Frequently asked questions
What runways are available at KVYS?
Illinois Valley Regional-Walter A Duncan Field, KVYS, operates two paved asphalt runways. Runway 18/36 is the primary strip at 5,999 feet long and 100 feet wide. Runway 07/25 offers a secondary option at 3,999 feet long and 75 feet wide. Both runways support the airport's business aviation traffic, which totals 1,038 annual operations. Neither runway is served by a control tower, since KVYS operates as a non-towered field.
Is there a control tower at KVYS?
KVYS is a non-towered airport, so there is no local tower controlling arrivals and departures. Traffic coordination relies on the common traffic advisory frequency, which also controls runway lighting intensity for runway 18/36 and activates the REIL system on runway 07/25. Clearance delivery is handled remotely, with pilots directed to contact Chicago ARTCC for that service. This setup is typical for a field of this size and traffic volume.
