PAPK field & runways

Napaskiak, Napaskiak, Alaska. Field elevation 11 ft. Non-towered (NON-ATCT). Magnetic variation 15.0°E on record, 9.1°E 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 0.279°/year west — about 1° every 4 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.
Runway	True	Magnetic	Number	Length	Surface	Pattern	Notes
2	30.7°	21.6°	matches rule gives runway 3 in ~12 yr	3,000 ft	GRVL	left
20	210.7°	201.6°	matches rule gives runway 21 in ~12 yr	3,000 ft	GRVL	left
