Runway	Pattern	Heading	Pattern altitude
04	Left traffic	040° mag	1,600 ft MSL (≈1,000 AGL)
22	Right traffic	220° mag	1,600 ft MSL (≈1,000 AGL)

No pattern altitude is published for KAPT; 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 KAPT

Marion County Airport - Brown Field 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.

Watch the right traffic ends here: 22. A right pattern at a field where the other end is left is the single most common place to end up pointing at opposing traffic. The full entry procedure is here →
