About Jeju International Airport

Overview

Jeju International Airport serves as the primary aviation gateway to Jeju Island, located off the southern coast of South Korea. Situated at an elevation of 118 ft MSL, the airport handles significant passenger traffic as the main air transportation hub for this popular tourist destination. Its strategic location and substantial infrastructure support both domestic and international commercial aviation operations.

Flying Conditions

Jeju's maritime island location generates complex and dynamic weather patterns that pilots must carefully anticipate. The airport's dual runway configuration (07/25 at 10,433 ft and 13/31 at 6,268 ft) provides operational flexibility during varying wind conditions. Seasonal wind shifts and potential marine layer developments can significantly impact approach and departure procedures.

Notable Features

The airport is characterized by its substantial runway lengths, with the primary 07/25 runway offering over 10,000 feet of asphalt surface. Its proximity to coastal terrain means pilots should be prepared for potential wind shear and turbulence, particularly during seasonal transition periods. The airport's geographical position at 33.512058, 126.492548 places it in a unique meteorological environment influenced by both maritime and continental air masses.

Approach Considerations

Runway selection will typically depend on prevailing wind directions, with the 07/25 and 13/31 runways providing crosswind options. The extended primary runway (07/25) offers significant landing and takeoff performance advantages for larger aircraft. Pilots should maintain heightened situational awareness regarding potential rapid weather changes typical of island airport environments.
