🔬 Operational & Aerodrome Engineering Comparative Analysis

Comparative aviation metrics evaluated against regional and global physical operational criteria.
ICAO Code 4E / 4F Super-Heavy

Elevation & Atmospheric Density

Lowland / Coastal Basin Aerodrome

Positioned at 944 ft (288 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)

4 Qualifying Aerodromes in Vicinity

Within its 100 NM cluster of 4 neighboring aerodromes, Ontario International Airport is supported by major regional alternatives. Notably, San Bernardino International Airport (SBD) lies just 18.3 NM away with a 10,000 ft runway, offering reliable operational redundancy for commercial diversions and congested airspace rerouting.

Fleet Compatibility & Ground Roll

Primary Runway: 12,197 ft (3,718 m)

With its longest runway exceeding 10,500 ft (3,718 m) and paved surface engineering, Ontario International Airport meets the operational runway criteria for unrestricted long-haul operations by Code 4E and 4F heavy widebody aircraft, including the Airbus A380-800, Boeing 747-8, Airbus A350-1000, and Boeing 777-300ER at high operational weights.
