Frequently asked questions
Does KSIV have on-site customs clearance?
KSIV does not have on-site customs facilities. Operators arriving from international destinations must clear customs at Indianapolis International Airport (KIND), located approximately 64.6 nautical miles away, before or after landing at Sullivan County. Flight crews should plan routing accordingly, since Sullivan County itself is not a designated port of entry.
What runway is available at Sullivan County Airport?
Sullivan County Airport has a single paved runway, 18/36, measuring 4,359 feet long and 75 feet wide with an asphalt surface. This is the only runway serving the field, so wind conditions favoring a crosswind runway are not an option at KSIV. The runway length accommodates most light business aircraft operating into the field.
Are the runway lights pilot-controlled at KSIV?
Yes, at Sullivan County Airport (KSIV) the REILs on runways 18 and 36 and the MIRL on runway 18/36 are activated via CTAF, since the field is non-towered. The PAPI systems on both runway ends operate continuously rather than being pilot-activated. Pilots should confirm CTAF frequency procedures before arrival in low-light conditions.
What is the typical fuel availability at KSIV?
Sullivan County Airport stocks both 100LL avgas and Jet A fuel, supporting piston and turbine business aircraft. The airport is attended Monday through Saturday from 0800 to 1700 and Sunday from 1300 to 1700, which governs the hours fuel service is available. Operators arriving outside those windows should plan fuel needs in advance, as KSIV is a lower-traffic field.
