The problems are of course set out above, but it all comes down to the fact that it is Class A.
I could get more across the aerodrome if it was Class D. One of the other problems of course is that whilst we can separate visually in the vicinity of an aerodrome, we would have to phone arrivals or departures regarding the traffic so that traffic info can be passed. Sometimes it is simply too busy for that.
What about the congested areas on the ground - anything east of LHR is pretty built up is it not?
If it were Class D, we could even have more than one aircraft routeing BUR-ASCOT at a time!
