Carbon emissions, Nox and particulates all down. No real surprise there I guess.

Watching https://www.flightradar24.com give you a good idea of how much has changed especially later in the day when flights to the USA normally take place.

That's only if you know how busy it should normally be...

Very true

As for how the real-time map should look, just think about the long term battle there has been to add an extra runway in the South East, until 2 weeks ago you would see planes flying in circles as they queued to land at Heathrow and Gatwick, now not so much.

I live under the south runway landing path for Heathrow and itís remarkably quiet and free from air traffic.  Likewise the A316.  Really dramatic falls in traffic volume, noise and therefore pollution.

And yet what is the Nat Grid doing still transmitting coal powered - i dont get it.  The gas is very well throttled back.  Does anybody really know why?

That would be my theory as well guessing that they have already used up their legal quota (12hr/yr i think) for a yr and cannot afford anorther one.  But i would like to hear it from the horses mouth.

Burning through their remaining coal stocks before they have to shut down for good?

Thanks for that, the graph shows that from 175 000 it's now running at 100 000 flights per day, so it hasn't even halved, which I find surprising.

It is time that the EU relaxed their use it or loose it rules for landing slots.  There are lots of empty planes flying around to keep slots valid.
Ok, perhaps with some freight.

They have already done it. New temporary rules came in earlier this month.
