German Environment Agency (UBA) awards “Flight progress data as a basis for aircraft noise calculations” three-year-project to GfL
October 2018 | Environment
GfL was recently contracted by German Environment Agency (UBA) to conduct the research project “Flight progress data as basis for aircraft noise calculations”. The project’s aim is to investigate to what extent flight progress data (e.g. Radar- and Multilateration Data) are suitable to achieve aircraft noise calculations with higher precision compared to today’s regulatory standard (AzB). Besides the raw data’s preparation for determining complete flight trajectories, the development of a quality-assured calculation method including individual parameters specific to flight performance (essentially flight altitude and speed, thrust and aircraft mass) is a particular focus. In this respect, the knowledge gained during the development of our in-house fuel and emission calculation software ETAS (further information see here) can well be used. Within the framework of this project, GfL is supported by TU Dresden’s Chair of Air Transport Technologies and Logistics (see here), as a consortium partner, especially dealing with flight meteorology and flight profile optimization. Furthermore, the acoustic experts of Wölfel Engineering GmbH + Co. KG are part of the project team, having excellent experience in the field of aircraft noise calculation. In addition, the German ANSP DFS is involved in the project to support with data. Within a project run time of three years, we aim to develop a calculation method which may amend and specify the standard calculation methods used in Germany to date (in accordance with the German Aircraft Noise Act or AzB and AzD) and adapt it to the current state of knowledge.
