Quad City International Airport serves the Moline, Illinois metropolitan area as a medium-sized airport situated at 590 feet MSL. Located at coordinates 41.448502, -90.507500, the airport provides critical aviation infrastructure for the Quad Cities region, supporting commercial, general aviation, and potentially military operations.

Flying Conditions

Weather conditions at KMLI demonstrate significant variability, with Visual Flight Rules (VFR) predominating at 68.6% of observed periods. Winds typically blow from the west (270°) at an average of 8.9 knots, with occasional gusts up to 32 knots and calm conditions occurring 15.3% of the time. Seasonal temperature ranges from -24°C to 35°C, with September through November offering the most consistent VFR flying conditions.

Notable Features

The airport features three runways with substantial length: Runway 09/27 at 10,002 feet, Runway 13/31 at 7,001 feet, and Runway 05/23 at 4,509 feet. All runways show 100% favorable wind alignment, with relatively low average crosswind components ranging from 4.2 to 6.2 knots. Visibility averages 9 statute miles, with limited periods of reduced visibility (below 3SM occurring 3.2% of the time).

Approach Considerations

Pilots can expect consistently good wind conditions across all runways, with minimal crosswind challenges. Instrument meteorological conditions occur in 12% of observations (8.5% IFR, 3.4% LIFR), suggesting the importance of having alternate approach strategies. The extensive 10,002-foot Runway 09/27 provides substantial landing and takeoff options for most aircraft types.
