About Mehrabad International Airport

Overview

Mehrabad International Airport serves as a primary aviation hub in Tehran, Iran, situated at an elevation of 3,962 feet above mean sea level. The airport is a large international facility with significant infrastructure, featuring three substantial runways that support diverse aircraft operations. Its strategic location in the capital city makes it a critical transportation center for both commercial and potentially military aviation activities.

Flying Conditions

Located at a considerable elevation of 3,962 ft MSL, Mehrabad experiences varied atmospheric conditions that can impact flight operations. Pilots should anticipate potential performance challenges related to the airport's higher altitude, which can affect aircraft climb rates and engine performance. The multiple runway configurations (09/27, 11L/29R, and 11R/29L) provide operational flexibility to manage different wind and weather scenarios.

Notable Features

The airport features three runways with significant length variations: a shorter 1,554 ft concrete runway (09/27), and two extensive asphalt runways measuring 11,962 ft (11L/29R) and 13,258 ft (11R/29L). These substantial runway lengths accommodate a wide range of aircraft types and provide excellent operational versatility. The geographic coordinates (35.689201, 51.313400) place the airport in the urban environment of Tehran, which introduces potential complex airspace and terrain considerations.

Approach Considerations

Runway orientation suggests potential wind-related approach considerations, with multiple runway headings offering options for different wind conditions. The longest runway (11R/29L at 13,258 ft) provides extensive landing and takeoff capabilities for heavy aircraft. Pilots should prepare for potential urban terrain effects and be ready to adapt to the airport's elevation when planning approaches and departures.
