While there has been significant research in the development of visualization tools for users of technology, little attention has been paid to developing visualization tools for human factors researchers designing experiments. From a design of experiments perspective, it is difficult to design video game-like experiments like those in found in air traffic control research, because of the need to control potential confounds such as consistency of scenarios and possible practice effects. When designing scenarios, the state and consistency of initial conditions can critically affect the experiment's outcome and validity. In this paper, we discuss several tools and techniques that were developed to better visualize these initial conditions and easily export them to the interface software. The key features of these tools are that they are relatively simple to develop, straightforward and fast to use, provide a graphical interface for the experiment designer, and ultimately can reduce the total design time for each experiment. Visualization tools based on the same general principles can also be of value in other domains.

Abstract. The paper examines the workload perceived by air traffic control officers (ATCOs) and pilots during continuous descent operations (CDOs), applying closed- and open-path procedures. CDOs reduce fuel consumption and noise emissions. Therefore, they are supported by airports as well as airlines. However, their use often depends on pilots asking for CDOs and controllers giving approval and directions. An adapted NASA Total Load Index (TLX) was used to measure the workload perception of ATCOs and pilots when applying CDOs at selected European airports. The main finding is that ATCOs’ workload increased when giving both closed- and open-path CDOs, which may have a negative impact on their willingness to apply CDOs. The main problem reported by pilots was insufficient distance-to-go information provided by ATCOs. The workload change is important when considering the use of CDOs.

Abstract. Owing to the different approaches for remote tower operation, a standardized set of indicators is needed to evaluate the technical implementations at a task performance level. One of the most influential factors for air traffic control is weather. This article describes the influence of weather metrics on remote tower operations and how to validate them against each other. Weather metrics are essential to the evaluation of different remote controller working positions. Therefore, weather metrics were identified as part of a validation at the Erfurt-Weimar Airport. Air traffic control officers observed weather events at the tower control working position and the remote control working position. The eight participating air traffic control officers answered time-synchronized questionnaires at both workplaces. The questionnaires addressed operationally relevant weather events in the aerodrome. The validation experiment targeted the air traffic control officer’s ability to categorize and judge the same weather event at different workplaces. The results show the potential of standardized indicators for the evaluation of performance and the importance of weather metrics in relation to other evaluation metrics.
