About Mariscal Sucre International Airport

Overview

Mariscal Sucre International Airport serves as the primary international airport for Quito, Ecuador, located at an impressive elevation of 7,841 feet mean sea level. As a large airport situated in the capital city, it handles significant commercial and passenger traffic for the region.

Flying Conditions

The high-altitude location of 7,841 feet MSL presents unique atmospheric challenges for pilots, including reduced air density and potential performance limitations for aircraft. Pilots should anticipate thinner air conditions that will affect aircraft performance, climb rates, and engine efficiency during operations.

Notable Features

The airport features a single runway (18/36) with a substantial length of 13,445 feet, constructed with concrete (CON) surface. Its geographic coordinates at -0.125399, -78.354306 place the airport in the mountainous terrain of the Ecuadorian Andes, which introduces complex topographical considerations for approach and departure procedures.

Approach Considerations

Given the single runway's orientation of 18/36, wind conditions and terrain will significantly influence approach strategies. Pilots must be prepared for potential wind shear, altitude-related performance constraints, and the need for precise navigation in the mountainous environment surrounding Quito.
