Davison Army Air Field (KDAA) is a medium-sized airport located at Fort Belvoir, serving military aviation operations in the Washington, D.C. metropolitan area. Situated at 73 feet above mean sea level with coordinates 38.715000, -77.181000, the airport provides critical infrastructure for military aviation activities in the region.

Flying Conditions

The airport experiences predominantly VFR conditions, with 73.3% of observations reporting visual flight rules. Temperature ranges from -11°C to 32°C, creating diverse flying environments throughout the year. Wind patterns are characterized by a northwest prevailing direction at an average of 6.6 knots, with calm conditions occurring 49.7% of the time.

Notable Features

The primary runway 14/32 is 5,618 feet long with an asphalt surface, offering flexible operational capabilities. The airport's location near Washington, D.C. implies potential airspace complexity and proximity to controlled airspace. Visibility averages 9.4 statute miles, with minimal instances of restricted visibility (below 3SM occurring only 1.3% of the time).

Approach Considerations

Runway 14/32 demonstrates 100% favorable wind conditions with an average crosswind of only 2.7 knots. October, November, and January represent the most consistently favorable VFR months for operations. Pilots should anticipate northwest wind patterns and prepare for potential variability in local weather conditions.
