Zurich Airport's noise charge model stipulates that every aircraft be classified in one of five noise categories based on noise measurements. The noise charge model for jet aircraft is based on average peak noise values during take-off, as measured at specific monitoring stations at Zurich Airport.
Noise class I comprises the noisiest and noise class V the least noisy aircraft types. The noise charge increases with each noise class and ranges from CHF 0 (noise class V) to CHF 2'000 (noise class I).
Night-time noise charges
During the night between 22:00 and 06:00, additional night-time noise charges are levied, which increase in half-hourly increments. Since 2013, flights between 06:00 and 07:00 and between 21:00 and 22:00 have also had to pay a noise charge supplement.
