Airfield Lighting

Airfield lighting systems extend an airport’s usefulness into periods of darkness and/or poor visibility. A variety of lighting systems a re installed at the airport for this purpose. These lighting systems, categorized by function, are summarized as follows. Identification Lighting: The location of an airport at night is universally indicated by a rotating beacon. A rotating beacon project s two beams of light, one white and one green, 180 degrees apart. The existing rotating beacon a t Chino Air port is located south of runway 8L-26R, atop the Air Traffic Control Tower. Pavement Edge Lighting: Pavement edge lighting utilizes light fixtures placed near the edge of the pavement to define the lateral limits of the pavement. This lighting is essential for safe operations during night and/or times of low visibility in order to maintain safe and efficient access to and from the runway and aircraft parking areas. Runway 3-21 and Runway 8R-26L are equipped with medium intensity runway lights (MIRL). Runway 8L-26R is equipped with high intensity runway lights (HIRL). All taxiways, with the exception of Taxiways G and J, are equipped with medium intensity taxiway lighting (MITL). Visual Approach Lighting: To provide pilots with visual descent information during landings to the runway, visual glide slope indicators are commonly provided at airports. A precision approach slope indicator (PAPI) is installed a t the Runway 8R, 26L, 3, 21 and 26R ends. A PAPI system consists of a configuration of lights near the runway threshold which enable pilot s to determine whether they are above or below the designed descent path to the runway end. Airfield Signs: Airfield identification signs assist pilots in identifying their location on the airfield, hold positions, and direct pilots to their desired location. Lighted signs are installed at all taxiway and runway intersections.
