Frequently asked questions
Is fuel available at KDYB Summerville Airport?

There is no control tower at Summerville, so arrivals should coordinate fuel needs against the posted attendance hours. Operators planning arrivals outside those windows should account for the field's unattended status when scheduling fuel uptake.
What runway does Summerville Airport (KDYB) offer?
Summerville Airport, KDYB, has a single asphalt runway, 06/24, measuring 5,000 feet long and 75 feet wide. This is the airport's only paved surface, and its length matches the field's listed maximum paved runway length. The runway lighting, MIRL, operates from dusk until 2200 local, with pilot-controlled activation available afterward through CTAF. KDYB is non-towered, so all runway operations rely on self-announced procedures.
Does KDYB have on-airport customs clearance?
Summerville Airport, KDYB, does not have customs service on the field itself. The nearest customs facility is at KCHS, Charleston, located approximately 15.59 nautical miles away. Operators requiring customs clearance need to route through KCHS or another designated port of entry rather than clearing directly at KDYB. This distance should be factored into ground transportation or repositioning plans for any international arrival requiring inspection.
Is there noteworthy seasonal traffic variation at KDYB?
Yes, business aviation traffic at KDYB, Summerville Airport, shows a concentration in early winter months according to FAA TFMSC data. January logs the highest monthly count at 132 operations, well above the yearly average, while March sits at the annual low with 74 operations. The gap between the busiest and quietest months is significant relative to the roughly 1,226 annual business aviation operations recorded for 2025. Dispatchers scheduling around this field should note the January peak when planning slot or parking expectations.
What ground activity should pilots be aware of near KDYB's runway?
Summerville Airport, KDYB, reports intermittent banner towing operations below 1500 feet on the south side of runway 06/24, occurring daily. Mowing operations also take place near active runways and taxiways on Wednesdays during the growing season. Both activities occur on or near the airport's single paved runway, 06/24, which is the field's only movement surface. Pilots operating at this non-towered airport should monitor CTAF closely given these recurring ground and low-altitude activities.
