AIRPORT LIGHTING
FACTORS AFFECTING AIRPORT
LIGHTING:
• Airport classification
• Amount of traffic
• Availability of power
• Nature of aircraft using the airport
• Type of night operation plans
• Type of landing surfaces provided
• Weather condition, etc.
(contd.)
• To achieve uniformity and to guide pilots for
unfamiliar airports, colours and general
arrangement of airport lights are standardized.
• Airport lights are kept clean, well-maintained,
checked regularly for faulty bulbs and
replacement.
• Tough and laborious job, major airport contains
30,000 lights
• Provision of emergency power supplies, which
can take over in seconds in case of any power
failure.
ELEMENTS OF AIRPORT LIGHTING:
• Airport beacon
• Approach lighting
• Apron and hangar lighting
• Boundary lighting
• Lighting of landing direction indicator
• Lighting of wind direction indicator
• Runway lighting
• Taxiway lighting
• Threshold lighting
1) AIRPORT BEACON:
• Beacon- strong beam of light- used to indicate any
geographical location- situated slightly above the
horizontal- rotated to produce flashing light to an
observer.
• It gives out white and green flashes in the horizontal
directions 180◦ apart. Flashes are visible for the
pilot from any direction of approach and it
indicates the approximate situation of an airport
equipped for the night operations.
• Rotates at six revolutions per minute- mounted at
top of terminal building or hangar.
(contd.)
• Obstruction not cleared yet- then separate
tower is provided for installation of rotating
beacon.
• Code beacon- indicates light provided
sufficiently high to clear all obstructions.
• It consists of two 500 watts bulb with green
colour screen.
• Continuously flashes a Morse code signal
designating the airport.
Airport Beacon Lighting:
APPROACH LIGHTING:
• Before runway begins- sequence of high-
intensity lighting arrangement for a length of
900m.
• Helps pilots to check if the aircraft is centered
correctly of not.
• Gives way to touchdown zone lights from
threshold of the runway.
• Normally mounted on pedestals-varying
heights-to accommodate any irregularities in
ground- ensuring the lights themselves are in
(contd.)
Arrangements adopted for approach lightings:
1) Calvert system
2) ICAO system
1) Calvert system:
• Widely used in Europe and other parts of the
world.
• Developed by E.S.Calvert in Great Britain.
• In this, there are six transverse rows of lights
of variable length placed at a c/c distance of
15om.
• In this, the roll guidance is principally provided
by the transverse rows of lights.
