Runway Edge Lights
Runway edge lights are placed along the full length of the runway, in two parallel rows equidistant from the centreline. These are variable-intensity white lights spaced at maximum intervals of 60 metres (200 feet), except at intersections with other runways. On some runways, a 600 metre section of lights or the last third of the runway at the remote end – whichever is shorter – may show yellow towards an aircraft on takeoff. For a certified aerodrome, runway lighting may also include centreline and touchdown zone lighting depending on runway visibility and approach category.
If a runway is used at night, the operator of the aerodrome shall indicate each side of the runway along its length with a line of fixed white lights that is visible in all directions from an aircraft in flight at a distance of not less than two nautical miles.
