Frequently asked questions
What runways does KISW offer for business aircraft?
Alexander Field South Wood County, identified as KISW, has three runways. Runway 02/20 is the primary paved surface at 5,500 feet long and 100 feet wide, asphalt construction. Runway 12/30 offers a shorter paved option at 3,472 feet by 60 feet, also asphalt. A third runway, 18/36, is a 2,089-foot turf strip suited to lighter traffic. The 5,500-foot runway is the field's longest paved surface and the one most relevant for turbine business aircraft.
Is fuel available at KISW outside staffed hours?
Yes, KISW offers 24-hour self-service fuel with credit card payment, according to airport remarks. The field stocks 100LL avgas along with Jet A and Jet A+ turbine fuel. Staffed attendance runs all days from 0700 to 1700 local time, but the self-service option covers hours outside that window. This makes the field usable for after-hours fuel stops without requiring line service coordination. No third-party fuel provider is named in the airport's operational data.
Does KISW have on-site customs clearance?
No, Alexander Field South Wood County does not have on-site customs service. The nearest customs-capable airport is KATW, located approximately 57 nautical miles away. Flights requiring customs clearance need to route through KATW or another designated port of entry rather than clearing directly at KISW. Dispatchers planning international arrivals should factor this distance into routing and timing decisions. No CANPASS or restricted-access customs arrangement is indicated for this field.
How busy is KISW and when does traffic peak?
KISW recorded 1,232 total annual operations in 2025 per FAA TFMSC data, with business aviation accounting for 1,001 of those operations. Traffic is concentrated in the summer months, with June and July each exceeding 190 business aviation operations. By contrast, November and December see minimal activity, dropping to single digits and the high teens. This seasonal pattern suggests the field sees its heaviest use during the warmer months. The airport is classified as a Tier 1 facility within Skystar's traffic categorization.
What lighting is available at KISW for night or low-visibility operations?
Alexander Field South Wood County provides runway edge lighting on both paved runways, with MIRL on Runway 02/20 preset to low intensity from sunset to sunrise. Pilots can increase intensity and activate REIL on Runways 02 and 20, along with PAPI on Runways 02, 20, and 30, via radio control. Runway 12/30 also has MIRL controllable through the common traffic advisory frequency. KISW is a non-towered field, so all lighting activation is pilot-controlled rather than tower-directed. No lighting is indicated for the turf Runway 18/36.
