About Ottawa Macdonald-Cartier International Airport

Overview

Ottawa Macdonald-Cartier International Airport serves as the primary airport for Canada's capital city, located in eastern Ontario. Situated at an elevation of 374 feet above mean sea level, the airport provides critical transportation infrastructure for government, commercial, and regional aviation operations in the National Capital Region.

Flying Conditions

The airport's three runways offer comprehensive wind coverage, with lengths ranging from 3,300 to 10,000 feet. The multiple runway configurations (04/22, 07/25, and 14/32) all feature asphalt surfaces, providing pilots with flexible operational capabilities across different wind conditions and aircraft types.

Notable Features

Located at coordinates 45.322498, -75.669197, the airport is positioned in a relatively flat urban terrain typical of the Ottawa region. The substantial 10,000-foot runway (14/32) provides excellent operational capacity for larger commercial and cargo aircraft, while the shorter runways offer additional flexibility for smaller aircraft.

Approach Considerations

Pilots should note the significant variation in runway lengths, with the longest runway (14/32) offering 10,000 feet of asphalt surface. The multiple runway orientations provide options for handling various wind directions, with the 07/25 and 14/32 runways offering particularly robust length for most commercial and business aviation requirements.
