Pattern direction by runway

Runway	Pattern	Heading	Pattern altitude
10	Right traffic	101° mag	3,100 ft MSL (≈1,000 AGL)
28	Left traffic	281° mag	3,100 ft MSL (≈1,000 AGL)

No pattern altitude is published for KNXP; 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 KNXP

Twentynine Palms Strategic Expeditionary Landing Field is non towered. 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: 10. 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 →

Frequently asked

What is the traffic pattern altitude at KNXP?

Twentynine Palms Strategic Expeditionary Landing Field 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 3,100 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 KNXP have right traffic?

Yes, on one runway end: 10. Every other end at Twentynine Palms Strategic Expeditionary Landing Field is standard left traffic.

More about KNXP

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.
