Frequently asked questions
What are the fuel options at KSXK?
Sioux County Regional (KSXK) offers self-service fuel available H24, with 100LL avgas and A+ fuel listed among its fuel types. Jet A is also available at the field according to airport data. Because fuel is self-service, crews should plan for card-based or self-managed fueling rather than line service. The field has no control tower, so fuel logistics should be coordinated independently of ATC. Attendance hours run Monday through Friday from 0600 to 1800 and Saturday from 0800 to 1200, which is separate from the self-service fuel availability.
Is there a control tower at Sioux County Regional?
Sioux County Regional (KSXK) is a non-towered airport, so arriving and departing traffic self-announces on the common traffic advisory frequency. Lighting systems including the MALSR on runway 35, REIL on runway 17, PAPI on both runway ends, and MIRL on runway 17/35 are pilot-activated through CTAF. For clearance delivery, crews are directed to contact Sioux City ATCT on a separate frequency rather than a local tower. Runway 17/35 is the airport's single paved runway, measuring 5,500 feet long and 100 feet wide with a concrete surface.
How long is the runway at KSXK?
KSXK has one paved runway, designated 17/35, measuring 5,500 feet in length and 100 feet in width with a concrete surface. This is also the maximum paved runway length at the field, meaning no other runway configuration extends beyond this dimension. The runway surface and length support a range of business aviation aircraft using Sioux County Regional. Lighting on this runway includes a MALSR on the runway 35 end, REIL on the runway 17 end, PAPI on both ends, and MIRL along the full runway length, all activated via CTAF.
Does Sioux County Regional have customs service onsite?
Sioux County Regional does not have customs service onsite. The nearest customs facility is at KFSD, located approximately 43.88 nautical miles away. Operators requiring customs clearance need to route through that airport rather than clearing directly at KSXK. This distance should be factored into trip planning for any international arrival requiring a customs stop before or after using Sioux County Regional.
When does business aviation traffic peak at KSXK?
Business aviation traffic at Sioux County Regional (KSXK) shows a seasonal pattern, concentrating in the summer months. According to FAA TFMSC data, June recorded 158 operations and July recorded 155 operations, the two highest months of the year. This compares to the lowest months in the winter, such as January with 96 operations. Total annual business aviation operations for 2025 stood at 1,578 out of 1,778 total operations at the field. Dispatchers scheduling summer trips into KSXK should anticipate this seasonal traffic increase relative to the winter months.
