KHPN Runway 11/29 — Westchester County Airport

Name: KHPN Runway 11/29 wind climatology 2005–2025
Creator: ATIS Alerts

4,451 × 150 ft asphalt · true headings 102° / 282° · field elevation 439 ft

Runway 11/29 at Westchester County Airport (KHPN) in White Plains, NY is 4,451 ft long and 150 ft wide, asphalt, with true headings 102° and 282°. Over 2005–2025 the wind gave runway 11 the headwind 37.1% of the time and runway 29 62.9%, with a crosswind above 15 kt in 0.8% of wind hours. KHPN 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.

Runway 11/29 — current status

NO CLOSURE REPORTED

The current D-ATIS names no closure, restriction or outage for this runway. Runway NOTAMs are not monitored yet — verify before flight.

Sources: FAA runway record (OurAirports) · D-ATIS · D-ATIS 1756Z (1:56 PM EDT). Runway NOTAM monitoring (closures, lighting, navaid outages) is scheduled for the next phase; until then this card reflects only the FAA runway record and the airport's own D-ATIS.

Wind-favored runway at KHPN right now: 34 (12 kt headwind) — a different runway than this one.

Components use TRUE runway headings and TRUE METAR wind. “Favored by wind” is arithmetic, not an ATC assignment.

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 1730Z (1:30 PM EDT).

Runway 11/29 overview

Physical characteristics from the FAA-derived runway record.

Length: 4,451 ft
Width: 150 ft
Surface: Asphalt
Runway lights: Lighted
Airport elevation: 439 ft
FAA record status: Open

Runway 11

True heading: 102°
Magnetic (approx.): ≈ 115°
FAA record: Open

Runway 29

True heading: 282°
Magnetic (approx.): ≈ 295°
FAA record: Open

Runway 11/29 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 12.7°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 KHPN — last 30 days

How often the D-ATIS named each end for arrivals and departures (the facility's own statement).

ATIS Alerts records every change of KHPN's D-ATIS and turns it into a log of which runways the facility named for arrivals and departures. Recording started Sep 18, 2026 — 2 hours captured so far. Usage statistics appear once 24 hours are on record, and become meaningful after a few weeks.

Historical wind and crosswind on runway 11/29

20-year hourly climatology from the ASOS archive, computed per runway end.

From 175,203 hourly observations at KHPN (2005–2025), 140,519 with a steady wind direction (19.8% calm, variable or direction-less). One observation per clock hour; TRUE headings against TRUE wind.

“Wind-favored” counts the hours this end had the most headwind of every open runway at KHPN — wind arithmetic, not an ATC assignment (parallel runways with the same heading share the credit equally). Recorded D-ATIS use, where available, is the section above.

IFR, thunderstorm (TS) and fog columns are airport-wide shares of hours; the crosswind and tailwind columns are specific to this runway. Prevailing = most common 45° wind sector among wind hours.

Runway 11/29 closure history

Runway NOTAM history begins when the NOTAM feed goes live (next phase).

D-ATIS broadcasts recorded since Sep 18, 2026 declared runway 11 closed on 0 days and runway 29 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.

Instrument approaches to runway 11/29

Methodology and sources

Active runwaysare read from the airport's D-ATIS text (community relay of the FAA broadcast) with an open, tested parser; the broadcast text is always shown. Every change is recorded, so “recorded use” is what the facility stated, never an inference.
Wind components use the current METAR (aviationweather.gov) against TRUE runway headings from the OurAirports/FAA runway record.
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; climatology through 2025-12-31.
