About İstanbul Airport

Overview

İstanbul Airport is a major international aviation hub located in the Arnavutköy district northwest of Istanbul, Turkey. Serving as a critical global connection point, the airport sits at an elevation of 325 feet mean sea level and features five substantial runways capable of handling large commercial aircraft. Its strategic location and extensive runway infrastructure make it a significant regional gateway for international and domestic air traffic.

Flying Conditions

Weather conditions at İstanbul Airport are predominantly favorable for flying, with VFR conditions present 69.8% of the time and MVFR conditions occurring 25.4% of the year. The prevailing winds are from the northeast at an average of 12 knots, with temperatures ranging from -4°C to 27°C and an average of 13.3°C. Pilots can expect optimal visual flying conditions during September, October, and November, with minimal fog occurrence (0.7%) and consistently good visibility averaging 10 statute miles.

Notable Features

The airport boasts five runways with impressive lengths between 10,039 and 13,451 feet, all constructed with asphalt surfaces. All runways demonstrate 100% favorable wind alignment, with moderate crosswind components ranging from 6.4 to 8.2 knots. The airport's multiple parallel runway configuration provides significant operational flexibility for different wind conditions and traffic management.

Approach Considerations

Wind conditions strongly favor approaches along the 16/34 and 17/35 runway axes, with consistent wind patterns from the northeast. Crosswind components remain relatively modest across all runways, typically between 6.4 and 8.2 knots, which should provide comfortable landing conditions for most aircraft. Pilots should anticipate stable approach conditions, particularly during the statistically most favorable months of September through November.
