Airport Overview
Appleton International Airport (KATW) is a commercial-service airport located in Greenville, Wisconsin, 3 nautical miles west of downtown Appleton and roughly 30 miles south of Green Bay. Owned and operated by Outagamie County, it serves the Fox Valley region and ranks as the third-busiest of Wisconsin's commercial airports, handling well over a million passengers annually across carriers including Allegiant, American, Delta, Sun Country, and United. For private aviation it offers full FBO support, a control tower, and instrument approaches in an uncongested environment.
Runway Capability
The main runway, 03/21, is 8,002 feet of grooved concrete and accommodates the full spectrum of business jets without restriction, including super-midsize and large-cabin types such as the Gulfstream G650 and Bombardier Global. The 6,501-foot crosswind runway, 12/30, provides excellent alignment options in shifting winds. Both runways are 150 feet wide. There is no weight limit, noise curfew, or slot restriction, and the airport operates 24/7.
Charter Considerations
KATW is a practical jet gateway for the Fox Valley, Lake Winnebago, and southern Green Bay markets. The Appleton Flight Center FBO provides Jet-A, hangar space, de-icing, and crew/passenger amenities, while a large Gulfstream Aerospace service center on the field reflects substantial corporate-jet activity in the area. The Jet Finder sources FAA Part 135 aircraft positioned near KATW and compares hourly rates, repositioning fees, and aircraft availability for each mission.
Customs & International Access
Appleton is a designated general-aviation User Fee Airport for U.S. Customs and Border Protection, supporting international arrivals and departures of 20 passengers or fewer. Service is by prior arrangement (PPR), generally Monday through Friday during posted hours, with after-hours and weekend clearance available for an overtime fee. Operators planning international trips should coordinate CBP arrangements in advance through the FBO and The Jet Finder.
Safety & Planning
The field sits at 918 feet MSL, so density altitude stays well within normal performance limits even on warm summer days. The control tower, ILS to runway 03, and RNAV approaches support reliable IFR access. Winter operations frequently require de-icing, which is available on field; morning departures typically avoid the worst icing and the late-afternoon convective activity common in summer.
Seasonal & Operational Factors
Northeast Wisconsin's climate brings cold, snowy winters with periodic frontal passages that can hold ceilings near IFR minimums, plus Lake Winnebago and Lake Michigan moisture effects. De-icing adds time and cost to winter departures. Regional demand also spikes each summer around EAA AirVenture at nearby Oshkosh (KOSH, about 17 NM south), when KATW serves as a relief and overflow field for business-jet traffic.
Regional Context
KATW anchors private-aviation access to the Fox Cities and the broader Green Bay metro. Alternatives within the region include Green Bay Austin Straubel (KGRB, about 22 NM north) and Oshkosh Wittman Regional (KOSH, about 17 NM south). For most large-cabin charters, Appleton's 8,002-foot runway, customs availability, full-service FBO, and tower make it the strongest year-round jet option in the immediate area.
