About Decatur Airport
Overview
Decatur Airport serves central Illinois as a medium-sized airport located near the city of Decatur. Situated at 682 feet above mean sea level with coordinates 39.834599, -88.865700, the airport provides critical aviation infrastructure for the region. Its three runways offer diverse operational capabilities for various aircraft types.
Flying Conditions
Weather conditions at Decatur Airport demonstrate significant variability, with visual flight rules (VFR) predominating at 68.6% of observations. Pilots can expect prevailing westerly winds averaging 9.4 knots, with temperature ranges from -24°C to 37°C. September, October, and January offer the most consistently favorable VFR conditions, while visibility typically remains excellent at an average of 9 statute miles.
Notable Features
The airport features three runways with different surface compositions: two PEM (Pavement with Exceptional Maintenance) and one ASP (Asphalt) runway. Runway lengths vary from 5,299 feet to 8,496 feet, providing flexibility for different aircraft categories. Wind data indicates consistent runway usability, with all three runways showing 100% favorable wind alignment and modest average crosswind conditions between 5.6 and 6.3 knots.
Approach Considerations
Pilots should anticipate predominantly westerly winds when planning arrivals and departures. The longest runway (06/24 at 8,496 feet) offers the most substantial landing and takeoff options. Marginal conditions occur in approximately 31.4% of observations, with instrument (IFR/LIFR) conditions present 13.5% of the time, suggesting potential need for alternate planning during certain periods.
