The aircraft-specific noise data in the Instructions on the Calculation of Noise-Protection Areas (Anleitung zur Berechnung von Lärmschutzbereichen) from 2008 (AzB-08) were collected several years before the AzB-08 was published. In this aircraft noise calculation, newer aircraft types that have been commissioned since this time are treated the same acoustically as the older types with comparable capacity.
However, as some of the new types have far lower noise emission levels than their predecessors (Airbus A380, Boeing B787, A320neo, A350 and others), Fraport has carried out additional aircraft noise calculations since 2017 in which the movements of modern aircraft types are allocated to modified aircraft groups in line with noise emission data.
The method used for the calculation with noise reduction measures is the same as the method used in monitoring calculations for the noise emission ceiling. For details on this, see the monitoring report on the noise emission ceiling in 2017.
