TAXIWAY CENTRE LINE AND EDGE LIGHTING
Airports that operate in low visibility conditions usually have green or in some cases cyan, taxiway centreline lights on main taxiway routes. Where taxiway centreline lighting is provided, blue taxiway edge lighting can also be provided as complementary guidance on sections of taxiway that are assessed as potentially difficult to negotiate for instance, curves.
Airports that operate at night time but not in low visibility may have either green centerline or blue edge lighting or a combination of the two at the discretion of the airport operator.
TAXIWAY LEAD-ON / LEAD-OFF LIGHTING
Green taxiway centreline lighting may also be installed on a runway prior to a designated taxiway exit to provided lead-off guidance. Lead-on guidance from runway holding points onto the runway centerline may also be provided. If installed it should only be illuminated only if clearance to enter that runway from that position is permitted. The lights used on the lead-on and lead-off circuits are alternately coloured green and yellow which indicates to the pilot that the aircraft is in the ILS sensitive area, if it is installed. It should be noted that aircraft and vehicles should not stop in such areas without obtaining explicit ATC approval.
TAXIWAY STOP BAR LIGHTING
Stop bar lighting is usually provided at airports that operate in LVP conditions. They consist of a row of lights, at right angles to the taxiway centreline, and are spaced evenly across the width of the taxiway showing red, when lit, towards an approaching aircraft or vehicle. When the lights are positioned prior to all taxiway/runway intersections. Where a Stop Bar is located on or close to a bend in a taxiway, additional elevated stopbar lights may be installed so as to improve awareness of the Stop Bar location.
TAXIWAY INTERSECTION LIGHTS
These are sometimes used at airports where there are several intersecting taxiways but with no Taxiway Guidance System. They consist of a row of at least 3 steady yellow lights installed symmetrically across the taxiway centreline. This indicates that aircraft or vehicles should give way to crossing traffic unless a otherwise instructed to do so by ATC.
