Minimum Separation on Approach at LHR
Hi all
I've learned that while the minimum separation of aircraft in UK airspace is usually 3nm, in the LHR area this changed not so long ago to 2.5nm. Why and when was this done, and is it wise? To increase / help maintain the present landing rate -- I read somewhere that typically LHR operates to 98.5% capacity (hence the nightmare scenarios we see on tv every time it's a bit foggy).
Any thoughts very welcome.
Best wishes
