De Kooy Airfield / Den Helder Naval Air Station

De Kooy Airfield / Den Helder Naval Air Station is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the NL AIP for current access procedures and restrictions.

Overview

De Kooy Airfield serves as a critical naval aviation facility located in Den Helder, Netherlands, strategically positioned near the North Sea coast. The airport operates as a medium-sized airfield with a single concrete runway (03/21) measuring 4,183 feet in length, supporting both military and potentially some civilian aviation operations.

Flying Conditions

Pilots can expect varied visual flight conditions, with VFR conditions prevailing 43.3% of the time and marginal VFR conditions occurring 34.8% of observations. Wind patterns are predominantly from the south (180°) at an average of 11.6 knots, with temperature ranges from -5°C to 24°C and an average of 9.5°C, creating generally stable flying conditions.

Notable Features

The airfield sits at a low elevation of 3 feet mean sea level, characteristic of the Netherlands' coastal landscape. Its proximity to the North Sea influences local weather patterns, with potential for rapid visibility changes and maritime wind effects. The runway alignment and low elevation suggest minimal terrain challenges for approaching aircraft.

Approach Considerations

Runway 03/21 offers favorable wind conditions 100% of the time, with an average crosswind component of 6.7 knots. Pilots should note the best visual flight conditions typically occur during September, October, and November, with consistently good visibility averaging 10 statute miles and minimal fog occurrences (3.4% of observations).
