Abstract
The Next Generation Air Transportation System (NextGen) represents the transformation of the National Airspace System (NAS) using 21 century technologies to ensure future safety, capacity and environmental needs are met. NextGen will be realized through investments in research and development, technologies, operational changes, and the coordinated efforts of private industry and federal NextGen Partner Agencies. The National Aeronautics & Space Administration (NASA) Aeronautics Research Mission Directorate’s (ARMD) Strategic Architecture and Analysis (SAA) office uses NAS-wide modeling and simulations to evaluate these alternatives and estimate the corresponding stakeholder benefits under future scenarios that consider different objectives and operating environments. The analysis contained in this paper, which was started in FY2012, expands upon prior SAA work supporting the Joint Planning & Development Office (JPDO) Interagency Portfolio & Systems Analysis portfolio assessments to include a far-term, full vision of NextGen in 2040 as well as the incorporation of unmanned aircraft systems (UAS). This paper describes the formulation and evaluation of the NextGen alternatives in 2025 and 2040, methods for evaluating their performance and provides an initial set of results.
