Traffic pattern
Pattern altitude is not published. For light piston operations, use the standard 1,000 ft AGL pattern unless local procedures say otherwise. That puts the pattern near 3,110 ft MSL at this field elevation. No right-traffic exceptions are published. No tower is published, so self-announced sequencing applies in the pattern. Check the current FAA Chart Supplement before flight for any updates or local notes.
Every end, one page
