rapidExitTaxiwayIndicator | 1 Rapid exit taxiway indicator lights (RETILs) provide pilots with distance-to-go information to the nearest rapid exit taxiway on the runway, to enhance situational awareness in low visibility conditions and enable pilots to apply braking action for more efficient roll-out and runway exit speeds. Rapid exit taxiway indicator lights shall be fixed unidirectional yellow lights, aligned so as to be visible to the pilot of a landing aircraft in the direction of approach to the runway.
stopwayEdge | 2 Stopway edge lights are used to outline the edges of the stopway during periods of darkness or restricted visibility conditions. Stopway lights shall be placed along the full length of the stopway and shall be in two parallel rows that are equidistant from the centre line and coincident with the rows of the runway edge lights. Stopway lights shall also be provided across the end of a stopway on a line at right angles to the stopway axis as near to the end of the stopway as possible and, in any case, not more than 3 metres outside the end.
apronFlood | 3 Apron floodlights provide adequate illumination on all apron service areas.
taxiwayCenterline | 4 Taxiway centerline lights define the centerline of the taxiway and are used to facilitate ground traffic under low visibility conditions. They are located along the taxiway centerline in a straight line on straight portions, on the centerline of curved portions, and along designated taxiing paths in portions of runways, ramp, and apron areas. Taxiway centerline lights are steady burning and emit green light.
taxiwayEdge | 5 Taxiway edge lights are used to outline the edges of taxiways during periods of darkness or restricted visibility conditions. These fixtures emit blue light.
runwayTurnPad | 6 Runway turn pad lights provide continuous guidance on a runway turn pad intended for use in runway visual range conditions less than a value of 350 m, to enable an aeroplane to complete a 180-degree turn and align with the runway centre line. Runway turn pad lights shall be unidirectional fixed lights showing green with beam dimensions such that the light is visible only from aircraft on or approaching the runway turn pad.
stopbars | 7 Stop bar lights are used to confirm the ATC clearance to enter or cross the active runway in low visibility conditions. A stop bar consists of a row of red, unidirectional, steady-burning in-pavement lights installed across the entire taxiway at the runway holding position, and elevated steady-burning red lights on each side.
intermediateHolding | 8 A light designating a position intended for traffic control at which taxiing aircraft and vehicles shall stop and hold until further cleared to proceed, when so instructed by the aerodrome control tower. Intermediate holding position lights shall consist of three fixed unidirectional lights showing yellow in the direction of approach to the intermediate holding position with a light distribution similar to taxiway centre line lights if provided. The lights shall be disposed symmetrically about and at right angle to the taxiway centre line, with individual lights spaced 1.5 metres apart.
deicingAreaExit | 9 De-icing/anti-icing area exit lights should be provided at the exit boundary of a remote de-icing/anti-icing area adjoining a taxiway. De-icing/anti-icing facility exit lights shall consist of in-pavement fixed unidirectional lights spaced at intervals of 6 metres showing yellow in the direction of the approach to the exit boundary with a light distribution similar to taxiway centre line lights.
runwayGuard | 10 Runway guard lights provide warning to pilots and drivers of vehicles when they are operating on taxiways, that they are about to enter an active runway. There are two standard configurations of runway guard lights. Configuration A is a pair of unidirectional flashing yellow lights located at each side of the taxiway at a distance from the runway centre line. Configuration B are unidirectional flashing yellow lights spaced at intervals of 3 metres located across the taxiway at a distance from the runway centre line.
visualDockingGuidance | 11 A visual docking guidance system indicates, by a visual aid, the precise positioning of an aircraft on an aircraft stand when other alternative means, such as marshallers, are not practicable.
aircraftStandManeuver | 12 Aircraft stand manoeuvring guidance lights facilitate the positioning of an aircraft on an aircraft stand, on a paved apron, or on a de-icing/anti-icing facility intended for use in poor visibility conditions.
roadHoldingPosition | 13 A road holding position light designates a position at which vehicles may be required to hold. The road-holding position light shall comprise of either a controllable red (stop)/green (go) traffic light or a flashing-red light.
runwayCenterline | 14 Runway centerline lights define the centerline of a runway, and are installed on some precision approach runways to facilitate landing and Take-off under adverse visibility conditions. Runway centre line lights shall be fixed lights showing variable white from the threshold to the point 900 metres from the runway end; alternate red and variable white from 900 metres to 300 metres from the runway end$$$$$ and red from 300 metres to the runway end, except that for runways less than 1 800 metres in length, the alternate red and variable white lights shall extend from the mid-point of the runway usable for landing to 300 metres from the runway end.
