The EuroAirport Basel-Mulhouse-Freiburg is located in the triangle formed by Germany, France, and Switzerland. Thanks to this “tri-national” position, the airport plays a unique role in the international traffic infrastructure. With over 9 million passengers, almost 100,000 flight movements, and 100,000 tons of freight in 2019, they set a record for traffic levels before the start of the coronavirus pandemic. After an over 70% reduction in passenger numbers in 2020, the number of flight movements has been increasing again slowly since 2021.
The airport has operated a Topsonic aircraft noise measurement system for many years, including fixed and mobile noise measurement stations at the airport and in surrounding communities. The airport has significantly expanded its publication of aircraft noise data as the result of their own noise prevention plan PPBE, and at the request of the neighborhood associations and based on a recommendation of the French controlling authority ACNUSA (Autorité de Contrôle des Nuisances Aéroportuaires). Topsonic delivered the multi-lingual “WebReporting” online portal as part of open and transparent monitoring of flight operations. The portal displays reports and statistics from the different work areas of the environmental department. In addition to commonly used aircraft noise measurements, it also publishes information on the number of complaints received, and special night flights.
The Topsonic application “TraVis” also displays flight plan and weather data, airplane types, rising and lowering profiles of the planes and level diagrams for the individual measuring stations. Questions and specific aircraft noise complaints can be correlated directly with a flight movement and submitted via an input dialog.
