Methods for estimating constant and variable sector capacity based on an airspace complexity metric, simplified dynamic density, are proposed. Simplified dynamic density is a weighted sum of seven traffic components that contribute to airspace complexity. Constant and variable estimates of maximum sector capacity, based on projected flight tracks, are used(More)
This paper compares airspace design solutions for dynamically reconfiguring airspace in response to nominal daily traffic volume fluctuation. Airspace designs from seven algorithmic methods and a representation of current day operations in Kansas City Center were simulated with two times today's demand traffic. A three-configuration scenario was used to(More)
Seventy-eight air traffic sector configurations, recorded in operational data for Kansas City Air Route Traffic Control Center on February 8, 2007, were analyzed. A method is used to select a sequence of configurations and trigger times from the operational sector combination data. The selection process considers two key characteristics of sector combining(More)
Flexible Airspace Management (FAM) concept offers to dynamically modify the center/sector boundaries in such way that the airspace structure is reconfigured to better distribute unbalanced traffic demands across sectors. A set of airspace design algorithms were used in the human-in-the-loop simulation to assess possible benefits of the FAM concept. In the(More)
