Airport Runway and Approach Lighting

Rapid and extensive changes in airport lighting have been made within the last ten years. The necessity for providing elevated high intensity runway and approach lights as an aid during low visibility conditions, both day and night, has been generally recognized. With the advent of adequate runway lighting, boundary lights and floodlights (for runways) have become unnecessary. The provision of high intensity runway and approach lights of the latest type results in a 10,000 per cent increase in power consumption per runway.
