Abstract : This report describes a case study to show the benefits from maximum utilization of existing air traffic databases. The study demonstrates the utility of integrating available data through developing and demonstrating a methodology addressing the issue of airport performance. The study utilized data bases which addressed the factors of airport capacity and aircraft delay, and focused on the single airport of Philadelphia International. Since avoidable delays impose major costs to the nation's airlines, the study objective was to better understand the conditions under which delays occur and their causal factors. This will provide guidance for decisions on airport investments which are justified with well-defined benefits. The report presents quantitative measures of average delay, number of delayed flights, and total delay. As expected, there were more delayed flights and longer average delays under poor weather conditions than under better weather conditions. However, total delay under good weather conditions considerably outweighs the total delay experienced under poor weather conditions. The report also demonstrates a quantitative relationship between average delay and the demand/capacity ratio at the airport. This should prove to be especially useful in the investment analyses of airport improvements.
