This thesis examines the potential capacity and delay benefits that would result if a "fanway" configuration of runways were utilized for arrival aircraft operations at a major airport. The Federal Aviation Administration's Delay Simulation Model was employed to determine capacity and delay values so that a conventional runway configuration could be compared with the fanway approach. Various aircraft demand schedules were then applied to the configurations for both present and future airport scenarios at Denver's Stapleton International Airport. In addition to the capacity and delay comparisons that were contained in this thesis, the thesis also included a brief summary of the available air traffic control models in. general and a detailed description of the Delay Simulation Model in specific. Furthermore, the thesis also contains a brief description of past, present, and future trends of U. S. aviation and air traffic control systems. / M.S.
