Source: Federal Ministry for Economic Affairs and Energy To improve the compatibility of air traffic control and wind energy, the Federal Ministry for Digital Affairs and Transport (BMDV), the Federal Supervisory Office for Air Traffic Control (BAF) and DFS Deutsche Flugsicherung GmbH have launched extensive measures in recent months. The common goal was to ensure the trouble-free operation of air traffic control systems while taking energy policy issues into account as far as possible in order to ultimately make more land available for wind on land. Essential aspects were developed by the Physikalisch-Technische-Bundesanstalt (PTB) as part of the research project WERAN (interaction of wind turbines and radar/navigation) funded by the Federal Ministry for Economic Affairs and Climate Protection (BMWK). At the same time, the measures now taken by air traffic control implement important parts of the key points of April 5, 2022, which the Federal Ministry of Transport and the Federal Ministry of Economics had agreed on. Volker Wissing: “Wind power is of great importance for a climate-friendly energy supply in our country. In order to be able to expand more quickly, we have made it possible to reduce the distance between wind turbines and air traffic control and meteorological systems on the basis of the latest scientific findings. We have thus removed a significant obstacle to the expansion of onshore wind power. I would like to thank everyone involved who, with great commitment and constructive exchange, reconciled the different requirements. Robert Habeck: “More areas for wind energy with the same reliability of radio navigation: That is a giant step and crucial for the expansion of wind power. The successful cooperation with the air traffic authorities and the Ministry of Transport is a very good example of how we are removing obstacles at all levels in order to accelerate the expansion of renewable energies to check the protection areas of air traffic control systems using the new scientific knowledge gained in the WERAN project. On the basis of new criteria, DFS now has the opportunity to re-evaluate the installation protection areas of the Doppler rotary radio beacons (DVOR) and to determine whether these can be reduced to the radius of seven kilometers proposed by PTB. Air traffic control aspects only have to be taken into account in construction projects within this radius. This reassessment will begin on August 1, 2022 and is expected to be completed by the end of 2022. The results already available allow the system protection areas of the DVOR Klasdorf, DVOR Gedern and DVOR Fulda to be reduced as early as August 1, 2022. DFS expects that the reduction can take place in many other cases and that one of the obstacles to the planning of wind turbines will thus no longer apply. New calculation formula for CVORThe possible disturbance of the navigation information provided by the radio beacon by wind turbines, the so-called angle error, is determined using a calculation formula. DFS and PTB were able to develop a new formula that enables more precise predictions. For the more robust Doppler rotary radio beacons, a jointly developed formula has also been used since 2020, since then the approval rate has increased to over 90 percent. With the new CVOR calculation formula, which is expected to be operational from the end of September 2022, a higher approval rate is also foreseeable for radio beacons of conventional design (CVOR). Acceptance of higher angle errors By reassessing the performance requirements required for area navigation on the one hand and technical modifications to the navigation systems on the other hand, a higher angle error caused by wind turbines, for example, can now be accepted and thus the available error budget increased from the current 1.0° – depending on the type of system – 1.5° or 2.1° can be more than doubled in some cases. This allows the construction of additional wind turbines in the system protection areas of rotary radio beacons. Dismantling and conversion of rotary radio beacons In the course of the introduction of modern, increasingly satellite-supported navigation methods, DFS is currently reviewing around 2,600 flight procedures in the entire German airspace. The new procedures enable radio beacons to be dismantled in many places. 17 plants have already been dismantled since 2002; of the 51 systems currently owned by DFS, a further 20 systems are expected to be dismantled by 2032. In addition, support from the BMWK made it possible to convert eight CVORs into less fault-prone DVORs.

DFS ensures safe and punctual flight operations. In peak years, around 2,200 air traffic controllers managed more than three million flights through German airspace, up to 10,000 a day. The company operates control centers in Bremen, Karlsruhe, Langen and Munich as well as towers at the 15 international airports in Germany. The subsidiary DFS Aviation Services GmbH markets air traffic control-related products and services and is responsible for air traffic control at nine German regional airports as well as at London-Gatwick and Edinburgh airports. DFS is working significantly on the integration of drones into air traffic and has founded the joint venture Droniq GmbH with Deutsche Telekom. The subsidiary R. Eisenschmidt GmbH sells publications and products for general aviation, Kaufbeuren ATM Training (KAT) trains military air traffic control personnel, and the joint venture FCS Flight Calibration Services offers flight calibration services. www.dfs.de
