Located at coordinates 37.668173, -95.486727, the airport provides critical aviation infrastructure for southeastern Kansas, supporting local and regional transportation needs.
Flying Conditions
Weather conditions at KCNU demonstrate predominantly favorable VFR flying conditions, with 75.5% of observations reporting visual flight rules. Temperatures range dramatically from -16°C to 32°C, with an average of 10.6°C, requiring pilots to be prepared for significant temperature variations. Wind patterns are consistently from the south at an average of 8 knots, with occasional peaks up to 31 knots.
Notable Features
The airport features two runways: a 2200-foot grass runway (08/26) and a 4255-foot asphalt runway (18/36). Both runways demonstrate 100% favorable wind alignment, with relatively modest average crosswind conditions of 6.3 knots for the grass runway and 3.7 knots for the asphalt runway. Visibility averages 9.1 statute miles, with only 2.4% of observations showing visibility below 3 miles.
Approach Considerations
Pilots should note January, September, and October offer the most consistent VFR conditions for operations. With low occurrence of IFR (6.1%) and LIFR (6.6%) conditions, the airport generally provides reliable access. The southerly prevailing winds and low average crosswinds make both runways consistently accessible, with minimal wind-related approach challenges.
