![]() ![]() As already stated, the navigation system will be changed from ground-based communication to satellite-based navigation. However, this architecture is fragmented and many issues are raised: an airplane’s path through its route is not optimized, and the path may change its direction from one zone to another, the destination airport’s capacity is limited by the current regulations of minimum aircraft separation distance due to navigation limitations, the real-time weather information is not integrated into the system, and communications are mainly voice-based, etc. Each aircraft goes through different layers and possibly various zones of this architecture as it takes off from an airport until its lands at another airport (Donohue and Zellweger 2001). National Air Space (NAS) system using a five-layer architecture architecture. The Air Traffic Organization (ATO) is responsible for ensuring aircraft navigation in the U.S. Nineteen major airlines, with more than a billion dollars in annual total revenue, along with other 57 national and regional airlines, transport 793 million passengers and realize 53 billion revenue ton-miles. ATN serves both military and commercial aircraft with its 19,782 airports, including 547 are commercial airports. ![]() ATN it was seen as necessary to view it through a lens of evolutionary adaptation rather than rigid systems design. Therefore, in order to understand changes in the U.S. In systems technical constraints and social and behavioral complexity are of essential essence”. ATN is a “large-scale in which humans and technical constituents are interacting, adapting, learning, and coevolving. ATN) enterprise.Ī sociotechnical system sociotechnical system like the U.S. This project is unique to the FAA because of its large scale, the huge number of stakeholder(s) stakeholder(s) involved, the properties of the system of interest system of interest, and the revolutionary changes required in the U.S. air transportation infrastructure infrastructure from a fragmented ground-based navigation system to a net-centric satellite-based navigation system. federal organizations to transform the U.S. NextGen is an unprecedented effort by multiple U.S. This case study presents the systems engineering systems engineering and enterprise systems engineering (ese) enterprise systems engineering (ese) efforts in the Next Generation (NextGen) Air Transportation Systems by the Federal Aviation Administration (FAA 2008). ![]()
