Looks like I am still missing something! The shaded red area on the proposed map is still both north and south of the Thames and I would have expected planes to use both routes in the interests of efficient arrivals. At the moment, I believe that most planes to City using the southern approach route over us anyway. Vectoring spreads them a little if they are busy in order to maintain separation, but this will be the case in the future as well. Lie many others, I'd rather have the intermittent noise of an overflying plane than the continual droan (or worse) of traffic on a busy road.
