Waukesha County is a large general aviation airport located just north of the city of Waukesha, Wisconsin. It is also 15 miles northwest of the larger Milwaukee Mitchell International Airport (MKE) and the city of Milwaukee. The primary runway 10-28 is intersected by the smaller runway 18-36. The taxiway system provides access to all facilities and services found in all quadrants except for the northwest. The traffic mix consists of a spectrum of general and business aviation. There is also a busy helicopter community, including the occasional military helo. There are several flight schools located on the airport providing basic flight training up through advanced ratings.

Waukesha has class Delta airspace with a cutout to the northeast to accommodate traffic arriving and departing Capitol Drive (02C) airport. Use extra vigilance when arriving to UES from this direction. Another arrival issue has to do with misidentification of runway 18 and taxiway Bravo. Perhaps due to the different color surfaces, pilots have mistakenly lined up on the taxiway rather than the runway.
