Runway centreline and edge lightings are installed on the main taxiway routes at airports. These airport taxiway lights help to guide the aircraft when navigating at the airport.
Airports operating under low visibility conditions usually have green or in some cases cyan taxiway lights on the main taxi routes. Airports operating at night, but not in reduced visibility conditions, may have a green centerline or a flashing blue light, a combination of both, at the discretion of the airport operator.
What is a taxiway approach/demonstration light?
The approach guidance lights guide the aircraft from the runway waiting point to the runway centerline, while pilot guidance lights are installed on the runway before the planned departure from the runway.
It is a light because it alternates between green and yellow and should only be lit when there is permission to enter orbit from this position. The coloration indicates to the pilots that the aircraft is in an area sensitive to ILS.
However, it is important to note that aircraft and cars should not stop in such areas without the express permission of the ATC.
The brake beam lighting system, which is often used at aerodromes operating in low visibility conditions, consists of a series of lights at right angles to the taxiway axis. The lights at Australian airport lighting are the same distance across the width of the runway and when they light up, they show the oncoming plane or car red.
If brake lights are installed at or near a taxiway curve, additional high beam brake lights may be installed to improve their position.
What are center lights?
Intermediate holding positions signals are available at aerodromes where taxiways intersect without a taxiway guidance system and are designed to indicate that aircraft should provide a route to cross-traffic unless they receive a special ATC clearance.
These lights consist of a series of at least three consistent yellow lights that are placed symmetrically across the center of the taxiway and are also called taxiway crossing lights.
What is taxiway edge lighting?
Runway edge lighting is available to explain restrictions on driveways, parking spaces, paved parking areas, service areas and other designated concrete areas where center lighting is not available.
The side lights can also be used to enhance central lighting, maximizing the visual stimuli available to the pilot where difficult corners need to be addressed.
What are taxiway lights for?
Runway lighting is used to indicate the edge or center of the useful runway width to guide pilots safely between the hangars or parking area and the lane.
The airport taxiway lights are used to guide the taxiways and lanes and to indicate the center of the taxiway used. It is normally green, except in the ILS area, where it may also be yellow.
