Use of on-demand night-time marking (ONM) will become mandatory for many wind turbine operators on 01.07.2021. According to the General Administrative Rules for the Identification of Aircraft Obstructions (German: Allgemeine Verwaltungsvorschrift zur Kennzeichnung von Luftfahrthindernissen, AVV), in principle, ONM retrofitting can be carried out using radar systems or by means of a device that uses transponder signals. In cooperation with partners, Deutsche Windtechnik has developed a universal, independent ONM solution, which can be used by all operators to retrofit their turbines to comply with the AVV: The BNK-BOX Deutsche Windtechnik.
The Deutsche Windtechnik ONM system including the BNK-BOX, is characterised by great flexibility and versatility:
In addition, it is designed for reliable documentation and ONM operations management. The BNK-BOX from Deutsche Windtechnik comprises a separate control unit that is installed right by the hazard lighting in the nacelle itself. When signals from approaching aircraft are detected, the system uses robust algorithms to check them, and the hazard lighting is activated. If a defect occurs in the control system unexpectedly, night-time marking is activated automatically (failsafe activation). Before the system is connected, the wind turbine locations and the technology of the existing night-time marking system must be checked.
