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.
