All have now made their opinions quite clear & these will not change.However all the words here will not eliminate the basic problem that clearly exists on the ground at SEN & generally around other airports.
It is quite evident that some airport operators whilst going for maximum growth have tougher regimes in place to mitigate impacts on populations than others.
The regimes imposed are sometimes national for instance the DFT strictly control noise generation at the three LON majors of LHR/LGW & STN.
Whether due to history (the growth of Council controlled airports not anticipated back in the day) or other factors is unclear.What is clear is that Council controlled dromes are it appears "pushing it" & perhaps posters should be more careful what they wish for when only hoping their Airbus to the sun will be filled rather than contemplate consequences for your neighbours.
Some airports have arrived at their own mitigation decisions too by acknowledging that they have to be good neighbours to achieve the growth & have put many such measures into place voluntarily.
Now even more so with all manner of lobbyists growing stronger by the day (the chief spokesperson for the Extinction Rebellion with airtime on BBC wants to end flying in five years time! extreme I realize) but even so warnings are there.
Frankly SEN it seems has to start showing some empathy & mindfulness towards local populations & engage certainly with the chequebook.
Quick note for Expressflight...I admire your debating posts but perhaps trying too hard now.To suggest an Airbus/Boeing even at "idle" is of no magnitude reflects no credit on the poster.
Have you actually listened to the video that has played around the world.
