About Logan International Airport

Overview

Logan International Airport serves as the primary commercial airport for the Boston metropolitan area, located in eastern Massachusetts. Situated at a low elevation of 20 feet MSL, the airport is a critical transportation hub with six runways supporting substantial air traffic. Its strategic coastal location makes it a key gateway for both regional and international flights.

Flying Conditions

The airport's coastal location subjects pilots to variable maritime weather conditions, with potential rapid changes in visibility and wind patterns. Multiple runways (ranging from 2,557 to 10,083 feet) provide operational flexibility across different wind conditions and aircraft types. Proximity to the Atlantic Ocean can introduce marine layer fog and wind shear challenges, particularly during seasonal transitions.

Notable Features

Logan's runway configuration includes six paved runways with lengths accommodating everything from regional jets to wide-body aircraft. The longest runway (15R/33L) extends 10,083 feet, offering substantial landing and takeoff capabilities. The airport's low elevation and complex urban surrounding terrain require precise navigation and awareness of local geographical constraints.

Approach Considerations

Runway selection typically depends on prevailing wind directions, with parallel runway pairs 04L/22R and 04R/22L offering the longest approach surfaces. Pilots should anticipate potential wind variability due to the coastal environment and urban heat island effects. The diverse runway lengths provide multiple options for different aircraft performance characteristics and operational requirements.
