About Ulsan Airport

Overview

Ulsan Airport serves the southeastern metropolitan region of South Korea, located in the industrial city of Ulsan. Positioned at 45 feet above mean sea level with coordinates 35.593498, 129.352005, the airport supports regional commercial and potential military aviation operations. As a medium-sized airport, it provides critical transportation infrastructure for the Ulsan metropolitan area.

Flying Conditions

The airport's coastal location near the Korean peninsula's southeastern shore suggests potential maritime weather influences and variable wind conditions. With a single runway (18/36) measuring 6,561 feet and constructed of asphalt, pilots should anticipate potential crosswind scenarios typical of coastal environments. Seasonal variations in temperature and precipitation can significantly impact approach and departure conditions.

Notable Features

Ulsan Airport's single runway orientation (18/36) indicates potential alignment with regional topographical or meteorological considerations. The relatively low elevation of 45 feet MSL suggests a relatively flat surrounding terrain, which may reduce certain terrain-related approach complexities. Its geographic position near an industrial region implies potential industrial traffic and associated airspace interactions.

Approach Considerations

Runway 18/36's substantial 6,561-foot length provides adequate operational flexibility for most medium-sized aircraft. Pilots should prepare for potential crosswind components given the coastal location, with careful attention to wind direction relative to the runway's single orientation. Standard instrument approach procedures will be critical for managing varying weather conditions in this maritime environment.
