Pattern altitude: 1,015 ft MSL (1,000 ft AGL). Verify pattern direction and altitude with the chart supplement before flying. // On calm winds (<3 kt), all runways are usable — favor the longest or whatever the pattern calls for.

// Density altitude

Density altitude needs current temperature + altimeter + field elevation — one or more is unavailable for KNRB.
