Audubon County Airport (KADU) sits in Audubon, Iowa. The field elevation is 1,287.7 ft MSL. It has one runway. Runway 14/32 is 3,641 ft long with a concrete surface. There is no control tower. No ILS approaches are published here.

The pattern altitude is not published. Use the standard 1,000 ft AGL for light piston operations unless the current Chart Supplement says otherwise. That puts the pattern at about 2,287.7 ft MSL based on the listed field elevation. CTAF and UNICOM are both listed as 122.8. The published remarks say CTAF is out of service indefinitely. Check the current Chart Supplement and contact the airport operator before you go.

Published remarks also note a 64-foot lighted pole 1,200 feet from the threshold on the left side of runway 14. The runway 14 approach slope is 32 to 1 to the displaced threshold. Medium intensity runway lights, PAPI and REIL on both ends are activated by CTAF. The rotating beacon is out of service indefinitely. There are no on-field FBOs listed. For clearance delivery, contact Minneapolis ARTCC at 651-463-5588. Pilots should plan for a non-towered arrival with no published ILS and review the current Chart Supplement before flying in.
