I have ben watching BNE arrivals and departures on " Flt. Radar " and cannot understand why BNE ATC requires such a large separation between arrivals . Sure, the viz was down to 350 metres but even when it was 1000M + they still want
5 minutes between arrivals . I was watching one approach when a QF flight was on a 10 km ILS final and another was waiting at the holding point to take off but they had to wait until the approaching aircraft had landed.
That seems to be a ludicrous amount of time between arrivals and departures even if the viz is low. Surely ATC don't really need such large separations !!!!
