NextGen

NextGen is a comprehensive overhaul of the United States' National Airspace System (NAS), led by the Federal Aviation Administration (FAA) in collaboration with NASA, MITRE Corporation, and other stakeholders, including Boeing, Lockheed Martin, and Northrop Grumman. The program aims to increase the efficiency, safety, and capacity of the NAS, while reducing costs and environmental impact, as outlined in the Vision 100-Century of Aviation Reauthorization Act signed by President George W. Bush. NextGen will leverage advancements in aviation technology, such as Automatic Dependent Surveillance-Broadcast (ADS-B) and Performance-Based Navigation (PBN), developed by organizations like Honeywell International and Rockwell Collins. The program's success will depend on the cooperation of various entities, including Air Line Pilots Association, Airlines for America, and the National Transportation Safety Board.

Introduction

NextGen is a critical component of the FAA's efforts to modernize the NAS, which will enable the safe and efficient management of increasing air traffic demand, as forecasted by the International Air Transport Association (IATA) and the Air Transport Association of America (ATA). The program builds upon previous initiatives, such as the FAA's Free Flight Phase 1 and National Airspace System Architecture, developed in conjunction with IBM, Cisco Systems, and Microsoft. NextGen will integrate various technologies and systems, including those developed by General Electric, United Technologies, and BAE Systems, to provide a more efficient and adaptable air traffic management system. The program's introduction is supported by key stakeholders, including Delta Air Lines, American Airlines, and the National Business Aviation Association.

History

The concept of NextGen was first introduced in the early 2000s, as the FAA began to explore ways to address the growing demands on the NAS, with input from experts at Stanford University, Massachusetts Institute of Technology (MIT), and the University of California, Berkeley. In 2003, the FAA published the Operational Evolution Plan (OEP), which outlined the agency's vision for the future of the NAS, in collaboration with The Boeing Company and Lockheed Martin Aeronautics. The OEP identified key areas for improvement, including the use of ADS-B and PBN, developed with the support of NASA's Aeronautics Research Mission Directorate and the European Organisation for the Safety of Air Navigation (EUROCONTROL). The FAA then established the Joint Planning and Development Office (JPDO) to oversee the development of NextGen, with participation from United States Department of Defense (DoD), National Oceanic and Atmospheric Administration (NOAA), and the National Institute of Standards and Technology (NIST).

Architecture

The NextGen architecture is designed to be modular and flexible, allowing for the integration of new technologies and systems as they become available, such as those developed by Google, Amazon Web Services, and Microsoft Azure. The architecture is based on a Service-Oriented Architecture (SOA) approach, which enables the sharing of data and services across different systems and stakeholders, including Eurocontrol, International Civil Aviation Organization (ICAO), and the Federal Communications Commission (FCC). The NextGen architecture includes several key components, such as the System Wide Information Management (SWIM) system, developed in partnership with IBM, Oracle Corporation, and SAP SE. SWIM will provide a common platform for sharing data and information across the NAS, with support from The Weather Channel and National Weather Service.

Components

NextGen consists of several key components, including ADS-B, PBN, and SWIM, developed with the participation of Honeywell Aerospace, Rockwell Collins, and Garmin International. ADS-B is a surveillance system that uses GPS and other technologies to provide precise location and velocity information for aircraft, as demonstrated by NASA's ADS-B Technology project. PBN is a navigation system that enables aircraft to fly more precise and efficient routes, using data from FAA's Wide Area Augmentation System (WAAS) and European Geostationary Navigation Overlay System (EGNOS). SWIM is a data sharing platform that enables the exchange of information across different systems and stakeholders, with support from MITRE Corporation and Stanford Research Institute (SRI).

Implementation

The implementation of NextGen is a complex and ongoing process, involving the coordination of multiple stakeholders and the integration of new technologies and systems, such as those developed by Cisco Systems, Juniper Networks, and VMware. The FAA has established a phased approach to implementation, with key milestones and deadlines, as outlined in the FAA's NextGen Implementation Plan. The plan includes the deployment of ADS-B and PBN capabilities, as well as the development of new procedures and training programs for air traffic controllers and pilots, in collaboration with Air Line Pilots Association and Aircraft Owners and Pilots Association (AOPA). The implementation of NextGen is supported by key stakeholders, including Delta Air Lines, American Airlines, and the National Business Aviation Association.

Benefits_and_Challenges

The benefits of NextGen include increased efficiency, safety, and capacity, as well as reduced costs and environmental impact, as reported by the National Academy of Sciences and the Government Accountability Office (GAO). NextGen is expected to enable the NAS to accommodate growing demand for air travel, while reducing delays and cancellations, as forecasted by the International Air Transport Association (IATA) and the Air Transport Association of America (ATA). However, the implementation of NextGen also poses significant challenges, including the need for significant investment in new technologies and infrastructure, as well as the coordination of multiple stakeholders and systems, with support from The Boeing Company, Lockheed Martin, and Northrop Grumman. The FAA and other stakeholders must also address concerns related to cybersecurity and privacy, as highlighted by the National Institute of Standards and Technology (NIST) and the Federal Bureau of Investigation (FBI).
