Use noise-related fees reasonable
“Noise-related charges became established in Germany as early as the 1970s. The corresponding noise-related surcharges are intended to give airlines an incentive to use aircraft that are as quiet as possible. The principle is straight-forward: the louder the model of aircraft, the higher the charges the airline has to pay. This is intended to provide some relief from aircraft noise for the residents living near airports. Our airports are worldwide pioneers in this field.
