You are the one that is simple. There are quite a few built up areas
in the South East even if you want to ignore London.

But none sufficiently close to the airport to be bothered by the noise
on takeoff.

Then there is the question of what happens when the winds are easterly.

The sound doesn't blow that far (and the takeoffs will be across the
north sea).

That sort of depends on destination - I can't see a lot of demand for
0300 departures to many places, nor really arrivals at that sort of
time.


There is huge demand for cheap charter flights to/from Gatwick, and
they take off and land throughout the day and night. In summer, the
airport is almost at busy at night as in the day.

That'll be for people living really close.

Increased wind strength also seems to have a distinct effect WRT to
flattening and straightening out the incoming flight path and thus
shaking a few more roofs.

But the approaches won't be.

Indeed. They'll be turning onto the runway from east of London.

Maybe. Approach tracks are generally longer than take-off tracks the
glide slope being much flatter.

Why should that be a worry? If you compare the noise created by an
airport now to that say 20-25 years ago then they are almost silent
and getting even more quiet year on year.

But for the vast majority of the approach the engines are on idle and
thus significantly less noisy than on departure.
