Elevation & Atmospheric Density

Lowland / Coastal Basin Aerodrome

Positioned at 844 ft (257 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.
