KCOS Runway 17L/35R — City of Colorado Springs Municipal Airport

Name: KCOS Runway 17L/35R wind climatology 2005–2025
Creator: ATIS Alerts

13,500 × 150 ft concrete · true headings 180° / 000° · field elevation 6,187 ft

Runway 17L/35R at City of Colorado Springs Municipal Airport (KCOS) in Colorado Springs, CO is 13,500 ft long and 150 ft wide, concrete, with true headings 180° and 000°. The FAA record lists ILS/DME (CAT I) and MALSR approach lights on runway 17L. Over 2005–2025 the wind gave runway 17L the headwind 43% of the time and runway 35R 54.3%, with a crosswind above 15 kt in 2.3% of wind hours. KCOS has no digital ATIS, so the active runway is not known; the wind-favored end and the ATIS Alerts prediction are estimates.

Runway 17L/35R — current operational status

What the D-ATIS, the tower and current NOTAMs state now. The published FAA baseline (NASR) is a separate line in the overview below and does not reflect temporary closures.

STATUS UNKNOWN

No received NOTAM closes or restricts this runway, but the NOTAM stream has no complete initial load and the airport has no tower or D-ATIS feed. No current closure information.

Sources: Published FAA baseline (OurAirports/NASR record) · FAA NOTAMs. Runway NOTAMs stream live from the FAA NOTAM Management Service (SWIM); the official text is shown verbatim below the card. Always confirm with a current briefing.

NOTAMs for runway 17L/35R

Official text as issued; grouped for reading only. “Scheduled” means not yet in effect. NOTAMs are received live from the FAA NOTAM Management Service through SWIM and recorded since Sep 19, 2026; a NOTAM issued before that and not re-issued since may be missing. Get a full briefing before flight.

Current runway assignment is not available from D-ATIS at KCOS. The wind components below show which end the wind favors; the section after it is an ATIS Alerts prediction. Neither is an ATC assignment.

ATIS Alerts Predicted Runway is an estimate from the TAF wind forecast, runway geometry (most headwind, crosswind penalised, tailwind over 5 kt avoided, longest runway breaks ties), the current stated configuration and any stated closures. Each row lists its reasons; “no runway favored” is a genuine answer under variable or light wind, never replaced by a guess. It is not an ATC assignment and does not know about noise abatement or traffic flow unless the recorded history shows them. TAF issued 0520Z (11:20 PM MDT).

“Most wind-favored end” is meteorological analysis: the share of steady-wind hours (2005–2025) in which this end had the most headwind of every open runway end at KCOS. It does not mean ATC selected the runway that often (parallel ends with the same heading share the credit equally). Observed runway use, where available, is the configuration-history section above.

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; 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.
Flowis the compass direction of the stated arrival ends (eight sectors, named only when every arrival end points within 30° of the others and clear of a sector edge); a tower's own configuration name is used when it carries a direction word. Stored separately from the runway sets.
Equipment, LAHSO and frequencies come from the FAA NASR 28-day subscription (cycle 2026-10-01): approach lights, visual glide slope, edge / centerline / touchdown-zone lights, REIL, ILS components with FAA status, RVR, markings, LAHSO hold-short points and available landing distances, and facility frequencies with their published sectorization. Outage annotations are readings of the NOTAM or D-ATIS text shown beside them. Blank FAA fields read “Not available”.
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), excludes stated closures, and — once a wind sector has 24 h of recorded use — adjusts confidence by what the facility did under similar wind; every row lists its reasons. It does not model noise abatement or flow programs beyond what the record shows.
History thresholds: usage shares need 12 / 48 / 168 recorded hours for the 24-hour / 7-day / 30-day windows; a wind sector needs 24 h and 5 days; time-of-day needs 7 days and 20 h per daypart; flow shares need 48 h. Below a bar the module says so instead of showing a percentage.
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.
PIREPs: official reports from aviationweather.gov are attached only when the text names this runway and the report is tied to KCOS by identifier or by position within 15 NM. 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 1 min ago; usage rollups every 3 h; climatology through 2025-12-31.

⚠️ ATIS Alerts provides informational runway analysis based on available weather, the tower's TFDM configuration and NOTAMs received through FAA SWIM, D-ATIS text, FAA data and historical observations. Active runways shown here are what the tower or its D-ATIS stated and may lag or be misread; NOTAM coverage is not complete; predicted runways are an ATIS Alerts estimate, not an ATC assignment; equipment states are readings of the official text shown with them.
