About San Francisco International Airport
Overview
San Francisco International Airport (KSFO) is a major international airport serving the San Francisco Bay Area, located at coordinates 37.619806, -122.374821. Situated at a low elevation of 13 ft MSL, the airport plays a critical role in supporting commercial, cargo, and general aviation operations for the region. With four substantial runways ranging from 7,500 to 11,870 feet in length, KSFO is well-equipped to handle a diverse range of aircraft.
Flying Conditions
The airport's coastal location near the Pacific Ocean creates complex and dynamic weather conditions that pilots must carefully anticipate. Marine layer fog is a frequent occurrence, particularly during summer months, which can significantly impact visibility and instrument flight conditions. The proximity to the Pacific and surrounding terrain creates microclimatic variations that can produce rapid and localized weather changes.
Notable Features
San Francisco International is situated in a challenging geographical environment, surrounded by water and mountainous terrain that can generate unique aeronautical challenges. The airport's four runways are all constructed of asphalt (ASP) and oriented to accommodate prevailing wind patterns and regional geographic constraints. Pilots should be particularly attentive to potential wind shear and turbulence conditions due to the complex local topography.
Approach Considerations
Runway selection at KSFO is primarily determined by prevailing wind direction, with the 10/28 and 01/19 runway pairs offering flexibility for different wind conditions. The substantial runway lengths (ranging from 7,500 to 11,870 feet) provide significant operational margins for most aircraft types. Pilots should maintain heightened situational awareness due to the potential for rapidly changing coastal weather conditions and complex approach environments.
