About Dupage Airport

Overview

DuPage Airport serves the Chicago/West Chicago metropolitan area as a medium-sized airport located west of Chicago. Situated at an elevation of 759 feet MSL, the airport provides crucial general aviation infrastructure for the region, supporting diverse aircraft operations across its four runways.

Flying Conditions

Historical weather data indicates predominantly favorable flying conditions, with 65.1% of observations reporting VFR conditions. Pilots can expect moderate wind conditions, with a prevailing westerly wind at an average of 9.1 knots and occasional gusts up to 30 knots. September through November represent the most consistently favorable VFR months, offering optimal flying weather.

Notable Features

The airport features four runways with varying lengths and surface types, providing flexibility for different aircraft types and operational needs. The two concrete runways (02L/20R and 02R/20L) offer longer surfaces suitable for larger aircraft, while the two asphalt runways (10/28 and 15/33) provide additional operational capacity. Temperature variations range significantly from -24°C to 32°C, indicating potential seasonal operational considerations.

Approach Considerations

All runways demonstrate 100% favorable wind alignment, with relatively consistent crosswind averages between 5.4 and 6 knots. The longer concrete runways (02L/20R at 7570ft and 02R/20L at 5100ft) provide the most substantial landing options. Visibility averages 8.8 statute miles, with only 4.2% of observations reporting visibility below 3 miles and minimal fog occurrence at 1.9%.
