"instructions": "Real-time FAA National Airspace System status from the Command Center's NAS Status feed, public domain and informational only, not for flight operations. Start with faa_delays_list_active_events for everything active nationwide (ground stops, ground delay programs, airspace flow programs, arrival/departure delays, closures, deicing), or faa_delays_get_airport_status for specific US airports by FAA 3-character code (SEA, ORD) or ICAO code (KSEA, PHNL); faa_delays_get_operations_plan lists what the FAA expects later today. Program rows and the plan carry an advisory reference; its number and UTC date are the advisory_number and date of faa_delays_get_advisory, which returns the full advisory text: program rate, scope, comments, and the plan's active constraints. faa_delays_list_advisories lists the advisories issued on a UTC date, numbers included, newest first, and so reaches what the feed does not carry: programs already canceled, proposed programs, reroutes, and past dates. faa_delays_list_reference decodes event types, terms (AAR, EDCT, FCA), ARTCC codes, and the FAA pacing airports. The feed lists only airports with an active event: a known airport absent from it has no active FAA program, which does not guarantee on-time flights, and per-flight EDCTs are not in this feed. All times are UTC; the FAA updates the feed about once a minute and this server caches it for 60 seconds.
