KSMF Runway 17L/35R — Sacramento International Airport

8,605 × 150 ft concrete · true headings 181° / 001° · field elevation 27 ft

Runway 17L/35R at Sacramento International Airport (KSMF) in Sacramento, CA is 8,605 ft long and 150 ft wide, concrete, with true headings 181° and 001°. 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 68.2% of the time and runway 35R 31.8%, with a crosswind above 15 kt in 0.2% of wind hours. KSMF publishes its tower configuration on FAA SWIM, so this page shows the runway the tower is actually using right now, today's configuration changes, and a growing record of how often each end is assigned.

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.

NO CLOSURE REPORTED
  • The tower's TFDM closure record lists no closure for this runway and the current D-ATIS names no closure, restriction or outage for it. No received NOTAM closes or restricts this runway, but the NOTAM stream has no complete initial load yet — verify NOTAMs before flight.

Sources: Published FAA baseline (OurAirports/NASR record) · FAA NOTAMs · Tower TFDM configuration (FAA SWIM) · D-ATIS · Tower TFDM 0758Z (12:58 AM PDT) · D-ATIS 0753Z (12:53 AM PDT).

Today's runway configuration at KSMF

Meaningful configuration changes recorded from the tower's TFDM feed — the facility's own statements, not estimates.

Oct 29, 2026 (airport-local day): 0 configuration changes since local midnight, from the tower's TFDM configuration ATIS Alerts recorded. A change is a different arrival or departure set; a new ATIS letter with the same runways is folded into the row it belongs to. The history section below counts the same way over rolling windows.

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; recorded tower use since Oct 16, 2026 (302 h) is an input wherever a wind sector has 24 h on record. 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 (10:20 PM PDT).

Counts the tower's surface system expects per runway over the next two hours — the tower's plan, not an ATIS Alerts estimate and not an ATC assignment. A runway with zero expected demand is not in the plan for that period. During a runway change the plan can lag the configuration above for a few minutes (flights already assigned to the old runways stay counted there until reassigned).

Runway 17L/35R numbers are magnetic; the stored geometry and every wind calculation on this page are TRUE north, so they never need a variation correction. Magnetic headings use the FAA's published variation for this airport, 13.0°E (2020), the same value printed on the FAA airport diagram. Surface condition, treatment, weight bearing, thresholds and traffic pattern are from the FAA NASR record (cycle 2026-10-01); lighting, ILS and LAHSO are in their own sections above. Declared distances are not shown in this phase.

Bars: share of each local hour in which an end of this runway was named for arrivals. Patterns are described, not explained.

Observed runway usage — 302 hours of tower TFDM runway configuration history collected · 2 distinct configurations observed · through Oct 29, 2026. Shares are the fraction of recorded hours in which the tower's TFDM configuration listed each end. Wind sectors use the wind reported when each configuration began. Nothing here is inferred from wind; the wind-favored analysis for KSMF is a separate module. 90-day, 12-month and seasonal views appear once the record is long enough.

“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 KSMF. 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 (KSMF 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.
  • 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 KSMF 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 3 min ago; the tower TFDM feed last delivered 5 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. Not an FAA product. Not for operational use. Always verify with official FAA-approved preflight weather sources before flight.
