Runway 04 at CYOW
Runway 04/22 at Ottawa Macdonald-Cartier International Airport (CYOW) in Ottawa is a 3,300 ft, unlit, asphalt runway oriented 026°/206°. The runway is 75 ft wide, with a 250 ft displaced threshold on the 04 end. SkyMeter has observed 65 landings and 10 departures on this runway over the last 30 days, with approximately 0.0% of arrivals resulting in a go-around. Trace data shows an average final-approach slope of 0.7°, touchdowns averaging 974 ft past the threshold, a typical touchdown ground speed of 89 kt, a 10.7 kt average crosswind component.

Approach Types and Categories
Aircraft approach runways using different procedures based on weather conditions, visibility, and available navigation equipment. An Instrument Landing System (ILS) approach provides precision horizontal and vertical guidance using ground-based radio signals, enabling aircraft to land in low visibility conditions. Visual approaches require pilots to maintain visual contact with the runway and surrounding terrain, typically used during clear weather. Area Navigation (RNAV) approaches use GPS technology to guide aircraft along specific flight paths.
Approach Categories Explained
Category (CAT) classifications define minimum visibility and decision height requirements for instrument approaches. Higher categories enable operations in lower visibility conditions.
Wind and Environmental Factors
Wind conditions directly impact runway operations, influencing approach difficulty, landing performance, and runway selection. Runway 04 benefits from favorable wind alignment, with prevailing winds creating minimal crosswind components for most operations. Average wind speeds of 12 knots pose no operational constraints for commercial aircraft.
24-Hour Wind Pattern
Wind patterns show typical diurnal variation with stronger winds during midday hours.
