This is a introductory presentation for airfield lighting that created by Milten Jose Airfield Engineer, AMAINDIA PVT. LTD. for Mumbai international airport limited.

8. Runway Edge Lights are used to outline the edges of runway during periods of darkness or
restricted visibility conditions. These lighting systems are classified according to the intensity.
They are capable of producing different level of illumination based on weather condition.

9. The Precision Approach Path Indicator
(PAPI) is a light system positioned beside the
runway that consists of four boxes of light units
on each side of Approach, that provide a visual
indication of a fixed-wing aircraft position on
the glide path for the associated runway.
The PAPI is usually located on the left side of
the runway and can be seen up to five nautical
miles during the day and twenty miles at night.

10. Each PAPI light unit is equipped with an optical apparatus that splits
light output into two segments, red and white. Depending on the angle
of approach, the lights will appear either red or white to the
pilot.(usually 3 degrees)

11. Before the runway actually begins, there is a sequence of high-
intensity lighting at a maximum length of 900 meter. The Pilot can see
from these Approach lights whether his aircraft is centered correctly.
These lights then give way to the Touchdown zone lights from the
Threshold of the Runway.
The Approach lights are normally mounted on pedestals of
varying height to accommodate any regularities in the ground
ensuring that the lights themselves are always level. They are
designed to give way if accidently hit (Frangible).

12. APPROACH INSET APPROACH INSET
• SIDE ROW • CENTER ROW

13. The beginning portion of runway is used for landing which is called
Threshold. The Threshold lights show green from the approach side. The
identification of the Threshold is a major factor for the decision of the pilot
to land or not to land. They are placed on a line at right angles to the
runway axis as near to the end of the runway and, at 3 m outside the end.
Threshold lights are usually placed along the full width of the runway, also
may contain wing bars which shall be symmetrically disposed about the
runway center line at the threshold in two groups. Each wing bar shall be
formed by at least five lights

14. Runway center line lights shall be located along the center line of the
Runway. The lights shall be located from the threshold to the end at
longitudinal spacing of approximately 15m.
Runway center line lights shall be fixed
lights showing variable white from the
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 red 300 m to
the runway end.

15. Defines the landing portion of the Runway. Two rows of transverse light bars (barrettes) located
symmetrically about the runway centre line.
Each barrettes composed of at least three lights which are white in color. Touch down Zone
lights are white in color & shall extend from the threshold for a longitudinal distance of 900 m.

16. The Pilots have to maneuver the aircrafts on a system of taxiways to and from the terminal
and hangers areas either after a landing or on the way to take off. Taxiway system in Mumbai
Airport is very complex and it becomes necessary to provide adequate lighting aids.

17. RUNWAY 09-27

19. Runway guard lights are yellow lights used to warn pilots and drivers of
vehicles when they are operating on taxiways, that they are about to enter
an active runway. The lights are flashing type having a flashing rate
between 30 and 60 cycles per minute. The Runway Guard lights are
components of an advanced surface movement guidance and control
system.

20. Sign boards are provided to convey a mandatory instruction,
information on a specific location or destination on a
movement area or to provide other information to meet the
requirements.

21. There are six types of Airport Signs:
Mandatory Instruction Signs – red background with white inscription. They denote an
entrance to a runway (numbers), critical area (ILS), or prohibited area.
Location Signs – black with yellow inscription and yellow border. It will not have any
arrows. They identify a taxiway or runway location, to identify the boundary of the
runway, or identify an instrument landing system (ILS) critical area.
Direction Signs – yellow background with black inscription. They identify the
designation of the intersection taxiway(s) leading out of an intersection.
Destination Signs – yellow with black inscription and also contain arrows. They
provide information on locating things, such as runways, terminals, cargo areas, and
civil aviation areas.
Information Signs – yellow background with black inscription. They provide pilot with
information on things as areas that con not be seen from the control tower, applicable
radio frequencies, and moise abatement procedures.
Runway Distance Remaining Signs – black background with white numbers. The
numbers indicate the distance of the remaining runway in thousands of feet.

tool for GVK & amaindia staffs to build a
better professional work culture in daily
activities.

slides may not be the precise of MIAL
