چکیده

Predicted growth in air traffic and the desire for more user preferred routes in the National Airspace System (NAS) will impose additional demand on air traffic control and management systems. This demand can be met by alternate airspace configurations, modified traffic patterns, and staff reassignment. There is a need to understand the effect of changing airspace configurations and traffic patterns on the workload of air traffic controllers. This complex relation is referred to as “Airspace Complexity”. Research on dynamic density indicates that it is a good measure of airspace complexity. Dynamic density is a function of the number of aircraft and their changing geometries in a given airspace. In order to use dynamic density as a planning tool, it is necessary to project its behavior over the planning horizon. The objective of this work is to study how well dynamic density can be predicted into the future using the trajectory generation feature of the Center-TRACON Automation System (CTAS). This paper describes the application of trajectory prediction to computation of actual and predicted dynamic density using traffic data from Dallas/Fort Worth airspace. Results show that dynamic density can be predicted up to 20 minutes in advance and errors in predictions can be further Raytheon ITSS reduced by accounting for departure traffic.

The prediction of airspace complexity is of great interest for Air Traffic Management (ATM). Airspace complexity based on traffic situation prediction affects short- and medium-term trajectory management strategies and also affects the capacity of Air Traffic Control (ATC)

The prediction of airspace complexity is of great interest for Air Traffic Management (ATM). Airspace complexity based on traffic situation prediction affects shortand medium-term trajectory management strategies and also affects the capacity of Air Traffic Control (ATC) operations. Our research group is developing a “difficulty index” of ATC to represent the degree of airspace complexity. The ...

Expanding the Use of Time-based Metering: Multi-center Traffic Management Advisor

Time-based metering is an efficient air traffic management alternative to the more common practice of distance-based metering (or “miles-in-trail spacing”). Despite having demonstrated significant operational benefit to airspace users and service providers, time-based metering is used in the United States for arrivals to just nine airports and is not used at all for non-arrival traffic flows. T...

Airspace configuration using air traffic complexity metrics

Flow regulation is a critical process in air traffic management, ensuring that the incoming traffic does not exceed the ability of air traffic controllers to handle it safely and efficiently. Currently, the european Flow Management Positions (FMP) use flight counts and sector capacities to assess the traffic load and build predicted opening schemes. These schemes, made of predefined airspace co...
