Elevation & Atmospheric Density

Lowland / Coastal Basin Aerodrome

Positioned at 24 ft (7 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.

Fleet Compatibility & Ground Roll

Primary Runway: 10,499 ft (3,200 m)

At 10,499 ft (3,200 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.
