Located in the heart of the Sauk Valley, the Whiteside County Airport (SQI) ranks as one of the world's friendliest general aviation airports. Dedicated to noncommercial air travel, SQI averages over several thousand takeoffs and landings annually. SQI has two runways – one with full instrument landing system, a localizer back course, and several global positioning system (GPS) type approaches. The main runway is 6,500 feet in length and the crosswind runway is 3,900 feet long. SQI has a rich history in aviation, hosting many aviation and other events. SQI has even visited by President Ronald Regan, who was born just to the south of Rock Falls, in Tampico, IL.
Our fixed based operator, Sauk Valley Aviation, provides and arranges aircraft storage and parking, aviation fuel, aircraft sales, flight instruction, aircraft charter and aircraft maintenance.
In addition, SQI serves as home to Radio Ranch that provides aviation support activities such as aircraft repairs, avionics and other specialized functions.
SQI is also home to non-profit organizations such as Twin Cities Flying Club and the Sauk Valley Pilots Association, as well as the Whiteside County Civil Air Patrol. Many aviation enthusiasts and pilots participate in these valuable organizations.
The Whiteside County Airport plays a crucial role in the Northern Illinois airport system, serving a variety of private, corporate and government aviation needs. By providing a place for general aviation, which encompasses all flying other than scheduled air carrier service or the military, SQI enhances both safety and efficiency at the region's commercial airports.
Business travelers and tourists using private, corporate and charter aircraft benefit from the airport's convenient proximity to area business, recreation and entertainment venues.
