| Abstract | The Traffic Flow Management System (TFMS) currently declares an alert for any 15-minute interval in which the predicted demand exceeds the Monitor/Alert Parameter (MAP) for any airport, sector, or fix. For a sector, TFMS predicts the demand for each minute, and TFMS uses the demand of the peak minute in a 15-minute interval to decide whether to declare an alert for the entire 15-minute interval. Using the peak demand from a single minute to declare alerts has been criticized for three reasons. First, the demand from a single minute is a flawed measure of workload for the entire 15-minute interval. Second, using demand for a single minute leads to instability; that is, slight fluctuations in demand from minute to minute can lead to alerts flickering on and off. Third, the interval that is alerted depends on the arbitrary, 15-minute boundaries. |
