Elevation & Atmospheric Density

Lowland / Coastal Basin Aerodrome

Positioned at 118 ft (36 m MSL), this aerodrome operates near standard International Standard Atmosphere (ISA) sea-level air density. High ambient air pressure provides optimal turbine thrust conversion, maximum wing lift coefficients, and minimal ground roll distance requirements, allowing long-haul flights to depart at maximum structural takeoff weight limits without atmospheric density penalties.

🧭

Regional Density & Alternates (100 NM)

0 Qualifying Aerodromes in Vicinity

With no qualifying commercial facilities with paved runways ≥5,000 ft within a 100 NM radius, Jeju International Airport functions as an isolated regional aviation hub. Scheduled air services and transiting aircraft must calculate extended diversion reserves to alternate airfields outside the immediate 100 NM quadrant.

Fleet Compatibility & Ground Roll

Primary Runway: 10,433 ft (3,180 m)

At 10,433 ft (3,180 m), the primary runway comfortably accommodates mid-to-large twin-aisle widebody transports (such as the Boeing 787-9 and Airbus A330-900) as well as maximum-range narrowbody transcontinental configurations (Airbus A321XLR and Boeing 737 MAX 9) under typical atmospheric conditions.
