About Gunsan Airport / Gunsan Air Base

Gunsan Airport / Gunsan Air Base 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

Gunsan Airport, located in southwestern South Korea, serves as a dual-use military and civilian airfield. The airport is situated at a low elevation of 29 ft MSL near the city of Gunsan, providing strategic air access to the region. Its single runway (18/36) spans 9,000 feet and is constructed of concrete.

Flying Conditions

Pilots can expect predominantly favorable VFR conditions, with 71% of observations indicating clear weather and only 3.6% reporting IFR conditions. The airport experiences consistent northerly winds averaging 7.5 knots, with occasional stronger gusts up to 29 knots. Temperature variations are significant, ranging from -8°C to 32°C, with an average of 10.2°C.

Notable Features

The airport's geographic location suggests a relatively flat terrain typical of southwestern Korean coastal regions. With calm wind conditions present 7.2% of the time, pilots should be prepared for potential light and variable wind scenarios. The runway alignment (18/36) demonstrates excellent wind compatibility, with 100% favorable wind conditions and an average crosswind of only 4 knots.

Approach Considerations

November, January, and September represent the most consistent VFR months for operations. Visibility averages 10.3 statute miles, with minimal instances of restricted visibility (below 3SM occurring in only 1.9% of observations). Pilots should note the low probability of fog, which is present in just 1.1% of recorded meteorological conditions.
