Pattern direction by runway

Runway	Pattern	Heading	Pattern altitude
12	Left traffic	119° mag	1,100 ft MSL (≈1,000 AGL)
30	Left traffic	299° mag	1,100 ft MSL (≈1,000 AGL)

No pattern altitude is published for 09A; the figure above is the AC 90-66B 1,000 ft AGL convention for propeller aircraft, rounded to the field. Turbine aircraft normally fly 1,500 ft AGL. Headings are the runway alignment; downwind is the reciprocal.

Flying the pattern at 09A

Butler/Choctaw County is non towered, so the pattern is self announced on CTAF 122.8. AC 90-66B asks for a report on entry and on each leg, and for the standard 45° entry to downwind at pattern altitude.

All ends are left traffic, which is the FAR 91.126 default — turns to the left unless the field charts otherwise. The full entry procedure is here →

Frequently asked

What is the traffic pattern altitude at 09A?

Butler/Choctaw County has no traffic pattern altitude published in the FAA NASR data. The AC 90-66B convention for propeller aircraft is 1,000 ft AGL, which works out to roughly 1,100 ft MSL (≈1,000 AGL) here — but confirm it against the Chart Supplement before you fly, since a field can have a non standard pattern altitude that NASR does not carry.

Does 09A have right traffic?

No. All 2 runway ends at Butler/Choctaw County use standard left traffic, so no right pattern is charted here.

What frequency is the pattern on at 09A?

Butler/Choctaw County is non towered, so pattern position reports go on the CTAF, 122.8. AC 90-66B asks for self announcing on entry and on each leg.

More about 09A

Pattern direction and alignment are drawn from the FAA NASR (28-day cycle); the diagram is generated, not an FAA chart. Pattern altitude is shown as published where NASR carries one, otherwise as the AC 90-66B 1,000 ft AGL convention. For planning and education only; always verify against the Chart Supplement.
