I wonder if we are reading too much into these charts. Interestingly the map of the 'existing' approach paths appears to be wrong in so far as it shows the hold (the racetrack pattern) for City near Southend. In fact it is at Swanley, and it is because we are on a direct line from Swanley to a point about 5 miles short of the runway (where the planes line up for their final approach) that results in most City arrivals for runway 10 flying over us at the moment. I think it is important to remember that runway 10 is probably used for only about 30% of the time - most of the time they are landing to the west on runway 28 and we don't see or hear them at all.

My biggest concern about aircraft noise is the early morning arrivals of flights at Heathrow, the first of which are at about 0430 and can be annoying in the summer when the windows are open.

I don't see any likelihood of affecting the proposals in any way so apart from spreading a bit more knowledge of what is going on, I don't think the issue is worth worrying about.

BTW, if anyone is really interested, they can buy a receiver device to plug into their PC which turns it into a virtual radar picking up the transponder signals from all aircraft within line of site. This signal gives, amongst other things, the aircraft altitude, so it is possible to see exactly what height they are flying over your house. Cost ?379.95.
