Extensive efforts to reduce aviation noise

Aviation noise occurs, for instance, when aircraft take off and land − a situation that is hard to avoid. But major efforts are under way to reduce noise as much as possible. Examples of this are green approaches, adjustments in flight paths and that airlines pay lower charges when they use quieter aircraft.

Ground noise is loudest during take-off because the aircraft engines are operating at full throttle. Landings do not require full throttle but still generate high noise levels on the ground during the final stage of the approach, since this occurs at low altitude. Stockholm Arlanda Airport is working in various ways to reduce aircraft noise and to ensure that the fewest possible people are disturbed.

Lower charges for less noisy aircraft

Extensive international efforts are under way to reduce aviation noise. For example, the noisiest aircraft are no longer allowed to serve airports in the European Union. As a result, airlines have replaced their noisiest aircraft or changed engines.

At Stockholm Arlanda it is also less costly for airlines to take off in modern, quieter types of aircraft than in older, noisier ones. Sweden (an EU member) and Switzerland (which is outside the EU) were the first countries in the world to introduce this, but the other countries of the EU are expected to follow suit.

Stenvändarprocessen - a process to reduce noise

Stockholm Arlanda also works with Stenvändarprocessen (Swedish for “the stone turning process”) – an extensive project in which the airport is “turning every stone” to find new ways of reducing noise disturbances from air traffic. Green approaches and curved flight paths are examples of such measures. 

Open dialogue and heightened environmental awareness

In addition to measures aimed at limiting noise, the airport also carries out measurements and test flights as well as programmes aimed at helping air traffic controllers and pilots further increase their environmental awareness. An open dialogue with Stockholm Arlanda’s neighbours is another important element of the process. The airport endeavours to locate its flight paths where the noise will cause the least disturbance to the fewest people possible. The homes most heavily exposed to noise are noise-proofed.
