Elevation & Atmospheric Density

Lowland / Coastal Basin Aerodrome

Positioned at 191 ft (58 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, Siem Reap-Angkor 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: 11,827 ft (3,605 m)

With its longest runway exceeding 10,500 ft (3,605 m) and paved surface engineering, Siem Reap-Angkor 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.
