About Ottumwa Regional Airport

Overview

Ottumwa Regional Airport serves the southeastern Iowa region as a medium-sized airport located at 41.106368, -92.449837. Situated at an elevation of 845 feet MSL, the airport provides critical aviation infrastructure for Wapello County and surrounding areas. Its two runways support a variety of general aviation, training, and potential regional commercial operations.

Flying Conditions

Weather observations indicate predominantly favorable flying conditions, with 69.4% of recorded periods under Visual Flight Rules (VFR). The prevailing northwest winds at an average of 9.1 knots provide stable conditions, though pilots should be prepared for occasional wind gusts up to 33 knots. Temperature ranges from -24°C to 36°C suggest significant seasonal variation, with September, October, and November offering the most consistent VFR weather.

Notable Features

Both runways offer excellent wind alignment, with 100% favorable wind coverage. Runway 04/22 (5,178 feet of asphalt) and Runway 13/31 (5,885 feet of pavement) provide flexible operational options with relatively low average crosswind conditions. The airport's moderate elevation and geographic location in southeastern Iowa contribute to predictable meteorological patterns.

Approach Considerations

Pilots should anticipate generally good visibility averaging 8.9 statute miles, with only 3.6% of observations showing visibility below 3 miles. Fog occurs in approximately 5.1% of observations, primarily affecting low-visibility approaches. The consistent northwest wind suggests Runway 13/31 might offer slightly more favorable approach conditions with its lower average crosswind of 4.6 knots compared to Runway 04/22's 6.9 knots.
