Frequently asked questions
What runways are available at KUES?
Waukesha County Airport, identifier KUES, has two paved runways. Runway 10/28 is the longer of the pair at 5,849 feet, with a width of 100 feet and a concrete surface. Runway 18/36 measures 3,599 feet long and 75 feet wide, surfaced in asphalt. The 10/28 runway carries lighting infrastructure including a MALSR on runway 10 and REIL on runway 28, supporting a wider range of approach operations than the shorter crosswind runway.
Is jet fuel available at Waukesha County Airport?
Waukesha County Airport, KUES, stocks Jet A along with 100LL and A+ avgas grades. The field operates on an ALL / ALL / ALL attendance schedule, meaning fuel and field attendance are not limited to specific days or hours of the year. This makes KUES a viable fuel stop for business aviation traffic operating in the Milwaukee area. Dispatchers should still confirm current fuel status directly with the field before planning a stop, since attendance schedule does not guarantee uninterrupted supply.
Where is the nearest customs facility to KUES?
Waukesha County Airport does not have onsite customs processing. The nearest customs-equipped airport is General Mitchell International, listed under ICAO code KMKE, located approximately 15.96 nautical miles away. Flight crews requiring customs clearance near Waukesha County Airport need to route through that facility instead. This distance should factor into routing and timing decisions for any international arrival planning to use KUES as the final destination.
What happens at KUES when the tower is closed?
When the control tower at Waukesha County Airport, KUES, is closed, pilots are instructed to contact Milwaukee Clearance Delivery on frequency 128.7 for clearance service. This applies only during the specific window when the KUES tower is not operating. Outside of that closure period, clearance delivery is handled locally through the Waukesha tower itself. Crews operating into or out of KUES during off-hours should have the Milwaukee frequency ready as a backup contact point.
Does KUES see seasonal variation in business aviation traffic?
Yes, Waukesha County Airport shows a concentration of business aviation activity in the warmer months. Based on FAA TFMSC traffic data for 2025, monthly operations climb from a low near 589 in February to a peak of 985 in October, with the strongest months running from May through October. Winter months, particularly January and February, see noticeably lower operational counts. Dispatchers scheduling flexible trips into KUES may find more capacity available during the colder part of the year.
