Impact of Uncertainty on the Prediction of Airspace Complexity of Congested Sectors

Trajectory errors and unexpected aircraft can influence the prediction of dynamic density, which, in turn, is used as an estimate for controller workload. Air traffic controllers are responsible for keeping aircraft separated within the region of airspace, called a sector, which is under their control. The sectors are designed to enable controllers to handle the amount and flow of traffic. Consequently, the capacity of airspace is limited by the controller’s ability to perform tasks needed to maintain a safe system. The paper examines airspace complexity, dynamic density and simplified dynamic density, and forecasting complexity. The impact of an additional aircraft on complexity, including the impact of an unexpected popup aircraft, also is studied. If dynamic density is likely to be unacceptably high when unexpected aircraft appear, it may be necessary to limit traffic approaching the sector from certain altitudes and boundaries.
