Abstract:

This report presents the latest results of research conducted at the Volpe Center on improving air traffic demand predictions and enhancing the Traffic Flow Management System (TFMS) Monitor/Alert function for identifying potential congestion at National Airspace System (NAS) elements such as airports, sectors and fixes. This report deals with uncertainty in traffic demand predictions in en route sectors and with the identification of potential congestion in airspace. Currently, the TFMS measures demand and determines alert status at each 15-minute interval of the time period of interest by comparing demand with the Monitor/Alert Parameter (MAP). However, unlike airports and fixes, where demand is determined by aggregating flights in 15-minute intervals, the TFMS predicts sector demands for each minute of a 15-minute interval and uses the demand of the peak minute as the sector demand for entire 15-minute interval. In other words, the entire 15-minute interval is alerted even if predicted demand exceeds the MAP only in one of fifteen minutes. Using the peak demand from a single minute to declare sector alerts for entire 15-minute interval creates some problems for and has been criticized by many Traffic Flow Management (TFM) and Air traffic Control (ATC) specialists mostly because of low accuracy and reliability of TFMS sector Monitor/Alert functionality.
