Definition
An FAA database that stores official information about the facilities, equipment, and services that make up the National Airspace System, including navigation aids, communication equipment, radar sites, and air traffic control facilities. It serves as the authoritative record used by FAA staff to track facility status, capabilities, and configuration across the country.
Plain English
A central FAA system that keeps track of every piece of equipment and facility used to run U.S. airspace — things like navigation beacons, radio sites, radar, and control towers — so the FAA always knows what exists, where it is, and whether it is working.
Context Anchor
A pilot may see NFIS in FAA acronym lists, facility references, or background material related to NOTAMs and FAA data systems.
Why Pilots Care
Pilots don't query NFIS, but the accuracy of the navigation aids, frequencies, and facility information shown on charts and in NOTAMs depends on what's recorded in it. When a VOR goes out of service or a new facility comes online, NFIS is part of how that change gets tracked and pushed to the products pilots use.
Intuition Check
NFIS is not a cockpit display, radio service, or weather product. It is an FAA information system used behind the scenes to manage facility data.
Example Sentence 1
When the technicians decommissioned the old VOR, the change was recorded in NFIS so the updated status would flow through to charts and NOTAMs.
Example Sentence 2
Dispatch used the NFIS to confirm the status of nearby facilities during route planning.
