CO90 field & runways
USAF Academy Bullseye Aux Airfield, Ellicott, Colorado. Field elevation 6036 ft. Non-towered (NON-ATCT). Private use. Magnetic variation 11.0°E on record, 7.0°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 0.079°/year west — about 1° every 13 years — which is why runway numbers eventually stop matching their pavement.
