About Des Moines International Airport

Overview

Des Moines International Airport serves as a critical transportation hub for central Iowa, located in the state capital. The airport operates with two parallel asphalt runways capable of handling medium-sized aircraft, with substantial runway lengths exceeding 9,000 feet. Its elevation at 958 feet mean sea level provides consistent operational parameters for pilots navigating the midwest region.

Flying Conditions

Weather conditions at Des Moines demonstrate significant variability, with visual flight rules (VFR) predominating at 72.2% of observed periods. Seasonal temperature ranges span from -24°C to 36°C, presenting potential thermal management challenges. Wind patterns are predominantly northwest at an average of 9.5 knots, with occasional gusts up to 43 knots, suggesting potential crosswind considerations during approach and landing.

Notable Features

The airport's dual parallel runways (05/23 and 13/31) offer operational flexibility with nearly identical 9,000-foot lengths. Both runways demonstrate 100% favorable wind alignment, with relatively modest average crosswind components of 7.5 and 4.3 knots respectively. Pilots can expect consistent runway performance characteristics across different wind conditions.

Approach Considerations

Visibility averages 9.1 statute miles, with instrument meteorological conditions occurring in approximately 12.7% of observations. September, October, and January represent the most consistently favorable flying months, characterized by stable weather patterns. Pilots should anticipate potential reduced visibility scenarios, with fog present in 5% of observations and visibility below 3 statute miles occurring in 3.9% of recorded periods.
