Frequently asked

What is the traffic pattern altitude at KLWS?

Lewiston Nez Perce 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 2,400 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 KLWS have right traffic?

Yes, on 2 runway ends: 08, 12. Every other end at Lewiston Nez Perce County Airport is standard left traffic.

Do I fly a standard pattern at KLWS?

Lewiston Nez Perce County Airport is towered (119.4), so the pattern shown here is the charted default — but the controller's instruction overrides it. Expect straight in approaches, base entries and midfield crossings as traffic dictates.

More about KLWS

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.
