    Why it is in this group

    • The name "faa_delays_get_advisory" says "get": a word for reading.
    Description, as the server wrote it
    Get the full text of one ATCSCC advisory by its number and UTC date. faa_delays_list_advisories lists the advisories issued on a date with their numbers, and the advisory reference that faa_delays_list_active_events and faa_delays_get_airport_status return on program rows and faa_delays_get_operations_plan returns for the plan names one directly. Advisory text carries what the status feed omits: program rate by hour, delay assignment mode, scope, comments, and the operations plan's active constraints and runway closures. Advisory numbers restart at 1 each UTC day, and older advisories remain available.

    Why it is in this group

    • The name "faa_delays_get_airport_status" says "get": a word for reading.
    Description, as the server wrote it
    Get the current FAA traffic management status for one or more US airports: a headline status, every active event (ground stop, Ground Delay Program with its delay profile, arrival or departure delay, closure, deicing) with reason and times, and the runway configuration and airport arrival rate. Every row carries the airport's ARTCC, and its coordinates come from the feed when the airport is listed (absent when the feed omits them) and from the NASR directory otherwise; both place a departure airport against a program's includedFacilities and departureScopeNm. Airports are FAA 3-character identifiers (SEA, ORD, JFK) or their ICAO codes (KSEA, PHNL); a code that names no US airport is rejected. The FAA feed lists only airports with an active event, so a known airport absent from it returns status no_active_events, and runway configuration is available only for listed airports.

    • The name "faa_delays_get_operations_plan" says "get": a word for reading.
    Description, as the server wrote it
    Get the FAA Command Center's current operations plan: terminal programs (possible ground stops and delay programs by airport) and en-route initiatives (route closures, severe-weather avoidance plans) expected later in the day, each with its planned UTC time and stated likelihood, plus current ATCSCC announcements. The advisory reference opens the full plan text with faa_delays_get_advisory, including active constraints and runway closures this summary omits.

    Why it is in this group

    • The name "faa_delays_list_active_events" says "list": a word for reading.
    Description, as the server wrote it
    List every active FAA traffic management event across the National Airspace System in one call: ground stops, Ground Delay Programs, Airspace Flow Programs, arrival and departure delays, airport closures, closure NOTAMs, and deicing. Rows are sorted by severity (closures, ground stops, then GDPs and then AFPs each by average delay, arrival/departure delays by band maximum, closure NOTAMs, deicing) and carry the reason, delay figures, times, and an advisory reference for faa_delays_get_advisory. Use faa_delays_get_airport_status for the full detail of one airport, including its GDP delay profile and runway configuration.

    Why it is in this group

    • The name "faa_delays_list_advisories" says "list": a word for reading.
    Description, as the server wrote it
    List the ATCSCC advisories issued on one UTC date, newest first, from the FAA advisories database's per-date index: ground stops and delay programs as issued, proposed, revised, and canceled, required reroutes, flow constrained areas, operations plans, and CDM compression advisories, including those no longer active and those on past dates, which the NAS Status feed does not carry. Each row gives the advisory number, control element, subject, any further title lines (a reroute's name, constrained area, and valid period), and send time; its number and date open the full text with faa_delays_get_advisory. Narrow by categories, control_element (an airport, its ICAO code, an ARTCC, or DCC for national advisories), or query (literal case-insensitive subject/details text, such as an FCA name); filters combine before limit and offset paging.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
