Frequently asked questions
Does KRWN have customs clearance on the field?
Arens Field (KRWN) does not have customs clearance onsite. The nearest customs-capable airport is KSBN, located approximately 39 nautical miles away. Operators requiring customs processing should coordinate arrival through KSBN rather than expecting service at Winamac. This distance should factor into routing and fuel planning for international arrivals.
What fuel is available at Arens Field?
Arens Field (KRWN) offers both 100LL avgas and Jet A, though both are self-service only. There is no attended fuel desk, so pilots should be prepared to handle fueling independently. The airport's attendance schedule runs weekdays from 0900 to 1700, which may affect availability of any on-field support outside those hours.
How long is the runway at KRWN?
KRWN has a single asphalt runway, 09/27, measuring 4,201 feet in length and 75 feet wide. A 300-foot stopway extends off the west end of the runway. The runway also has a 35:1 clearance slope to a displaced threshold, which operators should factor into approach planning at Arens Field.
Is Arens Field towered, and how is clearance delivery handled?
Arens Field (KRWN) is a non-towered airport. Pilots needing clearance delivery should contact South Bend Approach; if South Bend Approach is closed, Chicago ARTCC handles clearance delivery instead. Runway lighting, including REIL and PAPI on both runway ends and MIRL on 09/27, is pilot-activated via CTAF.
