KNRB field & runways
Mayport Ns (Adm David L Mcdonald Fld), Mayport, Florida. Field elevation 15 ft. Class D airspace. Towered. Private use. Magnetic variation 6.0°W on record, 7.2°W 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 0.065°/year west — about 1° every 15 years — which is why runway numbers eventually stop matching their pavement.
| Runway | True | Magnetic | Number | Length | Surface | Pattern | Notes |
|---|---|---|---|---|---|---|---|
| 23 | 222.8° | 229.9° | matches | 8,001 ft | ASPH | right | |
| 5 | 42.8° | 49.9° | matches | 8,001 ft | ASPH |
