Frequently asked questions
What runways are available at KSSF?
Stinson Municipal, identifier KSSF, operates two paved asphalt runways. Runway 10/28 is the longer of the two at 5,000 feet by 100 feet wide. Runway 14/32 measures 4,128 feet by 100 feet wide. Both surfaces support the fuel types available on field, which include 100LL and Jet A. The airport's tower and lighting setup work with either runway depending on traffic flow and wind.
Is fuel available at KSSF, and what type?
Stinson Municipal carries both 100LL avgas and Jet A fuel on field, as confirmed in airport data. The facility is a towered public-use airport in San Antonio, Texas, with an elevation of 578 feet. Attendance runs seven days a week from 0700 to 2000 local time. Outside that window, pilots should expect reduced or unattended services. Business aviation traffic through KSSF averaged roughly 73 operations per month in 2025 according to FAA TFMSC data, so fuel demand exists across the full operating schedule.
Does KSSF have on-site customs clearance?
Stinson Municipal does not have customs service on site. The nearest customs-capable airport is Kelly Field, located 6.42 nautical miles away. Pilots arriving from international origins need to route through that facility or another designated port of entry before or after operating at KSSF. San Antonio International, another nearby field, sits roughly 11.83 nautical miles to the north. Flight planning for any international leg should account for this gap in on-field customs capability.
What obstacle clearance issues affect approaches at KSSF?
Stinson Municipal has published approach slope data reflecting close-in terrain and vegetation near its runway thresholds. One approach slope is 25:1 clearing 61-foot trees at a distance of 1,585 feet to the displaced threshold. Another is 22:1 over 50-foot trees at 1,100 feet, and a third is 24:1 over 35-foot trees at 835 feet. Fencing and roadways close to the runway ends are also noted in airport remarks, with clearances as tight as zero feet distance in some spots. Crews should review these figures carefully during approach and departure planning at KSSF.
When does business aviation traffic peak at Stinson Municipal?
Business aviation traffic at Stinson Municipal, KSSF, is concentrated in specific months rather than spread evenly across the year. April 2025 logged 174 business aviation operations, well above every other month, according to FAA TFMSC data. February and October followed with 86 and 87 operations respectively. The quietest months were June and May, with 44 and 55 operations. Dispatchers scheduling flights into KSSF during peak months should anticipate busier ramp and traffic patterns than the annual average of 881 bizav operations would suggest on its own.
