This morning was very noisy and woke me up at 6.15am so i got a screenshot of the problem
There were about three planes in a row, about 3 minutes apart making the same manoeuvre - decending from 6k ft to 4k ft while turning overhead from an approach from Thornton Heath to a heading towards Heathrow (they were flying toward the north north east and rotated round to west north west). This was really quite noisy despite having windows closed - not just noisy but across a range of frequencies from low to high due to the desceleration descent amd turn all happening simultaneously and surrounding the area.
There is a massive difference betweem the noise of these planes and the usual hum of planes flying in straight paths at 6k ft (which make less noise for me than motor bikes on the south circular - some distance away).
Anyway, just wanted to record that here as it was a particularly noisy. I’m not sure if there was a particular reason today (lots of tourists coming home creating a large stack, timing and position of surise creating a sharper turning circle, clear atmospheric conditions preventing any dampening, etc) but it is tough for those of us living above 300ft!
