How are Taxiway Centre Lines illuminated?

Taxiway centre lines are illuminated with green lights that run parallel to the taxiway. This design helps pilots easily identify the path they need to follow while taxiing, providing clear visual guidance, particularly during low visibility conditions such as night operations or inclement weather. The use of green lights is standardized in aviation visual navigational aids, as they are universally recognized as indicators for safe navigation along taxiways.

To enhance situational awareness, green lights create a consistent and predictable illumination pattern, thus allowing pilots to maintain awareness of their position relative to the taxiway and any surrounding areas.
