The challenge of this application to stage technology is the absolute security of people in the interplay with technology. In the present case, this concerns the safe flight of the bird of Helene Fischer and its precise landing on the small platform midst the audience. Due to the 80 metres long and winding guide rails no trailing cable connection to the bird was possible here. Power supply was therefore via an additional bus bar, at which power electronics was ridden along as well. On the other hand, control commands to this moved system had to be transmitted wirelessly, i.e. radio, a particular challenge in view of the operational safety required.
