The Next Generation Air Transportation System's (NextGen) goal is the transformation of the U.S. national airspace system through programs and initiatives that could make it possible to shorten routes, navigate better around weather, save time and fuel, reduce delays, and improve capabilities for monitoring and managing of aircraft. A Review of the Next Generation Air Transportation provides an overview of NextGen and examines the technical activities, including human-system design and testing, organizational design, and other safety and human factor aspects of the system, that will be necessary to successfully transition current and planned modernization programs to the future system. This report assesses technical, cost, and schedule risk for the software development that will be necessary to achieve the expected benefits from a highly automated air traffic management system and the implications for ongoing modernization projects. The recommendations of this report will help the Federal Aviation Administration anticipate and respond to the challenges of implementing NextGen.

The FAA is planning and coordinating R&D for the next generation air transportation system (NextGen). Transitioning to the NextGen will require FAA to continue to acquire new air traffic control (ATC) systems on schedule and on budget. NextGen includes system acquisitions but is a significantly larger initiative involving multiple federal agencies, such as NASA, which conducted aeronautics R&D for NextGen, and non-federal aviation stakeholders, such as aviation equipment manufacturers, airports, and aircraft operators. This report addressed: (1) FAA¿s ATC systems acquisition activities; (2) key NextGen planning and transition issues; and (3) key challenges that FAA faces in implementing NextGen. Illustrations.

To prepare for forecasted air traffic growth, the Federal Aviation Administration (FAA), in partnership with other federal agencies and the aviation industry, is planning and implementing the Next Generation Air Transportation System (NextGen), a new satellite-based air traffic management system that will replace the current radar-based system and is expected to enhance the safety and capacity of the air transport system. This report reviewed FAA's metrics for: (1) tracking the status of NextGen programs and the implementation of NextGen capabilities, the reliability of those metrics, and any limitations or gaps; and (2) measuring the performance and outcomes of NextGen capabilities that are implemented and any limitations.

The Next Generation Air Transportation System (NextGen) is an effort begun in 2003 whose goals include improving the capacity, efficiency, and safety of the U.S. air transportation system and also enabling reduction in noise, pollution, and energy use. The Federal Aviation Administration and various stakeholders, including equipment providers, airlines, and contractors, are currently implementing both near-term and midterm capabilities of this effort. Interim Report of a Review of the Next Generation Air Transportation System Enterprise Architecture, Software, Safety, and Human Factors is part of a larger project to examine NextGen's enterprise architecture and related issues. This interim report provides an initial assessment focusing on challenges of system architecture for software-intensive systems.

"The Federal Aviation Administration(FAA) is developing andimplementing a broad transformationof the national airspace systemknown as the Next Generation AirTransportation System (NextGen).NextGen is a complex undertakingthat requires new technologies andsupporting infrastructure andinvolves the activities of severalagencies as well as private industry.This report provides information onthe effectiveness of (1) FAA's and thefederal partner agencies' mechanismsfor collaborating and leveragingresources to develop and implementNextGen, and (2) FAA's mechanismsfor working with and transferringtechnology to or from privateindustry. To do this, we assessed FAAand partner agency mechanismsagainst applicable agreements, theagencies' own guidance for theseactivities, as well as applicable keypractices that GAO has reported canenhance federal collaborative efforts. GAO recommends that FAA and theDepartments of Defense (DOD) andHomeland Security (DHS) worktogether to develop mechanisms thatwill enhance collaboration andtechnology transfer between theagencies. GAO and others haveoutstanding recommendationsrelated to interaction with industrythat FAA has begun to address..."
