11/30/2023 0 Comments Airport runway lights at night![]() Visual glideslope indicators provide the pilot with glidepath information that can be used for day or night approaches. Approach lights can also aid pilots operating under VFR at night. Some systems include sequenced flashing lights, which appear to the pilot as a ball of light traveling toward the runway at high speed. The system configuration depends on whether the runway is a precision or nonprecision instrument runway. In all cases green lights are a routing aid and must only be followed in conjunction with an ATC clearance.Īpproach light systems are primarily intended to provide a means to transition from instrument flight to visual flight for landing. GREEN lights are often used to indicate the route to be followed by an aircraft or vehicle, particularly at night or in periods of reduced visibility. They indicate that a potential hazard exists beyond the lights, but that in conjunction with an appropriate ATC clearance it will be safe to proceed. RED means stop.ĪMBER lights are used to convey a similar but less distinct message. This is the case regardless of whether the lights are fixed, alternating or flashing and is independent of an ATC clearance. RED lights ahead of an aircraft or vehicle mean: it is unsafe to proceed beyond the RED lights. Light Colours and Their Meanings at Runway Entrances RED Some airports also have taxiway centerline lights that are green in color. At many airports, these edge lights may have variable intensity settings that may be adjusted by an air traffic controller when deemed necessary or when requested by the pilot. Omnidirectional taxiway lights outline the edges of the taxiway and are blue in color. This is done by selecting a specified frequency and clicking the radio microphone a specified number of times within a specified time period (for example, 7 "clicks" within 5 seconds on frequency 121.7). This system allows the pilot to control the lighting by using the aircraft radio. ![]() At selected non-towered airports, an ARCAL ( Aircraft Radio Control of Aerodrome Lighting) system is installed. A pilot may request various light systems be turned on or off and also request a specified intensity, if available, from ATC or FSS personnel. At non-towered airports, the lights may be on a timer, or where a Flight Service Station (FSS) is located at an airport, the FSS personnel may control the lighting. Electrical installations for lighting and beaconing of aerodromes - characteristics of inset and eleveated luminaires used on aerodromes and heliports.Īirport lighting is controlled by air traffic controllers (ATCOs) at towered airports. International Electrotechnical Commission, IEC: Advisory Circular, AC 150/5340-30J: Design and Installation Details for Airport Visual Aids, 2018. ![]() ICAO Annex 14-2 Aerodromes volume II, Heliports.ICAO Annex 14-1 Aerodromes Volume I, Aerodrome Design and Operations.International Civil Aviation Organisation (ICAO): The design and usage of civil airport lighting are provisions are addressed by: ![]() Airport lighting is standardized so that airports use the same light colors for runways and taxiways. The variety and type of lighting systems depends on the volume and complexity of operations at a given airport. The majority of airports have some type of lighting to identify and mark taxiways and runways and to control movements of aircraft and vehicles. ![]()
