Frequently asked

What is the traffic pattern altitude at KSUX?

Sioux Gateway Airport / Brigadier General Bud Day 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 2,100 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 KSUX have right traffic?

No. All 4 runway ends at Sioux Gateway Airport / Brigadier General Bud Day Field use standard left traffic, so no right pattern is charted here.

Do I fly a standard pattern at KSUX?

Sioux Gateway Airport / Brigadier General Bud Day Field is towered (118.7), 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.

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.