runwayEdge | 15 Runway edge lights are used to outline the edges of runways during periods of darkness or restricted visibility conditions. These light systems are classified according to the intensity or brightness they are capable of producing: they are the High Intensity Runway Lights (HIRL), Medium Intensity Runway Lights (MIRL), and the Low Intensity Runway Lights (LIRL). The HIRL and MIRL systems have variable intensity controls, whereas the LIRLs normally have one intensity setting.
runwayEndIdentifierLight | 16 REILs are installed at many airfields to provide rapid and positive identification of the approach end of a particular runway. The system consists of a pair of synchronized flashing lights located laterally on each side of the runway threshold. REILs may be either omnidirectional or unidirectional facing the approach area. They are effective for Identification of a runway surrounded by a preponderance of other lighting; Identification of a runway which lacks contrast with surrounding terrain$$$$$ Identification of a runway during reduced visibility. REILs are flashing white lights with a flash frequency between 60 and 120 per minute.
touchdownZone | 17 Touchdown Zone lights define the touchdown zone of a runway, and are installed on some precision approach runways to facilitate landing and Take-off under adverse visibility conditions. Touchdown zone lights shall extend from the threshold for a longitudinal distance of 900 metres, except that on runways less than 1800 metres in length, the system shall be shortened so that it does not extend beyond the midpoint of the runway. The pattern shall be formed by pairs of barrettes symmetrically located about the runway centre line. The lateral spacing between the innermost lights of a pair of barrettes shall be equal to the lateral spacing selected for the touchdown zone marking. The longitudinal spacing between pairs of barrettes shall be either 30 metres or 60 metres.
threshold | 18 A group of lights identifying the beginning of the landing surface of the runway. Runway threshold lights are variable intensity red and green units in the form of wing bars along each side of the runway centerline, except that for Category II and higher runways, the red and green lights extend along the full width of the runway. Green shows in the approach direction and red shows in the opposite. When a threshold is at the extremity of a runway, the threshold lights shall be placed in a row at right angles to the runway axis as near to the extremity of the runway as possible and, in any case, not more than 3 metres outside the extremity. When a threshold is displaced from the extremity of a runway, threshold lights shall be placed in a row at right angles to the runway axis at the displaced threshold.
runwayEnd | 19 Runway end lights are used to outline the landing end of the runway during periods of darkness or restricted visibility conditions. Runway end lights shall be fixed unidirectional lights showing red in the direction of the runway. The intensity and beam spread of the lights shall be adequate for the conditions of visibility and ambient light in which use of the runway is intended.
landandHoldShort | 20 Land and hold short lights are used to indicate the hold short point on certain runways which are approved for Land and Hold Short Operations (LAHSO). Land and hold short lights consist of a row of pulsing white lights installed across the runway at the hold short point. Where installed, the lights will be on anytime LAHSO is in effect. These lights will be off when LAHSO is not in effect.
taxiwayExitCenterLights | 21 Taxiway exit centerline lights identify a track on a runway where an aircraft may make a smooth transition from the runway environment to an adjacent taxiway. The lights are spaced at longitudinal intervals of not more than 15 metres, except that, where runway centre line lights are not provided, a greater interval not exceeding 30 metres may be used. The lights alternate green and white.
touchdownAndLiftOffArea | 22 Lights placed to identify the designated Touchdown and Lift-Off area. Touchdown and lift-off area perimeter lights shall be placed along the edge of the area designated for use as the touchdown and lift-off area or within a distance of 1.5 metres from the edge. Where the touchdown and lift-off area is a circle the lights shall be: a) located on straight lines in a pattern which will provide information to pilots on drift displacement; and b) where a) is not practicable, evenly spaced around the perimeter of the touchdown and lift-off area at the appropriate interval except that over a sector of 45 degrees the lights shall be spaced at half spacing.
finalApproachTakeOffArea | 23 Lights placed along the edge identifying the final approach and take-off area. Final approach and take-off area lights shall be fixed omnidirectional lights showing white. Where the intensity of the lights is to be varied the lights shall show variable white.

Description: | A macrolanguage is a set of closely related language varieties (dialects) that generally have a common linguistic identity and a common written form; this may occur when there is a transitional socio-linguistic situation in which sub-communities of a single language community are diverging. The language of the geographic name source should be distinguished from the language of origin or etymology of a geographic name; for example, considering the place name 'San Jose, California' the language of the source of this geographic name may be English if it is determined from a United States map, regardless of the fact that this geographic name means 'St. Joseph, California' in Spanish.
