No pattern altitude is published for KACV; 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 KACV

California Redwood Coast-Humboldt County Airport is non towered, so the pattern is self announced on CTAF 123.0. 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: 19, 14. 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 KACV?

California Redwood Coast-Humboldt County Airport 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 1,200 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 KACV have right traffic?

Yes, on 2 runway ends: 19, 14. Every other end at California Redwood Coast-Humboldt County Airport is standard left traffic.

What frequency is the pattern on at KACV?

California Redwood Coast-Humboldt County Airport is non towered, so pattern position reports go on the CTAF, 123.0. AC 90-66B asks for self announcing on entry and on each leg.

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.
