Runway 20 — weak lean on available evidence

The answer is 20 with a 7 kt tailwind from the reported wind — the observation is 1583 min old, so the wind may have shifted or the flow has not been changed yet. No D-ATIS feed here — a voice ATIS/AWOS may exist; check the frequency. No ADS-B traffic data available. Weather observation is 1583 minutes old — treat with caution.

KMGY field & runways

Dayton/Wright Brothers, Dayton, Ohio. Field elevation 957 ft. Non-towered (NON-ATCT). Magnetic variation 4.0°W on record, 6.4°W today.

The FAA's variation of record is the number this field was surveyed against; the second is where north points now, from WMM2025. It is moving 0.026°/year west — about 1° every 38 years — which is why runway numbers eventually stop matching their pavement.

Runway data from the FAA NASR 01 Oct 2026 cycle. Where NASR locates both thresholds, the true heading is the bearing between them rather than NASR's whole-degree alignment. Magnetic is that heading against today's declination from WMM2025, not the field's variation of record — so it can differ from the chart by the gap between the two shown above. The number painted on the runway is the one ATC uses.
