| 摘要： | This report summarizes the results of an initial study to estimate the yearly delay reduction provided by the initial operational capability (IOC) Integrated Terminal Weather System (ITWS) at Hartsfield-Jackson Atlanta International Airport (ATL). Specific objectives of this initial study were to: analyze convective weather operations at ATL to determine major causes of convective weather delay and how those might be modeled quantitatively; provide estimates of the ATL ITWS delay reduction based on the 'Decision/Modeling' method using questionnaires and interviews with Atlanta Terminal Radar Approach Control (TRACON) and Air Route Traffic Control Center (ARTCC) operational ITWS users; assess the 'reasonableness' of the model-based delay reduction estimates by comparing those savings with estimates of the actual weather-related arrival delays at ATL. In addition, the reasonableness of model-based delay reduction estimates was assessed by determining the average delay savings per ATL flight during times when adverse convective weather is within the coverage of the ATL ITWS; conduct an exploratory study confirming the ATL ITWS delay savings by comparing Aviation System Performance Metrics (ASPM) database delays pre-and post-ITWS at ATL; assess the accuracy of the 'downstream' delay model employed in this study by analyzing ASPM data from a major US airline; and make recommendations for follow-on studies of the ITWS delay reduction at Atlanta and other IOC ITWS facilities. All of these objectives were achieved. |
