→ 58 | Flughafen Berlin Brandenburg GmbH Aircraft noise measurement Transparency for the neighbouring residents Airports are obligated by the legislator to operate measuring points on the airport and in its surrounding area for the documentation of the aircraft noise. Flughafen Berlin Brandenburg GmbH has for this purpose in the surrounding area of Schönefeld and Tegel Airports have installed a total of 30 stationary measuring points (status 31 December 2017). The measuring results are transmitted monthly to the responsible authorities and the flight noise commissions and are published in the internet. Stationary measurements The locations for the stationary measuring points for the documentation of the The FBB mobile measuring device in Etzin aircraft noise are stipulated by consultation with the aircraft noise commissions, in which the neighbouring municipalities are represented. Measuring points are principally placed along the arrival and departure routes and in individual localities, which are affected by aircraft noise. With the selection of the locations other sources of noise such as main traffic roads or railway lines are avoided as these lead to a falsification of the results. In 2017 in the surrounding area of Schönefeld Airport five new measuring points were erected (Rotberg, Jühnsdorf, Schulzendorf/ Ernst-Thälmann Straße, Roter Dudel and Birkholz). The measurement data are called once a day from the measuring points and allocated to the flight movements based on the radar data of the German Air Traffic Control Services. Noise events, which were caused by other sources of noise than the air traffic, are determined subsequently and removed from the statistics. In addition weather data are used in order to avoid a falsification of the measuring results. By this form of aircraft noise monitoring FBB is in the position to provide information about the noise emissions of each flight movement and to reliably and continuously document the development of the aircraft noise situation. The data are in particular used for the calculation of the noise-related take-off and landing fees as well as for the processing of complaints. Mobile measurements At alternating locations FBB carries out mobile measurements, with which the aircraft noise events are as a rule recorded over one month. The noise measurement technology of the mobile systems corresponds with the requirements of stationary measuring points. The measurement mobile vehicle is used at the request of the aircraft noise commissions or the municipal authorities or at the request of the neighbouring residents. By repeated measurements at the same locations FBB documents the change in the aircraft noise burden over a longer period of time. With the stipulation of flight routes multiple measurements with the mobile measuring point also document the changes.

Environment | 59 ← Southern runway operation Schönefeld In order to record the noise burden during the southern runway operation in Schönefeld mobile measurements were carried out in 2017 at the locations Eichwalde, Gosen, Erkner-South, Grünheide, Groß Schulzendorf, Wietstock and Ludwigsfelde-South. As in the previous years the aircraft noise mobile device was used in Pankow in July. Owing to work on the northern runway the southern runway of BER was used from 16 July until 28 October at Schönefeld Airport. As the southern runway is located at a distance of 1,900 metres to the northern runway, there were changes to the burden and relief zones of various sectors in the area near the airport Schönefeld with regard to the aircraft noise. During the period of time of the southern runway use with the exception of the starts in direction east the flight routes of the BER were used already. The flight routes in direction east were guided by a swing to the left directly to the start on the existing flight routes of the northern runway so that the routes were flown as before from Karolinenhof. The flight routes of both runways and the calculated difference of the aircraft noise burden (permanent noise level) are separated for both operating directions presented in the lower maps. The isophones are presented hereby in differences of 5dB, whereby the area of -5 to 5 dB does not have any colouring. Aircraft noise with the southern runway operation Southern runway operation: Changed aircraft noise burden with the flight direction east. The difference of the calculated permanent noise level during the day is presented. Southern runway operation: Changed aircraft noise with flight direction west. The difference of the calculated permanent noise level during the day is presented. 5 dB
