UNKNOWN

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. Wind calm — no directional preference.

KNKX field & runways

Miramar MCAS (Joe Foss Fld), San Diego, California. Field elevation 477 ft. Class B airspace. Towered. Private use. Magnetic variation 12.0°E on record, 10.9°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 0.075°/year west — about 1° every 13 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	Notes
24L	255.3°	244.5°	matches rule gives runway 25 in ~7 yr	8,001 ft	PEM
24R	255.3°	244.5°	matches rule gives runway 25 in ~7 yr	12,000 ft	CONC	ILS
6L	75.3°	64.5°	matches rule gives runway 7 in ~7 yr	12,000 ft	CONC
