Located at coordinates 43.984402, -88.556999, the airport provides critical aviation infrastructure for east-central Wisconsin, featuring four runways with varying lengths and surface types.

Flying Conditions

Weather observations indicate predominantly visual flight rule (VFR) conditions, with 65.4% of recorded METARs showing favorable flying weather. Wind patterns are predominantly westerly at an average of 8.1 knots, with occasional gusts up to 26 knots and 13% calm periods. Temperature ranges from -28°C to 31°C, presenting significant seasonal variations that pilots must consider during flight planning.

Notable Features

The airport offers multiple runway options with varying lengths and surfaces: two asphalt runways (13/31 and 5/23) and one concrete runway (18/36). The longest runway, 18/36, measures 8,002 feet, providing substantial operational flexibility. Crosswind conditions are generally moderate, averaging 4.7-5.3 knots across primary runways.

Approach Considerations

Optimal VFR flying conditions are most consistent during autumn months (September, October, November), with high visibility averaging 8.6 statute miles. Both primary runways (13/31 and 18/36) demonstrate 100% favorable wind alignments, facilitating straightforward approaches. Pilots should anticipate potential reduced visibility in 5.2% of observations and prepare for occasional instrument meteorological conditions.
