![]() Centerline lights are placed at the center of a taxiway and are green, unless they are where a taxiway crosses a runway, then they’ll alternate between yellow and green. Taxiways also consist of several other types of lights, besides traditional blue edge lights, like centerline lights, as briefly mentioned earlier, clearance bar lights, runway guard lights, and stop bar lights. Other runway lights include threshold lights, which are green, end lights, which are red, and REILs, or runway end identifier lights, which are bright strobe lights. The reason for this is to let pilots know that they’re almost at the end of the runway. The lights placed at the last 2000 feet of a runway are yellow. An airport’s choice of runway light configuration depends on their locality’s weather conditions, but the edge lights are almost always white. On the other hand, runway lights range from white, yellow, to red and green. These lights are either elevated, like Hali-Brite’s taxiway lights, or set into the ground. Blue taxiway edge lights are typically the first lights an airplane passenger sees. In the dark, humans best see the color blue green, which is why taxiway edge lights are blue and centerline lighting is green. These lights guide the flight crew and vehicle drivers in low visibility conditions, which includes nighttime operations. ![]() Since runways and taxiways have different purposes, they utilize different colored lights.Īirport taxiway lights are always blue. A runway is the paved airstrip used for an aircraft to take off and land whereas a taxiway is a path that connects to a runway. When it comes to the question of what color airport taxiway lights are, the viewer needs to take one important aspect into account: taxiways aren’t the same as runways. ![]() This international consistency enhances the safety of our commercial airline industry, which transports nearly 1.5 billion people annually around the world.Airports consists of a variety of lights, all flashing and illuminating in different colors. Heathrow, JFK, Hong Kong-the color, placement, and configuration of runway lights are universal at all airports. These lights are typically used in conjunction with approach light systems, which extend beyond the runway ends, providing a visual queue for the pilots to line-up the aircraft during approach. Recessed in-pavement runway lights, also white in color, are common at most large airports to provide enhanced runway visibility.The departure end is marked by red lights delineating the end of operational pavement.The ends, or thresholds, of the runways have green lights at the “beginning” of the runway, or approach end.Runway edge lights are white, transitioning to amber near the departure end of the runway.Taxiway edge lights are always blue and, in some cases, are accompanied by green recessed, in-pavement centerline lights for enhanced visibility during inclement weather.In reality, all lights on an airfield are essential to the safe and efficient aircraft operations during takeoff, landing, and taxiing. ![]() “Hopefully the two people piloting the plane,” I joked. “Who knows what all those lights are for?” he asked. The gentleman next to me appeared mesmerized by the collage of lights on the airfield. During an evening return flight from New York City to Portland, Maine, I gazed out the side window of the aircraft as we taxied to the end of one of JFK’s runways for takeoff. ![]()
