acceptable before TCAS was established. TCAS as we have all seen in many different scenarios can add major complications in certain circumstances as well as add a very useful safety barrier. Perhaps the authorities should have another look at these things. It's always small, seemingly insignificant things that cock us up in this game.
(BD - I think it was MIL ATC that we are often in contact with but I can't remember exactly.. My point was that I think we have good relations but not a lot seems to come from observations made.)
Cheers for your thoughts guys....
