The Brodhead Airport carries FAA designator C37 and while it is privately owned, it is open to the public and carries no landing restrictions. Its three grass runways are symbolized on the Chicago sectional chart with an open circle. It is in uncontrolled, or class G airspace, underlying class E, the least restrictive of controlled airspace.  The nearest airspace requiring radio contact is the Janesville (JVL) class D about 10 miles east of Brodhead. The Madison (MSN) class C airspace begins about 30 miles north.

The airport is about 1 mile south of the city Brodhead near the junction of state highways 11 and 81. The nearest hard surface airport is Monroe (EFT) about 11 nm west.  The nearest instrument approach is also at Monroe, while Janesville (JVL) has full ILS capability. Madison (MSN) and Rockford (RFD) both offer radar service in the area.

Brodhead’s airport area is fairly flat with a few trees. The perimeter is mostly surrounded by irrigated fields.  There are no “tall” towers or obstructions that affect the traffic pattern. The 6 runway thresholds are displaced for controlling objects.

Airport elevation is 793 feet. Traffic pattern altitude is 800 feet AGL or 1600 feet MSL. The active runway is dictated by surface winds. During busy times when winds are light or calm runway 27 is considered the active.  During fly-ins check surface markings as other runways may be closed. The Common Traffic Advisory Frequency (CTAF) is 122.9.  Monitor and call your intentions and be vigilant as many aircraft using the field are non-radio equipped. Fly standard left-hand traffic patterns and look for aircraft possibly flying patterns to other runways. Please be predictable near the airport.

The runways are not plowed in winter and the airport is open to ski equipped aircraft.
