In recent years, civil drones have become more and more visible in everyday life. There are numerous reports in the media covering a variety of drone aspects and technical developments. In addition, everyone is used to bird's-eye views as common features in television, movies and photography. However, little is known about how the public perceives this development. This article reports the results of a representative national study on the acceptance of civilian drones. Overall, a balanced but slightly positive attitude towards civil drones was revealed. Factors analyzed include age, gender, place of residence or interest in technical matters, as well as the individual level of knowledge about the topic. Free verbal associations with the general term drone are described as well as concerns about the usage of civil drones. Concerning different applications of civil drones, results indicate clear approval in Germany for the use of drones in civil protection, rescue missions and research work. However, flights for advertising, leisure and parcel delivery purposes are disagreed with by at least half of those questioned. In the presentation of the results, this article describes social acceptance of civilian drones and thus helps to better understand the perception of civil unmanned aerial vehicles.

This paper focuses on the role which workload can play for work organisation in a future remote control tower center. Nowadays you can find a control tower next to each airport. A tower is equipped with a team of controllers which maintain the declared surface movement rate under all weather conditions within the aerodrome visibility operational level (AVOL) while maintaining the required level of safety. Novel concepts for air traffic control (ATC) consider remotely controlling regional airports from a control center that includes working positions for the control of multiple airports. When evaluating such controller working positions, workload is a crucial concept. A thorough analysis of workload in a remote tower domain is used in the paper at hand to draw conclusions for the work design of a remote control center. In a simulator study at the Institute of Flight Guidance of the German Aerospace Center a remote center working environment was realized for controlling two regional airports. In a 3-factor experimental design it was investigated empirically how workload ratings differed when (1) one controller was responsible for two airports; or when two controllers were responsible for two airports with (2) each controller responsible for one airport or rather (3) working in a team responsible for both airports. Workload ratings were gathered online using the Instantaneous Self-Assessment scale and after each simulation run using the NASA-Task Load Index. In addition, expert participants judged specific traffic situations in the single operator condition for two airports in respect to its operational feasibility. The data are analysed and discussed in respect to what can be learned for work organisation and future ATC concepts. This paper, thus, contributes to better understanding the basic conditions a controller needs to meet his obligations as an air traffic controller. Such knowledge is indispensable when developing novel concepts for remote control of regional airports. remote tower control, work organisation, workload, safety I.

The paper aims at understanding crucial variables that influence the control of visual attention of tower controllers. Novel concepts for aerodrome control of regional airports consider to remotely control two or more airports at a time from one remote center. A simulation experiment was set up where 12 professional tower controllers operated parallel traffic of two airports. Eye gaze recording and questionnaires were used. Two feedback loops are considered to influence the controllers monitoring behavior: The accessibility of the information of the "far-view" and controller strategies. The results show that both variables have a crucial influence on how often the controller updates the information of one airport. This implies that monitoring performance depends on system design and behavioral strategies. These dependencies can be applied to the design of novel ATC-workplaces.

New tools and algorithms for geological remote sensing are developed and verified at test sites throughout the world in preparation of the German hyperspectral satellite Mission (EnMAP), which is an Environmental Mapping and Analysis Program.The Aggeneys Cu-Pb-Zn deposit, situated in the arid north western part of South Africa, represents a unique field laboratory for testing these new tools. Here spaceborne hyperspectral data covering the Swartberg, SOUTH
