"The NextGen Implementation Plan provides an overview of the FAA's [Federal Aviation Administration] ongoing transition to the Next Generation Air Transportation System. The Plan lays out the agency's vision for transforming the way things work in our nation's skies and at our nation's airports by the end of the mid-term. The Plan further provides a status report on the NextGen deployments, capabilities and benefits we have already introduced into the National Airspace System (NAS), as well as the goals we have set and commitments we have made in support of our mid-term vision. Additionally, the Plan addresses the harmonization work we are doing with the global aviation community to ensure aircraft operating globally receive the operational benefits in various international air traffic environments. The primary goals of NextGen are to enhance the safety and reliability of air transportation, to improve efficiency in the NAS and to reduce aviation's impact on our environment."
