Frequently asked questions
What runways are available at KFLD?
Fond du Lac County Airport, identifier KFLD, operates two paved asphalt runways. Runway 18/36 is the primary strip at 5,941 feet long and 100 feet wide, supporting the majority of business aviation traffic. Runway 09/27 measures 3,604 feet long and 75 feet wide, offering a crosswind option. Both runways are paved and suitable for turbine and piston traffic within their respective length limits. Lighting includes HIRL on 18/36 and MIRL on 09/27, both controlled through CTAF.
Is KFLD a towered airport?
Fond du Lac County Airport is non-towered, so arriving and departing traffic self-announces on the common frequency. The airport is attended daily from 0800 to 1800 local time. Pilots unable to reach flight service on the FSS frequency are directed to contact Chicago ARTCC instead. Runway and approach lighting, including MALSR on runway 36 and REIL on runway 18, are pilot-controlled through CTAF. Dispatchers should plan communications accordingly given the absence of a control tower at KFLD.
Does KFLD have customs clearance on site?
Fond du Lac County Airport does not have customs processing on site. The nearest customs facility is at KSBM, located approximately 27.60 nautical miles away. Flights requiring customs clearance should plan to route through that facility rather than expecting service directly at KFLD. This distance is a meaningful planning factor for any international arrival intending to use Fond du Lac as the port of entry. Confirm current customs procedures at KSBM before filing a flight plan through the region.
What fuel is available at KFLD?
Fond du Lac County Airport stocks both 100LL avgas and Jet A fuel, according to the facility data on file. The airport is attended from 0800 to 1800 local time daily, which aligns with the hours fuel service can typically be arranged. Business aviation traffic at KFLD, which accounted for the large majority of the airport's 2,305 annual operations in 2025 per FAA TFMSC data, relies on this dual fuel availability. Confirm fuel service hours directly given the airport's non-towered, attended-hours operating model.
What obstacles should pilots be aware of near KFLD?
Fond du Lac County Airport has a close-in obstruction on file: a 7-foot building located 180 feet from the runway end and 440 feet left of centerline. Separately, the airport reports a centerline obstruction that exceeds a 45-degree slope from the runway. Both factors are relevant to departure and approach planning at KFLD, particularly for operators flying tighter obstacle clearance margins. Crews should review current published obstacle data before operating into or out of the airport. These remarks reflect conditions reported in the airport's official remark data.
