→ 44 | Flughafen Berlin Brandenburg GmbH Avoiding noise The Aviation Industry is tackling it Air traffic is growing and is developing in a particularly dynamic manner at the Berlin location. Despite the enormous growth in passengers the aircraft noise in Schönefeld and Tegel has approximately remained constant or only increased moderately on average in the past few years. This is possible, because aircraft and engine manufacturers, airlines, airports and the German Air Traffic Control Authorities with the decisive participation of science have developed technologies and processes in order to make flying quieter. The use and further development of low-noise technologies and flying processes are central pre-requisites in order to secure the acceptance of aviation in Berlin and Brandenburg in the long-term. Modern air traffic allows people in the region of the capital city to reach a lot of destinations in Europe and numerous destinations worldwide directly and connects companies and their products with the global economy. With 45 million overnight stays in 2016 Berlin, Potsdam and Brandenburg are an attractive tourist region. Society’s need for mobility must however be brought into line with the need for quiet and protection of the neighbouring residents in the environs of Schönefeld and Tegel Airports. FBB ensures this by a comprehensive noise protection programme, the levying of take-off and landing fees depending on the noise and the avoidance of unnecessary ground noise. It is particularly effective to minimise noise at the source. The airlines are continuously investing in new aircraft technologies and modernising their fleets. Modern aircraft have substantially quieter engines. Industry and science are working at reducing the sources of noise on the aircraft surface, on the wings and on the landing gear. By 2020 already aircraft of the newest generation will only be perceived half as loud as aircraft put into service at the turn of the century.

This level among other takes into consideration corrections for tonal shares and is not comparable with the A-assessed noise level.

Environment | 45 ← Quieter, cleaner, larger Quieter aircraft are reaching Berlin With the A380 Airbus succeeded in constructing a modern wide-body aircraft in 2006, which is considerably quieter than comparable aeroplane types. In the segment of the narrowbody aircraft with only one middle aisle used at the Berlin airports to a large extent a further development was, on the other hand, not carried out in the last 15 years. Airbus now also has improved aircraft on offer in this segment. The A320neo (New Engine Option) was thus developed and delivered to Lufthansa as the first customer in 2016. With another engine configuration (CFM International LEAP) the Turkish Pegasus Airline is also increasingly flying to the Schönefeld Airport with the A320neo. FBB has evaluated the measurement data of the A320neo flights of Pegasus in 2016 and hereby on average at the individual measuring stations assessed a substantial reduction in noise by 4,5 dB. Based on these data a so-called “noise footprint” (maximum level of > 70 dB(A) of a take-off) of both variants of the A320 could be presented on the map. The polluted area is halved. Noise-sensitive area is disappearing Comparison of the area > 70 dB A320/A320neo Legend A320 A320neo
