KLTS Runway 18L/36R — Altus Air Force Base

9,001 × 150 ft asphalt · true headings 180° / 360° · field elevation 1,382 ft

Runway 18L/36R at Altus Air Force Base (KLTS) in Altus, OK is 9,001 ft long and 150 ft wide, asphalt, with true headings 180° and 360°. The FAA record lists Localizer with glideslope (CAT I) and SALSF approach lights on runway 18L. Over 2006–2025 the wind gave runway 18L the headwind 58.2% of the time and runway 36R 39.2%, with a crosswind above 15 kt in 1.3% of wind hours. KLTS has no digital ATIS, so the active runway is not known; the wind-favored end and the ATIS Alerts prediction are estimates.

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 0100Z (8:00 PM CDT).

Runway 18L/36R 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, 5.0°E (2015), 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.

“Most wind-favored end” is meteorological analysis: the share of steady-wind hours (2006–2025) in which this end had the most headwind of every open runway end at KLTS. 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.

⚠️ 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.
