Frequently asked questions
What runways are available at KGNC?
Gaines County Airport (KGNC) has two paved asphalt runways. Runway 08/26 is the longer of the two at 5,381 feet by 75 feet wide, and also represents the airport's maximum paved runway length. Runway 17/35 measures 5,002 feet by 75 feet, also asphalt. Both runways are equipped with medium intensity runway lights (MIRL) that are preset to low intensity, with pilot-controlled step-up available on CTAF. Neither runway length supports the largest cabin-class jets, but both accommodate typical turboprop and light-to-midsize jet traffic.
Is fuel available at Gaines County Airport?
Gaines County Airport (KGNC) offers both 100LL and Jet A fuel. This dual availability supports mixed piston, turboprop, and jet traffic operating in the area. The airport's attendance schedule runs Monday through Friday from 0800 to 1800, and Saturday from 0800 to 1200, which governs when fuel service and other staffed functions are typically available. Operators planning arrivals outside these windows should account for the lack of staffed attendance during those hours.
Does KGNC have customs clearance on site?
Gaines County Airport (KGNC) does not have customs service on site. The nearest customs facility is at Midland International Air and Space Port (KMAF), located approximately 49.59 nautical miles away. Operators arriving from international origins need to plan a stop at KMAF or another customs-equipped airport before or after using KGNC. This distance should be factored into routing and fuel planning for any flight requiring customs clearance.
How busy is Gaines County Airport and what type of traffic dominates?
Gaines County Airport (KGNC) logged 1,341 total annual operations in 2025 according to FAA TFMSC data, of which 1,191 were business aviation operations. This means business aviation makes up nearly the entirety of recorded traffic at the field. Monthly business aviation operations ranged from a low of 71 in February to a high of 122 in May. The airport's ops tier classification places it among Skystar's most active and best-documented general aviation fields in this dataset.
What operational conditions should pilots be aware of at KGNC?
Gaines County Airport (KGNC) has faded runway markings, according to current airport remarks, so pilots should not rely solely on visual paint markings for runway identification or centerline guidance. Runway lighting on both 08/26 and 17/35 is preset to low intensity and requires activation via CTAF to increase brightness. For clearance delivery, pilots should contact Fort Worth ARTCC rather than a tower or local FBO frequency, since the field is non-towered. These factors combine to require extra attention during low-light or night operations.
