Hey Ijut,
thanks for the reply.
Every place in the world could be more efficient, if run by bean counters.
Unfortunately, we have to roster for the worst case scenario, not the other way around.
Most inefficient thing they ever did in Oz was to introduce teams and team leaders....upped the numbers by a load.
I believe they have now worked that out and have gone back somewhat to the older style of rostering.
BTW...I indeed remember those big procedural sectors...worked them for many a year before moving to the 50/50 radar arrivals spots.
Also I have mentioned to Dick, many ways to skin a cat, huge numbers of procedural separation standards..used to use most of them!
Personally I like the ICAO 15 degrees 15 miles off a navaid.
I'll let the maths genius's out there work out how far apart you are at 15 miles...needless to say it is significantly less than 5 radar miles.
Cheers
