Can the airways be reduced?

The bandwidth in relation to the prescribed route (the ‘line on the map') can rise to a number of kilometres on both sides of the route. Depending on the wind and the runway combination used, variation can therefore arise in the flight pattern within an airway. The use of a bandwidth means that certain residential areas may experience more noise pollution at some times than at others. The airways can perhaps be made narrower in the future through the use of new navigation and landing systems. If this is the case, only after 2010, this will mean that certain residential areas will face more noise pollution, because the distribution of the noise will shrink.
