Overview

Frequently asked questions
What runway options are available at KOOA?
KOOA offers two paved concrete runways: 13/31 at 4,012 feet by 75 feet, and 04/22 at 1,926 feet by 75 feet. The longer 13/31 runway is the primary option for business aircraft, given its greater length. Both runways are paved, providing consistent surface conditions for arriving and departing traffic at Oskaloosa Municipal Airport.
Is Oskaloosa Municipal Airport towered?
Oskaloosa Municipal Airport (KOOA) is a non-towered field, meaning pilots coordinate their own traffic pattern and communications on CTAF. Runway lighting, including the MIRL and REIL systems on runway 13/31, is pilot-activated through CTAF rather than controlled by ground personnel. Clearance delivery for the field is handled through Chicago ARTCC rather than a local tower.</answer_placeholder
What are the attendance hours at KOOA?
KOOA is staffed Monday through Friday, 0800-1800 local during May through September, and 0800-1700 local during October through April. On weekends, the airport operates on an on-call basis rather than fixed hours. Outside these windows, pilots should expect an unattended field with self-service procedures for lighting and communications.
Where is the nearest customs facility to KOOA?
The nearest customs-capable airport to Oskaloosa Municipal Airport is Des Moines International (KDSM), located approximately 55.82 nautical miles away. KOOA itself does not have onsite customs processing, so international arrivals must route through KDSM or another designated port of entry. Dispatchers planning international legs should factor this distance into routing decisions.
