Airspace Flows & Delays gives pilots and flight operations teams a fast view of public aviation data: FAA airport delays and closures, ground stops, METAR and TAF weather, aviation weather hazards, NOAA radar, FAA ATCSCC traffic management plans, and FAA airport documents including airport diagrams, procedures, and Chart Supplement pages. Use watchlists and local alerts to monitor important airports, open FAA plates and diagrams, check traffic-management impacts, and brief changing airport conditions quickly. Airspace Flows & Delays uses public FAA, NOAA, National Weather Service, and AviationWeather.gov sources. It is an advisory situational-awareness tool and is not a replacement for official flight planning, air traffic control instructions, dispatch release, certified EFB products, or regulatory compliance.
