When first conceived by the Federal Aviation Administration (FAA) in 2004, NextGen was primarily aimed at replacing a badly outdated clearance-based operational control system with a trajectory-based system, utilizing satellite-fed global positioning data to greatly improve aircraft positioning and situational awareness.
Over time, NextGen has evolved to become a comprehensive overhaul of every aspect of our national airspace system (NAS). Major new technologies and capabilities are being introduced to completely change how data is collected and shared between air traffic control and aircraft in the air and on the ground. This huge undertaking will result in greater safety, efficiency and cost savings, while reducing environmental impacts and spinning off a host of other benefits that are not yet fully visualized.
NextGen is well underway. Installation of hardware and software began in the 2000s and is now largely complete, despite a prolonged work shutdown during the COVID-19 pandemic. With this foundational phase completed, it is now moving into an operational phase of full integration and implementation of all major planned systems — a phase that is expected to be complete this decade.
Initial operational rollout is underway within the nation’s busiest airspace corridor in the Northeast, including the major airports of Boston, New York, Philadelphia and Washington. Subsequent rollouts are planned for the Denver-to-Northwest and Mid-Atlantic-to-Southeast corridors.
