Avlite Systems has introduced an innovative LED inset
which is a LED omnidirectional inset lighting fixture
light that addresses FATO (final-approach take-off), TLOF
(touch-down lift-off), flight path alignment and aiming point
The inset light fully meets the ICAO (International Civil
Aviation Organisation) Annex 14 - Volume II. Heliports 2013
specifications and the FAA (Federal Aviation Authority)
Engineering Brief 87.
The physical projection of the inset light above ground level
does not exceed 10 mm, which, together with a smooth low
profile outer surface, prevents any damage to the helicopter or
any other vehicle tires. The advanced LED optics ensures
optimum light output even in the worst weather conditions. The
inset light can be mounted in either 5-inch shallow base can or
8-inch shallow base-can using an adapter ring.
Avlite's LED Omnidirectional Inset heliport light is
available in Solar, universal AC or DC power configurations.
The inset light is available in either green or white with
optional IR (infrared). The IR component is continuously on or
switchable when integrated with an Avlite Lighting Control and
Monitoring System (LCMS).
Aviation obstruction lights are lighting devices attached
to tall structures: buildings, wind turbines, bridges etc. and
used as collision avoidance measures. Such devices make the
structure much more visible to passing aircrafts and is usually
used at night, although in some countries they are used in the
daytime also. Basically obstruction lights typically comes in
various intensities (low, medium, high) and either fixed or
Savvy Passenger Guide to Airport Lights
Colorful lights cover taxiways and runways to help pilots
navigate the airport. Red, blue, green, amber, and white lights
glow, flash, and race across the ground. It’s time to find out
what the colored airport lights mean and how pilots use them!
After an aircraft leaves the gate, the first challenge pilots
face is navigating the plane to the runway for takeoff. Both
day and night, airport lights make it easy to maneuver around
the maze of taxiways.
Blue Lights: Taxiway edge lights are always blue. The blue
taxi lights are easy to spot from the terminal and are often
the first airport lights seen by passengers. Blue taxiway
lights are typically illuminated after dark and during bad
weather. For many airports, the blue lights are all that is
necessary to mark the taxiways.
Green Lights: Green in-ground centerline lights are often
installed at busy airports and airports that experience bad
weather to enhance taxi guidance and safety. Unlike the blue
lights used to identify the taxiway edges, green centerline
lights are very bright. Pilots can see and follow them in the
worst weather conditions, day or night.
The tough metal housings for in-ground lights are mounted
flush with the surface of the taxiway. Only a small portion
protrudes above ground. The lights are installed a few inches
to the left or right of the actual painted centerline.
Although not technically
s, taxiway signs are well illuminated and easy to see.
Yellow and black signs identify taxiways. A black background
with yellow characters ( A3 ) identifies what taxiway the
aircraft is on. A yellow background with black characters ( A4
) identifies a crossing taxiway.
Red signs ( 31R ) always indicate a runway. The red color
reminds pilots not to proceed without permission from an air
Runway Guard Lights
In the last few years, new types of lights have been added to
enhance safety. One of the most prominent are Runway Guard
lights. Introduced in 1995, these flashing amber lights warn
pilots that they are about to taxi onto a runway.
The basic installation consists of a dual flashing light
unit. One unit is mounted on each side of the taxiway where the
aircraft must stop. Taxiing past guard lights onto the runway
requires a clearance from air traffic control.
In addition to the dual flashing units, wig-wags are often
installed in-ground, on the runway hold-short line. This system
is really helpful during low visibility conditions.
Red Stop Bar lights (also known as Runway Status Lights) are
another newcomer to the taxi light family. In an effort to
reduce the risk of deadly runway collisions, Stop Bar lights
are being installed at many airports world-wide.
The lights are placed along the hold-short line and are
switched on and off automatically. Unlike the yellow guard
lights which mean “use
caution,” red stop bar lights mean STOP – Don’t even THINK
about moving. When the lights are on, there is active traffic
on the runway or landing imminently. The lights must be
extinguished before an aircraft can proceed.
As of 2016, fifteen US airports have Runway Status lights
installed with more on the way. Look for them at busy
airports. They’re really bright; you can’t miss them.
Runways designed for low visibility operations (bad weather)
have a lot of lights.
Note that not all runways have the same light configuration.
The runway at St. Thomas, USVI, has only basic edge lighting
because the weather is usually gorgeous. Foggy San Francisco,
on the other hand, needs a full lighting system for low
