Definition
A long-term FAA-led modernization program that transforms the United States National Airspace System from ground-based radar surveillance and voice communication to satellite-based navigation, surveillance, and digital data communication. NextGen integrates technologies such as Automatic Dependent Surveillance-Broadcast (ADS-B), Performance-Based Navigation (PBN), System Wide Information Management (SWIM), and Data Comm to increase airspace capacity, improve safety, reduce delays, and lower fuel burn and emissions.
Plain English
An ongoing upgrade of how aircraft are tracked, navigated, and talked to in U.S. airspace, moving from older radar and radio methods to newer satellite and digital ones.
Context Anchor
You may see this term in discussions of modern air traffic control, updated cockpit equipment, new procedures, and changes to how aircraft are routed through U.S. airspace.
Derivation
“Next generation” means the next major stage of development. In this term, it points to a planned move from older air traffic methods toward a newer, more connected national system.
Why Pilots Care
It drives requirements for new navigation equipment and changes how flights are routed and managed.
Grounding Statement
A pilot may experience this as more precise routing, better traffic information, and clearer flow through busy airspace.
Intuition Check
Do not read “Next Generation” as a new type of airplane or a single piece of equipment. Here it means a broad FAA modernization program for the whole air transportation system.
Example Sentence 1
The ADS-B Out requirement in most controlled airspace is one of the most visible results of NextGen for general aviation pilots.
Example Sentence 2
Training materials now include information about the Next Generation Air Transportation System and its effect on daily operations.
