SPECIAL ILLUMINATION SYSTEM
Ground Lights Detail:
Precision Approach Lighting
System ( 06 direction ) :
The approach lighting system consists of a
row of lights on the extended centre line of runway and displaced
900 m from runway threshold. The approach lights have been
placed at longitudinal intervals of 30 m from the threshold.
The approach lighting system has two crossbar
lights. First crossbar light has been placed 150 m away from
the threshold. First crossbar has filled in the gaps between
the centre line and side row lights. The second crossbar has
been placed 300 m away from the threshold and it is extended
on both sides of the centre lights to a distance of 15 m from
the centre line.
The side row lights has been placed on each
side of the centre line at longitudinal spacing equal to the
centre line lights and first light located 30 m away from
the threshold.The lateral spacing between the inner lights
of side rows are 18 m , which is the same a spacing for the
touchdown zone lights.
Barrettes are 4,5 m long and intervals of
uniformly spaced light sources are 1,5 m. Barrettes beyond
300 m from the threshold are equipped with capacitor discharge
light. Each discharge light flashes twice a second in second. Electrical
circuits of the capacitor discharce light are operated independently
from the other lighting systems.
Approach Lighting System ( 24 direction
) :
The approach lighting system
consists of a row of lights on the extended centre line of
runway 900 m from runway threshold. The approach lights have
been placed at longitudinal intervals of 30 m from the threshold. Row
of lights are 4,5 m long and intervals of uniformly spaced
light sources are 1,5 m.
The approach lighting system has a crossbar
light.It has been placed 300 m away from threshold.
Runway Touchdown Zone Lights
( 06 direction ) :
Touchdown zone lighting system consists of a row of lights
on the extended from the threshold for a longitudinal distance
of 900 m on runway.
Each row of lights has been composed of at
least 3 lights with spacing between 1,5 m. The longitudinal
spacing between row of lights is 30 m. The lateral spacing
between inner lights of side touchdown zone lights is 18 m.All
lights has been fixed, unidirectional lights showing white.
Runway Centre Line Lighting
System :
Runway centre line lights have been located along 50 cm uniformly
offset to the same side of the centre line of runway. The lights
are located from the threshold to the end at longitudinal
spacing of 15 m. Runway centre lights are fixed lights showing
variable white from threshold to the point 900 m from the
runway end, alternate red and variable white from 900 m to
300 m from the runway end , and red from 300 m to the runway
end.
Runway End Lights :
Runway end lights have been placed on a line at right angles
to the runway centre line. Runway end lighting system consists
of eight lights. Lights are symmetrically disposed about the
centre line in two groups with the lights uniformly spaced
in each group. The spacing between runway end lights in each
group is 5,85 m.
Runway Edge Lights :
Runway edge lights are placed along the full length of the
runway.Intervals of uniformly spaced lights are 60 m.
Runway edge lights are fixed lights showing
white, except that a section of the lights 600 m of the runway
length from the end at which the take-off run is started showing
yellow.
Taxiway Centre Line Lights
:
Taxiway centre line lights are located on an exit taxiway,
taxiway, apron and between runway centre line. Taxiway centre
line lights are fixed lights showing green. The lights (alternate
taxiway center light) which placed near the runway centre
line are fixed and showing green and yellow.
Taxiway centre lights are located on the taxiway
centre line and spaced at longitudinal interval between lights
, min.50,42 m ,max.58 m.
Taxiway centre line lights on rapid exit taxiway
are located between runway and taxiway centre line. It's commence
at a point at least 60 m before the beginning of the taxiway
centre line curve and continue intersection of end of curve
and centre line of taxiway where an aeroplane reach normal
taxiing speed. The light on that portion parallel to the runway
centre line has been placed at least 60 cm from the runway
centre line lights. Taxiway centre lights on rapid exit taxiway
has been spaced at longitudinal intervals 14,26 m and 15,09
m.
Taxiway Edge Lights :
Taxiway edge lights are placed along the full length of taxiway. Intervals
of the lights which placed straight side of taxiway is between
37 m and 60 m. Taxiway lights are fixed, elevated type lights
and showing blue.
Interval of the lights which placed curve
parts of the taxiway are between 7,5 m and 15 m. This lights
are fixed, embedded type lights and showing blue.
Stop Bars :
The stop bars are located across the taxiway at the point
where it is desired that traffic stops. Stop bars are consist
of lights spaced at intervals of 3 m across the taxiway, showing
red in the intended direction of approach to intersection
point.
Each end of the stop bar is equiped with a
pair of elevated type lights for where the normal stop bar
lights might be obscured by snow, position or structure of
aircraft.
Guard Lights :
Each taxiway and runway intersections has been equipped with
guard lights. System consists of two pair of flashing yellow
lights.
Threshold Lights :
Threshold lights has been placed on a line at right angle
to the runway centre line. System consists of 16 lights. Threshold
lights has filled in the gaps between runway edges.
Threshold lights are fixed and showing green. The
lights are spaced uniformly and inteval of lights not more
then 3 m.
REIL :
REIL has been located symmetrically about the centre line
, in the line with the threshold and 10 m outside each line
of runway edge lights. REIL has been visible only in the direction
of approach to the runway and flashing white lights.
PAPI :
The system consists of wing bar of 4 lamp units equally spaced
( 9 m. ). Wing bar has been located on both side of the runways.
Each light unit has been capable of adjustment in elevation
between 1.30 and 4.30 above the horizontal.
PAPI system has been placed closely with glide path of ILS
and adjusted 3.50 above the horizontal.
Identification Beacon :
An identification beacon has been located top of the aerodom
control tower for use at night. It is showing flashing green
and white.
Wind Direction Indicator
:
A wind direction indicator has been located left side of runway
(06 direction) for visible from aircrafts in flight and to
be free from the effect of air disturbances caused by nearby
objects. It has been illuminating for use at night.
Landing Direction Indicator
:
A landing direction indicator has been located left side of
runway (06 direction) for visible from aircrafts in flight
It has been illumminating for use at night.
Signalling Lamp :
A signalling lamp has been provided in aerodrom control tower. It
has been capable of producing red, green and white signal
light. It is suitable for requirements of Annex 14.
