About Seoul Air Base (K-16)

Seoul Air Base (K-16) is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the KR AIP for current access procedures and restrictions.

Overview

Seoul Air Base (K-16) serves as a strategic military and potential civilian aviation facility located in Seongnam, South Korea. Situated at 92 feet above mean sea level, the base features two substantial concrete runways capable of handling significant aircraft operations. Its proximity to Seoul makes it a critical aviation infrastructure point for the region.

Flying Conditions

The airport demonstrates consistently favorable flying conditions, with VFR conditions predominating at 75.6% of observations. Temperature ranges from -13°C to 31°C, providing a relatively stable operational environment throughout the year. Wind patterns are predominantly southerly at an average of 3.7 knots, with November, January, and September presenting the most optimal VFR conditions.

Notable Features

Both runways (01/19 and 02/20) offer extensive lengths of 9000 and 9700 feet respectively, accommodating a wide range of aircraft types. The airport's geographical position and runway orientation suggest excellent wind alignment, with 100% favorable wind conditions for both primary runways. Crosswind averages remain minimal at approximately 2.1-2.2 knots.

Approach Considerations

Pilots can expect highly predictable approach conditions with consistent wind patterns and excellent visibility averaging 10 statute miles. The airport rarely experiences low visibility challenges, with fog occurring in only 0.7% of observations and instances of visibility below 3 statute miles being statistically negligible. Both runways provide reliable approach and landing opportunities across diverse meteorological conditions.
