KONT field & runways

Ontario Intl, Ontario, California. Field elevation 944 ft. Class C airspace. Towered. Magnetic variation 12.0°E on record, 11.2°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 0.078°/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	Pattern	Notes
26L	270.0°	258.8°	matches	10,200 ft	CONC	left	ILS
26R	270.0°	258.8°	matches	12,197 ft	CONC	right	ILS
8L	90.0°	78.8°	matches	12,197 ft	CONC		ILS
