Elevation & Atmospheric Density

High-Altitude Aerodrome (Hot & High)

At an elevation of 5,000 ft (1,524 m MSL), this aerodrome operates under severe 'hot and high' atmospheric density penalties. Standard atmospheric air density decreases significantly at this altitude, reducing aerodynamic lift over the wing surfaces and engine thrust output. As a direct operational result, departing commercial airliners require substantially extended ground takeoff rolls and experience reduced initial climb gradients compared to sea-level operations, frequently imposing Maximum Takeoff Weight (MTOW) payload restrictions on ultra-long-haul transcontinental stages.

Regional Density & Alternates (100 NM)

1 Qualifying Aerodrome in Vicinity

Within its 100 NM cluster of 1 neighboring aerodromes, Shirak International Airport is supported by major regional alternatives. Notably, Zvartnots International Airport (EVN) lies just 43.7 NM away with a 12,631 ft runway, offering reliable operational redundancy for commercial diversions and congested airspace rerouting.

Fleet Compatibility & Ground Roll

Primary Runway: 10,564 ft (3,220 m)

With its longest runway exceeding 10,500 ft (3,220 m) and paved surface engineering, Shirak 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.
