About Muan International Airport

Overview

Muan International Airport serves the southwestern region of South Korea, located in Piseo-ri, Muan. As a large airport with a single concrete runway measuring 9,186 feet, the facility provides critical aviation infrastructure for the Jeollanam-do province. Its strategic positioning enables both regional and potentially international commercial and cargo operations.

Flying Conditions

The airport's low elevation of 35 feet means minimal altitude-related performance considerations for arriving and departing aircraft. Being situated near the southwestern coastal region, pilots can expect maritime atmospheric influences including potential sea breezes and variable coastal weather patterns. Seasonal wind shifts and occasional maritime weather systems may impact approach and departure conditions.

Notable Features

The single runway (01/19) offers a substantial 9,186-foot length, accommodating most commercial and cargo aircraft types. Its concrete surface provides reliable ground handling characteristics across diverse meteorological conditions. The airport's geographic location suggests potential interactions with coastal terrain and associated microclimate dynamics that pilots should anticipate during flight planning.

Approach Considerations

Runway orientation at 01/19 indicates potential crosswind scenarios depending on prevailing wind directions. Pilots should conduct standard terrain and wind assessments during pre-flight planning, noting the airport's coastal positioning. Standard instrument approach procedures will be critical given the low elevation and potential maritime weather influences.
