The discussion on the 3th runway in Heatrow will include the banning of night flights and legal implications of ever considering the building a fourth runway.

The Airports Commission has recommended A third runway should be built at Heathrow, but only if it can meet stringent conditions on noise and air pollution.

Those conditions should include a ban on night flights, legally binding caps on noise and air quality – and legislation to rule out ever building a fourth runway.

There had been speculation that the commission would hold the door open for Gatwick. But the
commission said on Wednesday morning it was “clear and unanimous” Heathrow’s plan was the strongest case for future airport capacity, delivering the greatest strategic and economic benefits, and the conditions would make the airport a “better neighbour” than today.

The £17bn expansion plan would mean 250,000 more flights a year, providing a £150bn boost to GDP over 60 years and 70,000 new jobs – but would mean demolishing 783 homes, including most of the neighbouring village of Harmondsworth.

The long-awaited verdict comes five years after the government cancelled plans for a new runway at Britain’s biggest airport and is expected to spark a renewed political battle.

Sir Howard Davies, the commission chair, said the government would need to review the analysis carefully before making a decision. But he warned it to “move as quickly as it can” or be seen as unwilling to “take the steps needed to maintain [Britain’s] position as a well-connected open trading economy”.
