E79 field & runways
Sierra Sky Park, Fresno, California. Field elevation 321 ft. Non-towered (NON-ATCT). Magnetic variation 15.0°E on record, 12.2°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 0.086°/year west — about 1° every 12 years — which is why runway numbers eventually stop matching their pavement.
