The Next Generation Air Transportation System is a transformative change in the management and operation of how we fly. NextGen will enhance safety, reduces delays, save fuel and reduce aviation’s environmental impact. This comprehensive initiative, which is already providing benefits, integrates new and existing technologies, including satellite navigation and advanced digital communications. Airports and aircraft in the National Airspace System will be connected to NextGen’s advanced infrastructure and will continually share real-time information to provide a better travel experience.
