The Gatwick Airport campaign for a second runway states on that 'only 18,000 people would be additionally affected by noise if Gatwick built a new runway'. Do you agree with me that no additional people should be affected by noise resulting from any expansion, let alone 18,000 people?

I absolutely agree that we should seek to minimise the number of people exposed to aircraft noise. The research previously undertaken by my team suggested that following expansion at Gatwick, around 780,000 people would be exposed to aircraft noise across London and the South East (at 55dB Lden - the standard EU aviation noise metric). Following expansion at Heathrow there would be 1,140,000 people exposed to aircraft noise. The analysis showed that only by relocating the hub from Heathrow to a new location to the east, away from densely populated areas, could we make a significant reduction in the number of people exposed to aircraft noise across the London and the South East - falling to 75,000, less than 10per cent of those exposed today.

It was disappointing that the Airports Commission ignored such data in choosing not to shortlist the options for a new hub to the east of London. Nonetheless, it will be for Government to decide on the best approach, having evaluated all the evidence available.
