No runway-in-use estimate is possible here

The FAA's NASR data publishes no runway alignment for this field, so there is nothing to compute a wind component against and no way to tell which end an aircraft used. What is known about the field is below.

We don't know, and saying so beats guessing. No D-ATIS feed here — a voice ATIS/AWOS may exist; check the frequency. No ADS-B traffic data available. No weather observation available.

1B2 field & runways

Katama Airpark, Edgartown, Massachusetts. Field elevation 18 ft. Non-towered (NON-ATCT). Magnetic variation 16.0°W on record, 13.9°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 0.066°/year east — about 1° every 15 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.
