About St. John's International Airport

Overview

St. John's International Airport serves as a critical aviation hub in Newfoundland, Canada, located at coordinates 47.618599, -52.751900. Situated at an elevation of 461 feet mean sea level, this large airport provides essential transportation infrastructure for the eastern Canadian region. The airport supports multiple runway configurations that can accommodate a wide range of aircraft operations.

Flying Conditions

The airport's three asphalt runways offer versatile operational capabilities, with lengths ranging from 5,028 to 8,502 feet. Located in an eastern coastal environment, St. John's experiences variable weather conditions typical of the Newfoundland maritime climate. Pilots should anticipate potential rapid weather changes and prepare for potential wind shifts across the airport's multiple runway orientations.

Notable Features

St. John's International Airport features three parallel and intersecting runways (02/20, 10/28, and 16/34), providing multiple approach and departure options. The airport's elevation of 461 feet and coastal location suggest potential terrain and wind considerations for arriving and departing aircraft. Runway surface types are consistently asphalt, supporting reliable ground operations across all runways.

Approach Considerations

With runway headings of 02/20, 10/28, and 16/34, pilots have multiple options for approach and departure based on prevailing wind conditions. The longest runway (10/28 at 8,502 feet) provides the most extensive landing and takeoff capabilities. Pilots should carefully assess current wind direction and runway length when planning approach and departure strategies.
