We’re very aware of the impact aircraft noise has on those who live under flight paths. That’s why we work with airports and airlines to help them minimise the effect of noise and provide respite in the vicinity of the airport.
New, quieter engines and smarter procedures are helping, and Sustainable Aviation’s recently published Noise Road Map sets out how traffic levels can continue to grow to 2050, without any increase in noise.
Noise Respite Trial at Heathrow
But there are also practical things that we can be doing now. Last year we started a trial at Heathrow designed to provide defined periods of noise respite to people living directly under the flight path. The concept was formed in partnership with the noise community group HACAN, BA and the airport itself.
On average, around 16-17 flights arrive at Heathrow each morning between 4.30am and 6.00am. The trial explored whether routeing these flights in a more defined way – particularly at the beginning of their approach into Heathrow – could offer more predictability for the people living below.
The trial, which began in November 2012, had defined zones in the approach area above London and over Berkshire that were ‘active’ sequentially week by week. Pilots were directed by our controllers to avoid flying through the zone that was active for that particular week.
Inner and outer quiet zones were established for each of the two runways which resulted in eight zones in total (four over West London and four above Berkshire for east/west operations). The active areas appeared as shaded boxes on controllers’ displays which were to be avoided unless in exceptional conditions or for safety reasons, for example, in the event of low visibility.
Trial now complete, results in the Autumn
The trial, which completed at the end of March, is a good example of the importance of air traffic management in tackling noise. The results, including community responses, will be available in the autumn. We’re looking forward to seeing the results and understanding better how we can shape air traffic management to tackle the issue of noise.
