No ILS approaches are published here. Plan for non-precision or visual work only. Verify current approach options in the FAA Chart Supplement before you go. JW Aviation is on the field. It carries AVGAS 100LL, JET A, PRIST and MOGAS.

The published remarks matter here. Use runway 18 in calm wind or direct crosswinds. Full stop landings only. No touch-and-goes. Traffic patterns south of the airport should stay within three quarters of a mile. Wildlife is reported on and near the airport, so keep your scan active on taxi and final. The runway lights are preset low from dusk to dawn. They then increase intensity on CTAF.

This is a small, busy local field with a narrow taxiway. Large aircraft should think ahead on taxi and may need to back-taxi. For clearance delivery, Chicago Approach is the published contact. If you need the latest noise or operational notes before departure, check the current FAA Chart Supplement or call the airport operator directly.
