Data underlying the publication: Contributing Factors to Flight-Centric Complexity in En-Route Air Traffic Control

This dataset accompanies the article "Contributing Factors to Flight-Centric Complexity in En-Route Air Traffic Control". It includes the characteristics of a flight with respect to a scenario's flight of interest and the number of professional air traffic controllers that included this flight when asked whether it added to the perceived complexity of the flight of interest. This data was used for training and evaluating the flight-inclusion machine-learning model discussed in the article.
