Abstract The optimization of terminal airspace can provide more airport capacity to meet the growing aviation demand. Improving flight procedures is an important prerequisite for optimizing airspace. The existing air-route network visualization cannot fully meet the assessment needs of the terminal flight procedure. In this research, we introduce an analysis tool, VEFP, that provides multiple visualizations based on unlabeled flight trajectory data. The system can help domain experts to evaluate the terminal flight procedure from multiple perspectives, respectively. First, we provide a time series-based statistical information view to help determine the usage status of the flight procedure per unit time. Second, we evaluated the controller’s use of space for flight procedures based on the location information in the data. Third, combined with the visualization method after data processing, the visual complexity is reduced and necessary details are displayed. Then, the users can directly observe the actual flight procedure. We evaluate flight procedures in actual use through cases and experiments and then discuss with users about the observations provided by the system. These results confirm that our system can help domain experts evaluate flight procedures.

1 Introduction The study of flight procedure evaluation is very important for airspace planning researchers, as analysis of flight procedure will affect their optimized strategies. Some traditional aviation visualization work tends to describe the density and connection of airports. These studies often combined clustering algorithms and density estimation methods, and the results are usually shown as networks or nodes, which can help users estimate the air traffic flow between two airports [23]. However, for aviation experts, flight procedure assessment will focus more on how air controllers use flight

procedures to maximize the use of airspace, which is not the focus of route visualization research [33]. The data commonly used in related visualization research are aircraft data, which usually include position, altitude, heading, and speed. Existing researches usually focus on simplification of similar attributes and data compression. These systems are useful for network experts, while they may not be suitable for airspace planning and flight procedures evaluation [43]. We cannot predict which flight p
