New noise report indicates Heathrow’s noise footprint at smallest recorded levels

Heathrow airport’s noise footprint continues to shrink. The finding was reported by a new annual noise contour report that said 52,000 fewer households were affected by noise compared to 2006.

Independent analysis from the Civil Aviation Authority (CAA) authorized by Heathrow, indicates that the average noise contours continue to shrink. This analysis, which has been conducted on a regular basis since 2006, is part of the airport’s Noise Action Plan and a pledge to provide more regular and transparent communications to local residents.

This year, in response to requests from the community, Heathrow has included new metrics in the analysis that look at overflight track density diagrams and single mode contours, making this ‘super report’ the most all-inclusive noise contour report ever published by the airport.

The independent report demonstrates that over the past 11 years, the area around the airport impacted by average noise measurements over the course of a 24-hour operating day, as measured using the preferred European measure of noise (Lden 55 dAB), has gone down by 15%. This means 15% fewer households within the area are affected by noise. Had the population and households remained unmoving during this period, there would be 21% fewer homes affected by these noise levels.

This report is published at the same time as the updated quarterly ‘Fly Quiet and Green’ results, classifying the performance of 50 airlines on seven noise and emission metrics from July to September this year.

The latest results show the contest is intensifying as airlines enhance ‘track keeping’ – the ability to adhere to the Government-set departure noise preferential routes in the skies from Heathrow – and provide what the airport is now calling, their “greenest” aircraft to the UK hub.

The new league table places Air India fleet as the quietest flying to Heathrow from July to September, up a remarkable 41 places since the first league table ranking performance from January to March of this year.

The airline’s fleet at Heathrow is composed of almost exclusively of state-of-the-art, super-quiet Dreamliners. Oman Air’s performance has also substantially improved, after engagement with Heathrow’s noise team on how to augment their operations. Oman has achieved a 98% “track keeping” record, boosting their position 15 places since June this year.

‘Track keeping” winners also include China Southern, up a notable 17 places since June, and regional airline Flybe improving their position from 29th to 18th place.

Heathrow Sustainability Director Matt Gorman said:

“Heathrow has some of the world’s toughest rules and regulations on noise, which have played a major role in driving developments in quieter aircraft technology. Over the past 30 years, we have managed to more than double our passenger numbers whilst decreasing our noise footprint to its smallest levels yet – this is testament to the efforts of Heathrow and our airline and manufacturing partners to reduce the impact of the operations.

“While we mark significant progress today with more airlines changing their operations in response to the Fly Quiet and Green league table, we also know that we need to continue to develop how we communicate on noise. This new ‘super report’ contains a range of new metrics that will better inform the next Noise Action Plan and give our local community a clearer picture of noise patterns around the airport and the opportunities to reduce noise further still.”

Heathrow is also doing its part in improving technology by bolstering the amount the noisiest, oldest aircraft has to pay to land at the airport.

This year, the airport has doubled the tariff attached to nitrogen oxide (NOx) emissions. This means environmental landing fees for airlines have doubled this year – from £8.57 per kg of NOx emitted to £16.51 per kg – offering another incentive to use cleaner aircrafts. The noisiest planes will face a trebling in charges to £9,000 per landing.
