... 2 Although there are opportunities to increase runway efficiency, such as less separation, parallel approaches, and so on, the realizable benefits of such are not yet clear. For example, wake vortex separation requirements may limit separation reduction, and local community resistance to noise and night flights may limit the introduction of new approach routes or extended hours that would increase the capacity of existing runways.

... Technical Constraints The technical realities and constraints to which NextGen programs are subject run the gamut from the capabilities of legacy hardware to costs of certification to the challenges of large-scale system integration. The great majority of the tasks facing NextGen involve software and information and communications technology -- the systems architecture has implications for how software 3  The 2007 National Research Council report Human-System Integration in the System Development Process: A New Look (The National Academies Press, Washington, D.C.)

... Ensuring clear processes and plans for any changes to the operational infrastructure, such as the development of procedures and airspace that take full advantage of the new technical capabilities of NextGen, will be important. Given the humanintensive nature of operating the national airspace, there are also challenges related to design for organizations and to human-system integration, including robustness of the combined humanmachine interaction, along with human factors concerns with the implementation of new technical functions.
