Traffic pattern
Pattern altitude is not published. For light piston operations, use the standard 1,000 ft AGL assumption unless ATC or the current FAA Chart Supplement says otherwise. The field elevation is 261.2 ft MSL, so that puts a reference pattern altitude near 1,261 ft MSL. Tower control is in effect from 0600 to 2000. ATC sequences the pattern during those hours.
Right traffic is published for runway 12. Right traffic is also published for runway 02. Plan for that on arrival and departure. Runway 30 and runway 20 do not have right-traffic notes in the facts.
Every end, one page
Each runway end has its own page with wind component, traffic pattern geometry and ILS for that specific direction.
