![]() ![]() The runway edge lighting system ensures that the airplane is on the right course on the runway generally, the runway edge lights are a series of lights located on the left and right side of the runway, illuminating the safe path of the runway for a safe landing. The pilots need to have a visual guide on the actual width of the runway, so they don’t end up going off the rails. These endpoint identifier lights flash green lights indicating the approach of the end of the runway to identify pilots where to land or validate that they are not running short of the runway. On the opposite end, the lights appear red, which informs the pilots that they are approaching the departure end of the runway and the whole runway they left behind them the pilots should either take off or pull back before reaching the runway end lighting if there are any sort of issues with the aircraft.Īlso, the runway end identifier light(REIL) is placed on either side of the runway at the endpoint. With the full length of the runway stretching in front of them. This lighting system lets the pilots know about the endpoint of the runway. These are the white flashlight, unidirectional which identifies the beginning of a runway unlike the other lighting system of the approach light, the runway end lighting is installed in just a pair, one at each side of the runway. The lighting system that marks the end of the runway extends all the way across the width of the runway at either of the ends. The ending runway point at the airport is marked with runway end lighting or runway threshold identification lights(RTIL). The touchdown lighting zone starts 100 feet before the runway threshold and continues throughout the 3,000 feet or mid-point of the runway. On the other hand, the touchdown zone is the lighting system that consists of groups of three white lights placed to the right and three white lights placed to the right of the runway centerline lights. Although it is not exactly a touchdown point, the threshold approaching lights mark the start of the safe landing part on the runway. The lighting system that shows the direction of the runway has a different approach lighting system the simplest form has a cross design and usually consists of 17 approach lights that can be visible to the pilot crew even from farther distances.įurther, part of the approach lighting system, the threshold approach lights that flash green color are the unidirectional type of lighting system in the runway that identifies the beginning part of the touchdown point for the aircraft. In contrast, the non-precision instruments runway has approach lighting spaces that cover an area of 1,400 feet to 1,500 feet. The size of the approach light on the runway extends from 2,400 feet to 3000 feet into the approach area for precision on instrument runways. The purpose of the approach to light the runway is to indicate the actual direction of the runway and allow the pilots to visualize the touchdown zone from farther distances. Unlike other runway lightings, the approach lighting system is positioned at the approach area on the runway and stops at the threshold. ![]() The approach lights at the runway are the first lights that the pilot will reach during the landing process. There are generally nine types of lighting systems practiced in the aviation industry, from the touchdown lighting that indicates the touch zone for the incoming aircraft to the PAPI lighting system that helps the pilot to keep track with the correct course. Basically, the runway centerline lights are placed between the distances of 50 feet apart from each other and are required for all CAT II and CAT III runways and even for some of the CAT I runways depending on the operating hours and size of the aircraft. And, the centerline lighting at the final 1,000 feet of runway is indicated by all red centerline lighting systems. The centerline lighting system on the runway is generally in white color near the approaching end of the runway and transits to alternating white and red lights in its length at 3,000 feet from the end of the runway, the centerline lights in the runway remain white. The runway’s centerline lights indicate the middle position of the runways, whereas the edge lighting, which compromises white lights on both edges of the runway, indicates the runway edges so the pilot can navigate properly without any mishap. It is a component of the airport lighting system, guide the airplanes through runways and taxiways at night or adverse weather conditions where the navigation becomes necessary without clear visuals on the runway.
