Traffic pattern
Pattern altitude is not published. For light piston operations, use the standard 1,000 ft AGL unless local procedure or ATC says otherwise. The field is uncontrolled, so pilots self-announce and self-sequence. Runway 10 has right traffic. Runway 28 is not listed with a traffic pattern exception in the facts. No tower is on site, so there is no ATC sequencing in the pattern. Keep a close eye on traffic flow when joining or departing.
Every end, one page
Each runway end has its own page with wind component, traffic pattern geometry and ILS for that specific direction.
