What are the colors and spacing of taxiway centre lights?

• A. Red; spacing 20 m
• B. Yellow; spacing 50 m
• C. Green; spacing no more than 60 m
• D. Blue; spacing 40 m

Answer: (C)

Taxiway centreline lighting provides a continuous visual path along the taxiway. The lights are green, which distinguishes the taxiway centerline from runway lighting and other markings. The spacing is set so that you don’t lose the line in typical taxiing speeds and visibility; a standard guideline is that the distance between successive centerline lights should not exceed 60 meters. This makes it easy to follow the path, even in reduced visibility. Red lights are used for runway or boundary indications, blue lights mark taxiway edges, and yellow is not the standard color for taxiway centreline lights, so that option doesn’t fit.
