KTTD field & runways
Portland-Troutdale, Portland, Oregon. Field elevation 39 ft. Class D airspace. Towered. Magnetic variation 16.0°E on record, 14.4°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 0.116°/year west — about 1° every 9 years — which is why runway numbers eventually stop matching their pavement.
