Discussion continued from Aircraft Noise over SE23 
Fine weather again, don’t forget to keep logging complaints with London City. Here’s mine from today.
Once again I find it necessary to complain about the low altitude aircraft flying today over Forest Hill to LCY. They fly under 2000 feet, which is too low, create persistent repeated noise at around 60 db and interrupt greatly the enjoyment of the outdoors. Inevitably this happens during the fine weather that accompanies east winds in this area. I am also dismayed to see that LCY has applied to the CAA to put back by nearly a year the CP1616 process. This appears to demonstrate the lack of any urgency or concern by the airport for overflown residents, despite three years of record complaints and detailed representations to the airport by residents including from the Forest Hill Society following the introduction of concentrated low altitude flight paths over SE London.
London City are going through an Airspace Change process. They have applied to the CAA put back the process ’ in order to deconflict the engagement process with previously planned airport activity’. I would think this means their expected expansion plans in the forthcoming Masterplan, which they are prioritising ahead of addressing noise relief and flight paths.
Meanwhile here is a way we can all help to quantity the aircraft noise in our or any area, using a new app developed in Holland. Download Explane on to your smartphone, then simply point the phone mic at a noisy aircraft. It logs the noisiest 10 seconds, identifies the plane and you can then submit the data to their central database. The crowdsourced data is then analysed, shared and can be used to provide evidence of the need for change. This is so new that no one is using it for London City planes yet. I started today. Could a few of us start to build an evidence base that we can use to create more pressure for change? Anyone else care to try it and report back?
