Overview & Role
Chicago Executive Airport (KPWK/PWK) is a public-use, towered reliever in Wheeling and Prospect Heights, Illinois — roughly 18 miles north of downtown Chicago and only about 10 miles from O'Hare. With approximately 167,000 annual operations it ranks among Illinois's busiest airports and is the metro area's leading dedicated business-aviation gateway, letting travelers bypass the congestion and ground delays of O'Hare and Midway.
Runway Capability
The airport has three asphalt runways: 16/34 at 5,001 ft (the primary, ILS-equipped), 12/30 at 4,415 ft, and 06/24 at 3,680 ft. The 5,001 ft main runway supports the full range of light, midsize, and super-midsize jets, with heavy-jet access possible after a weight-and-temperature performance review. Multiple runway alignments provide strong crosswind options year-round.
FBOs & Ground Services
Three national FBO brands operate on the field: Signature Flight Support, Atlantic Aviation, and Hawthorne Global Aviation Services. All offer Jet-A and 100LL, line service, hangar and ramp parking, crew cars, and passenger lounges, with Signature and Atlantic staffing 24/7. The competitive FBO environment generally keeps fuel and handling pricing favorable for transient business jets.
U.S. Customs & International Arrivals
Contrary to some older listings, Chicago Executive does have on-field U.S. Customs and Border Protection service. CBP is staffed Monday–Friday 11:00 a.m.–7:00 p.m. local with no off-hour surcharge during those hours. Weekday clearances must be arranged by 5:00 p.m. the prior business day (Friday by 5:00 p.m. for weekend arrivals). This makes PWK a viable international port of entry for the north Chicago suburbs.
Noise Abatement & Operational Factors
KPWK enforces a voluntary noise-abatement program: no turbine engine run-ups are permitted between 10:00 p.m. and 7:00 a.m. local, and runway 12/30 is the preferred runway during the 2200–0600 overnight window. Crews should review the airport's published noise procedures and obtain ATIS/clearance accordingly. There is no hard weight limit or PPR/slot requirement for standard business-jet operations.
Seasonal & Weather Considerations
At 647 ft MSL, density altitude is rarely limiting — even on hot summer afternoons it stays well within normal performance bands. Chicago winters bring frontal passages with periodic IFR ceilings and freezing precipitation, so instrument currency and de-ice planning are recommended November through March. Summer convection peaks in late afternoon; early-morning departures typically see the smoothest conditions.
Regional Context
PWK is the closest full-service business-aviation field to Chicago's affluent North Shore and northwest suburbs. Alternatives include DuPage (KDPA, ~20 NM west), Waukegan (KUGN, ~19 NM north), and Schaumburg (06C, ~10 NM). For travelers headed downtown or to the North Shore, Chicago Executive's proximity and three competing FBOs usually make it the most efficient choice over O'Hare or Midway.
