Frequently asked questions
What runway does KSLR offer?
Sulphur Springs Municipal Airport, identifier KSLR, operates a single runway, 01/19, built with a concrete surface. It measures 5,001 feet long and 75 feet wide, sufficient for most business jet traffic. The airport has no operating control tower, so pilots coordinate movements on CTAF. Close-in obstructions near both runway ends are documented in the airport remarks, including a fence, brush, and a building along the approach path. Dispatchers planning operations at KSLR should review those obstruction distances alongside runway length when calculating performance margins.
Is fuel available at KSLR?
Sulphur Springs Municipal Airport lists both 100LL and Jet A among its fuel types. According to the airport remarks, 100LL is available 24 hours through a self-serve facility. The attendance schedule shows staffed hours Monday through Saturday from 0800 to 1800, with Sunday service available by request. Jet A availability is noted in the airport data, though the self-serve remark applies specifically to 100LL. Dispatchers should confirm Jet A service arrangements ahead of arrival given the limited staffed hours.
Does KSLR have customs clearance onsite?
Sulphur Springs Municipal Airport does not have customs clearance onsite. The nearest customs-equipped airport is KTKI, located approximately 48.64 nautical miles away. Flights requiring federal inspection services need to route through that facility instead of clearing directly at Sulphur Springs. This is a standard arrangement for airports of this size and traffic profile. Dispatchers arranging international arrivals should factor this distance into routing and ground transportation planning.
What lighting is available for night operations at KSLR?
Sulphur Springs Municipal Airport, KSLR, has medium intensity runway lighting on runway 01/19 that is preset to low intensity from dusk to dawn. Pilots can increase intensity and activate the runway end identifier lights on both runways 01 and 19 through CTAF. Precision approach path indicators serve both runway ends and operate continuously rather than on pilot-activated timing. One remark notes the PAPI is unusable beyond 8 degrees right of runway centerline, a detail relevant to approach planning. This combination supports night arrivals at an airport without a control tower.
How much business aviation traffic does KSLR see, and is it seasonal?
Sulphur Springs Municipal Airport recorded 625 business aviation operations in 2025 out of 1,354 total annual operations, according to FAA TFMSC data. Monthly figures show meaningful variation across the year, with October posting the highest count at 86 operations and April the lowest at 30. Traffic builds through the fall months, peaking in October before tapering into December. This pattern is worth noting for dispatchers scheduling maintenance windows or planning around slower periods. KSLR carries an ops tier 1 classification within the Skystar registry, reflecting its documented traffic volume.
