Unknown — not enough evidence to call a runway

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. Weather observation is 10014 minutes old — treat with caution.

KNHK field & runways

Patuxent River NAS (Trapnell Fld), Patuxent River, Maryland. Field elevation 39 ft. Class D airspace. Non-towered (ATCT-RATCF). Private use. Magnetic variation 10.0°W on record, 10.9°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 0.007°/year east — about 1° every 143 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.
