Frequently asked questions
What is the longest runway at KSUA?
Witham Field's longest runway is Runway 12/30, at 5,828 feet with a 100-foot width and asphalt surface. Two additional paved runways serve KSUA: Runway 16/34 at 5,000 feet and Runway 07/25 at 4,653 feet, both also 100 feet wide. Runway 12/30 has an EMAS installation at both departure ends, 502 feet long at the Runway 12 end and 413 feet long at the Runway 30 end. The airport is towered, with an attendance schedule spanning 0600 to 2200 daily.
Does KSUA have customs available for international arrivals?
Yes, Witham Field has CBP inspection services available onsite, along with a USDA compliance agreement covering agricultural inspection needs. This allows aircraft arriving from abroad to clear customs directly at KSUA rather than routing to another facility. Dispatchers should still confirm specific procedural requirements ahead of arrival, since onsite service does not eliminate the need for advance coordination. Witham Field is a public, towered airport in Stuart, Florida, and traffic here is dominated by business aviation.
Are touch-and-go operations allowed at Witham Field?
Touch-and-go operations are permitted at Witham Field Monday through Saturday, from 0900 until two hours past sunset, with exceptions on New Year's Day, Christmas, and Thanksgiving. Each pilot is limited to three such operations per day. Separately, stop-and-go operations and intersection takeoffs are strongly discouraged at all times at KSUA. Stage 1 and Stage 2 jet operations are also strongly discouraged between 2300 and 0800. These procedures reflect noise sensitivity in all quadrants surrounding the airport.
What is the seasonal traffic pattern at KSUA?
Business aviation traffic at Witham Field concentrates heavily in the winter months, according to FAA TFMSC data for 2025. December, March, and February show the highest monthly figures, each above 4,000 operations, while June through September drop to roughly 1,300 to 1,600 operations per month. Annual business aviation operations at KSUA total 34,273 out of 40,579 overall operations recorded for the year. This seasonal swing reflects the typical winter influx seen at Florida general aviation airports serving the Stuart area.
Are there wingspan or approach restrictions pilots should know about at KSUA?
Aircraft with wingspans exceeding 79 feet are prohibited from operating on Taxiway A between Taxiway C and the approach end of Runway 12 whenever another aircraft with a wingspan over 79 feet is approaching, landing, or departing on Runway 12/30. Separately, the PAPI on Runway 25 is restricted to 7.5 nautical miles west of the runway because of towers reaching 1,548 feet MSL within 10 degrees of the extended centerline. Runway 34 also has close-in obstructions: 22-foot trees and an 8-foot fence positioned 200 feet from the runway end and 150 feet left. Pilots operating larger aircraft at Witham Field should account for these constraints during planning.
