The Most Overflown Boroughs in London

An Analysis by HACAN (2009)

 Hounslow is the most overflown borough in London.  Richmond is in second place.  But the big surprise is that Waltham Forest comes third.   Indeed half of the top twelve boroughs are in East or South East London.  In part, this is due to the impact being overflown by both Heathrow and City Airport aircraft.  It is also indicative of the way aircraft noise has become a London-wide problem.

Short Haul Flights: still clogging Heathrow’s runways

A new study from HACAN reveals that nine out the ten top destinations served by Heathrow are short haul. Only one, New York, is long haul.

The rest are European or British destinations. New York, with 61 flights a day, tops the table. It is followed by Dublin, Amsterdam, Frankfurt, Paris and Edinburgh. The study comes seven years after a similar one published by HACAN in 2006. That study placed Paris top of the league. However flights to the French capital have fallen dramatically since Eurostar has taken off – down from 60 a day to 35. And Brussels flights have decreased from 30 to 19.

Major New Night Flight’s Report finds night flight ban at Heathrow could benefit the economy

 A major report launched in the House of Commons on 27th January 2011 at a meeting hosted by Zac Goldsmith MP shows that a ban on night flights at Heathrow before 6am could be expected to have overall benefits for the wider economy.

The new report, commissioned by HACAN from the respected Dutch economists CE Delft, has found that a night flight ban before 6am could benefit the national economy by as much as £860 million over a 10 year period.

The big savings would be in the monetary costs associated with sleep deprivation. Because of the huge number of people living under the Heathrow night flight path, these savings could be expected to outweigh any loss of income to the aviation industry.

CE Delft argues that the national economy would only be harmed if none of the passengers who currently arrive on the flights before 6am failed to transfer to flights arriving at other times. If that were to take place, the national economy could lose up to £35 million over a 10 year period, but the report states that the chances of that happening are “highly unlikely”.

John Stewart, Chair of HACAN, said, “We commissioned this report to test out the claims that a night flight ban would damage the economy. Its dramatic findings destroy the last remaining argument for night flights”.

The launch of the report marks the start of a campaign by HACAN to get a ban on night flights between 11pm and 6am when the new night flight regime is introduced in 2014.

Later this year the Government is expected to consult on a new night flight regime at Heathrow, Stansted and Gatwick. The current agreement with the airlines comes to an end in October 2014.
