Thoughts from the think tanks
A couple of think tanks (Policy Exchange and Centre Forum) have got their heads together to produce a thoughtful and thought-provoking analysis of possible solutions to aviation capacity in the south-east.
The best approach would be to build a new four runway Heathrow, immediately west of the current site. These new runways would replace the existing runways. This would be straightforward to construct, and relatively low cost by the standards of hub airports. A combination of tightening permitted noise classes, ending night flights and landing narrow bodied planes more steeply makes it almost certain that this airport would be significantly quieter than the existing airport, despite catering for almost twice as many flights.
Leaving the airport where it is works for air traffic control. It also works for the wider economy: companies that have located near to the airport because they need to be near the airport do not have to move. The design of airport proposed here would be operationally efficient for both passengers and airlines, and would be the world’s best hub.
