Every page on AirportIQ HQ is generated from an offline build pass against the following public data sources. The build turns those files into static pages, so no live API call sits between you and a page load.
Airport master record
The primary source for every airport entry is the OurAirports public CSV (fetched 2026-09-17), which aggregates the FAA's NASR (National Airspace System Resource) Airport Master Record / Form 5010 dataset together with ICAO identifiers for international cross-reference. The CSV is published as a community service and is the de-facto canonical form of the FAA's data outside the agency's own download portal at adip.faa.gov. The FAA also publishes its Airport Data & Contact Information (Form 5010) directly, which is the underlying source for OurAirports' US records.
Cross-reference for global codes
For global airport-code cross-checks we use the OpenFlights airports.dat dataset published in the jpatokal/openflights repository on GitHub. This is a long-running community dataset of roughly 7,000 airports worldwide, maintained as an open file and licensed for free use.
FAA region map
The nine FAA regions and their state assignments come from the FAA's official "Regional Offices" page. The FAA-region and time-zone labels previously shown on airport pages were removed on 2026-09-23 because no data file in this project records them.
Airline directory
The airline directory presents each carrier's name and its IATA and ICAO codes, matched by code against the OpenFlights airlines.dat file. Where that file carries a radio callsign or a country for the matched row, they are shown; nothing else about a carrier is published here.
Traffic, parking, and TSA estimates
These sections were removed from every airport page on 2026-09-23. No file in this project records per-airport traffic, runway, parking, TSA or airline facts with a named source, so no such figures are published here.
What AirportIQ HQ does not do
We do not call live flight-status APIs, weather services, or carrier reservation systems. The site is a static reference directory generated from periodic snapshots, not a real-time information service.
