It is worth noting that London City Airport’s are consulting on their Draft Master Plan for 2020-2035. This document which out a framework for how flights from City Airport will be managed over the 15 year period and in the background is a fair amount of concern about the way this will increase the number of flights over south east London.
The site for the consultation is here: https://www.londoncityairport.com/corporate/consultation.
There is also an excellent overview in the newsletter from HACAN East which you can see here: HACAN East newsletter August 2019
There is a 12-week consultation period from 28th June to 20th September 2019 and if you are in any way concerned (residents do regularly contact me about aircraft noise early in the mornings – although a lot of this is from Heathrow) please do take the time to respond.
