<<In the continuing furore re the extra runway little or nothing has been said about the effect on the Air Traffic System. Why is this ?>>
Heathrow used to have more than two runways and everything worked fine - landing on 23 and 27R and departing on 27L. Didn't cause any ATC problems.

Theoretically you could get 16 Heavies down in 30 mins with a few minutes to spare.
Applying 4nm spacing generally gets a landing rate of 36-37 per hour.
TBS aims to get 90s between Heavies.
Adding A380s would lower the landing rate, but ideally you'd bunch them together as there's no wake requirement between A380s. You could even get to a stage where the overall landing rate would go up because of that.

In fact it looks like 17 in 30 minutes has been achieved on at least one occasion in recent years, though sadly too long ago to replay on WebTrak.

At some point the government are going to have to make a decision on where extra runways are going to have to be laid, and how many. The general public will not get any say in the final decisions, and the subsequent routes are going to take a politician or two to just say "suck it up" to those affected by the new routes. Some things cannot be avoided.

A lump of Tarmac placed where there were once fields, houses, schools, offices etc. is not a runway. It only becomes one once it is hooked up to a passenger or cargo handling facility. Unfortunately for LHR, this is the bit our ignorant politicians fail to realise. It's is but like me saying I have a gold and diamond mine in my back garden. Well I do; if you dig far enough. The thing that has not been discussed is how this marvellous lump of Tarmac will be used. Will aircraft have to cross two runways get to/from to it? Will there be enough stands to handle the extra traffic? It's a bit like buying aircraft carriers without aircraft. Until the planes arrive, it's no more than a boat.
Regarding the ATC and ground handling I truly believe there will be no problem. Every hour that LHR is open, a really excellent team of people ensure that it is operating at maximum capacity. And if they are given a third runway, they will make it work. But to get the full benefit, the operational bugs should be ironed out before anything is built. But they won't be. I have no doubt that lots of expensive children in sharp suits will be called in to provide advice and design the thing only to p!ss off smartish when their fees are paid. Their true lack of knowledge will again become apparent when the real expects have to work with their design.
Best of luck Heathrow. You may eventually get your new runway. Your real problems will start once it is finished.

It is more that just a piece of 'Tarmac'. Please research before you post.

The following half-hour brings up a few more examples, including one that's recent enough to be viewable on WebTrak - 17th January this year, where 17 heavies landed on 09L between 0601L and 0630 in the following sequence:
B763-B772-B772-A388-B744-B772-B744-B744-B789-B772-A388-B744-B744-B77W-B788-A388-B763

DR,
Bear in mind that in-between those would have been arrivals to 09R (I assume - haven't checked). Using only one runway would increase the landing rate to that one runway.
