Analysis of Environmental Impact of Eliminating Arrival Hold Short Operations for Runway Crossings at Dallas/Ft. Worth Airport

This paper analyzes the environmental impact of eliminating arrival aircraft stops at active runway crossings. As the air traffic demand increases, innovative operating procedures to either reduce or maintain environmental impact will be required. To improve surface operation efficiency, as well as potentially reduce environmental harm, eliminating arrival aircraft stops at active runway crossings is being explored. This paper describes an analysis of active runway crossing operations for arrival aircraft, as well as a comparison of the fuel and emissions environmental impact of maintaining current active runway crossing operations versus eliminating aircraft hold short operations at active runway crossings. Three previously developed software tools were used in the data analysis. The results indicate a decrease in both emissions exposure levels and fuel consumption prior to a runway crossing on the order of 30 % with the implementation of the operating procedure that eliminates hold short operations and allows continual taxi for runway crossings.
