KDTW Runway 03L/21R — Detroit Metropolitan Wayne County Airport

Oct 28, 2026 (airport-local day): 0 configuration changes since local midnight, from the D-ATIS broadcasts 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 D-ATIS use since Sep 18, 2026 (720 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 0902Z (5:02 AM EDT).

Published NASR record; does not reflect temporary closures or restrictions. Current operational status is the card at the top of the page.

Runway 03L/21R 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, 7.0°W (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.

Runway percentages are measured independently. Multiple runways can be active simultaneously, so totals may exceed 100%.

Observed runway usage — 720 hours of D-ATIS runway configuration history collected · 59 distinct configurations observed · 1,988 D-ATIS broadcasts recorded · through Oct 28, 2026. Shares are the fraction of recorded hours in which the D-ATIS named each end. Wind sectors use the wind reported when each configuration began. Nothing here is inferred from wind; the wind-favored analysis for KDTW is a separate module. 90-day, 12-month and seasonal views appear once the record is long enough.
