I would say that it is largly to do with the fact that because Class A obliges standard separation, it effectively removes the need to be giving traffic info. to the big boys on the littluns which could pass as close as they like, VFR. We don't need that workload on what are already overly busy frequencies and nobody in a big public transport aircraft needs to be distracted from the most dangerous part of their flight spending time looking out for traffic. . .. .With the wx in this country being 'difficult', shall we say, making the London CTR class A keeps life much simpler for all of us. Can you imagine the danger of a VFR trying to cross 'through' the ILS with constant 3 miles spacing at 160kts? It would be asking for trouble. At Gatwick where the standard spacing is more usually 6 miles handling VFRs is not as difficult. Were it ever to get another runway and go to 3 miles as a standard spacing I think they would need to look at class A here too. . .. .As far as Jersey is concerned, I haven't got clue! . .. . <img border="0" title="" alt="[Smile]" src="smile.gif" /> . .. .Point 4
