1/17/2024 0 Comments Runway lights diagram![]() ![]() High Intensity Approach Light Systems on military aerodromes may be high intensity unidirectional white with cross bars.Light intensity is variable on pilot request. High Intensity Approach Light Systems (LIH ALS) of the Calvert high intensity uni-directional white type are used on precision approach runways at international aerodromes in combination with low intensity red systems.The projectors have two intensities.įour different types of approach light systems are in use in New Zealand: The projectors are aligned to be visible from the approach direction, and are synchronised to flash simultaneously and to show brilliant white flashes at a rate of 60 flashes per minute. Runway end indicator lighting (REIL)Ĭomprises a very high intensity uni-directional light projector located on either side of the runway approximately 30m from the runway extended centre line and downwind of the landing threshold. This lighting will be coded to show white from the threshold to a point 914m from the runway end alternate red and white between 914m and 300m from the runway end and red between 300m and the runway end. Runway centreline lights (RCLL)Ī precision approach runway may also be provided with flush centre line lights over the whole length of the runway. This landing threshold lighting is normally uni-directional green, visible from the approach direction. On non-precision approach runways the displaced threshold lighting may be provided by a wing bar display of lights outboard of the runway edges. When this occurs the runway edge lighting, between the landing threshold and the runway end lights, will be uni-directional red visible from the approach direction and uni-directional white visible from the runway. Where a landing threshold is displaced, the runway end lights may not be coincident with the threshold lighting. This lighting is normally uni-directional red, visible from the direction of the runway. ![]() It may extend across the full width of the runway or have a clear gap about the central section. Is installed across the end of the runway. This lighting is normally uni-directional green, visible from the approach direction. May extend across the full width of the runway or have a clear gap about the central section. Is normally white for the usable portion of the runway. Permanently installed runway lighting consists of runway edge lights, threshold lights, and runway end lights. ![]()
