KORD Runway 09C/27C — Chicago O'Hare International Airport
11,245 × 200 ft concrete · true headings 090° / 270° · field elevation 680 ft
Runway 09C/27C at Chicago O'Hare International Airport (KORD) in Chicago, IL is 11,245 ft long and 200 ft wide, concrete, with true headings 090° and 270°. Over 2005–2025 the wind gave runway 09C the headwind 36.6% of the time and runway 27C 57.7%, with a crosswind above 15 kt in 3.1% of wind hours. KORD publishes a digital ATIS, so this page shows the runway the tower is actually using right now and builds a record of how often each end is assigned.

ATIS Alerts Predicted Runway is an estimate from the TAF wind forecast and runway geometry (most headwind, crosswind penalised, tailwind over 5 kt avoided, longest runway breaks ties). It is not an ATC assignment and does not know about noise abatement, traffic flow or construction unless the D-ATIS states them. TAF issued 2320Z (6:20 PM CDT).

Runway 09C/27C numbers are magnetic; the stored geometry and every wind calculation on this page are TRUE north, so they never need a variation correction. Magnetic variation here is about 4.0°W (World Magnetic Model). Displaced thresholds, declared distances (TORA/TODA/ASDA/LDA), approach lighting, PAPI/VASI, ILS equipment and traffic-pattern direction are FAA NASR fields not yet loaded — they are omitted rather than guessed.
Recorded runway use at KORD — last 30 days
How often the tower's TFDM configuration listed each end for arrivals and departures (the tower's own statement, via FAA SWIM).
Over the last 30 days ATIS Alerts captured 205 hours of stated runway configuration at KORD (8.5 days, 1 configuration change). Shares are the fraction of those hours in which the tower's TFDM system listed each end.

Runway 09C/27C closure history
Runway NOTAM history begins when the NOTAM feed goes live (next phase).
D-ATIS broadcasts recorded since Sep 10, 2026 declared runway 09C closed on 0 days and runway 27C closed on 0 days in the last 30 days. Scheduled and unscheduled closure NOTAMs, with start and end times and the official text, will appear here once ATIS Alerts records runway NOTAMs; there is no retrievable archive, so history accrues from that date forward.

Methodology and sources
Short version below; the full write-up is at Runway Intelligence methodology, and every launched airport is listed on the Runway Intelligence hub.
- Active runwayscome first from the tower's TFDM (Terminal Flight Data Manager) airport configuration, received as structured data through the FAA SWIM Cloud Distribution Service at towers that have it (KORD does); otherwise from the airport's D-ATIS text (community relay of the FAA broadcast) with an open, tested parser, and the broadcast text is always shown. Every change is recorded, so “recorded use” is what the facility stated, never an inference. ATIS Alerts is not an FAA product and this is not FAA data; SWIM content is for non-operational use.
- Wind components use the current METAR (aviationweather.gov) against TRUE runway headings from the OurAirports/FAA runway record.
- Runway visual range, tower demand and traffic-management restrictions come from FAA SWIM: STDDS Airport Data (RVR and light settings, about 130 airports) and TFDM (15-minute runway demand, APREQ/MIT restrictions). Each block is stamped with its own time; none of it is an FAA product or a clearance.
- Predicted runway scores each open end from the TAF wind (headwind, crosswind penalty, tailwind avoidance, longest-runway tie-break); confidence falls with forecast distance, gusts and TAF age. It does not model noise abatement or flow programs.
- Climatology: Iowa Environmental Mesonet ASOS archive, one observation per hour, 45° wind sectors, percentiles via t-digest; runway geometry is today's record applied to all years. Methodology v1.
- Approaches: FAA d-TPP metafile, current charting cycle; plates link to aeronav.faa.gov. No minimums are reproduced.
- Data freshness: METAR and D-ATIS refresh every minute on this page; the D-ATIS recorder ran 2 min ago; the tower TFDM feed last delivered 1 min ago; climatology through 2025-12-31.
