Eline Bakker (TUD) – Design and Evaluation of a Visual Interface for an En-Route Air Traffic Control Merging Task
In the past decades, the air traffic growth has resulted in increasingly complex situations involving more aircraft simultaneously. In order to guarantee safety is maintained within the increasingly crowded airspace, new solutions are expected. In collaboration with the LVNL, an Inbound Traffic Support System interface was developed. The goal of the interface is to visualize the possible solutions of an area controller’s task of merging aircraft towards a restricted waypoint in the current work domain, such that the impact of decisions made can be foreseen. By showing the affordances of the work domain, the display keeps the air traffic controller as the active decision maker rather than issuing advisories.
Matthijs Ottenhof (TUD) –Wind and Trajectory Uncertainty in a 4D Trajectory Management Interface
With air traffic numbers increasing, a shift in the Air Traffic Management system towards 4D flight plans, where an aircraft trajectory is pre-planned in both time and space, is foreseen. When these pre-planned trajectories are subsequently executed, unforeseen airspace perturbations, such as weather, sequencing and changing airspace constraints, will inevitably require small changes in the trajectories to be made by the air traffic controller. This perturbation management control task will consist of ensuring a safe airspace while adhering to the strict time constraints imposed by the 4D flight plan. In collaboration with LVNL, a decision support interface was designed and evaluated with the aim of visualizing possible conflict resolutions in the 4D domain. A special focus was put on the integration of wind and trajectory uncertainty information into the interface.
