ABSTRACT
The Detailed Policy Assessment Tool (DPAT) models the propagation of delay throughout a system of airports and sectors. We present a DPAT analysis to show the effects of simulated changes in capacity due to inclement weather. Local delays are dependent on the capacity to demand ratio of departures and arrivals. We show propagated effects are significant for the 1st leg after leaving an airport affected by reduced capacities and diminish from leg to leg.
