Airport lighting provides guidance for aircraft during takeoff, landing, and taxiing at night or in low visibility conditions. There are different types of lights including approach lighting, taxiway lighting, runway lighting, and general airport lighting. Airport lighting consists of edge lights, centerline lights, indicator lights, and beacon lights of various colors that help pilots navigate the airfield safely. The specific lighting configuration depends on factors like the airport's classification, traffic levels, and weather conditions.

airfield to guide aircraft
in taking off or landing
during night
As a guide to pilot
Emergency power

TYPES OF AIRPORT
LIGHTING

4. 1.General Airport Lighting
Includes Beacon Lights on top of tower,
buildings
The Airport Beacon : large, powerful rotating
light highly visible from miles away
Rotate green and white
Steady red beacon on top of airport building to
aid in collision avoidance for low-flying
aircraft.

5. At Heliports Beacon:
White and Yellow rotating light
At airports Beacon:
White and Green rotating light

6. 2. Taxiway Lighting
Taxiway Edge Lights: Blue, Lines taxiway
Taxiway Center Light: Green Light
Clearance Bar Lights: Steady yellow, visibility
of hold line
Stop Bar Lights: Steady red, ATC in low
visibility situation, across taxiway at hold short
line
Runway Guard Lights: A pair of two steady
yellow light at hold short line, may be flashing

7. Taxiway edge light
Taxiway centerline light
Clearance Bar lights
Steady Bar lights
Runway Guard light

8. 3.Runway Lighting
Runway End Identifier Lights: white flashing
light one on each side of approach end of
runway
Runway Edge Light Systems
(HIRL/MIRL/LIRL):steady white light on
edges of runway
Runway Centerline Lighting System (RCLS)

9. 3.Runway Lighting (Contd..)
Touchdown Zone Lights (TDZL) : Define
landing portion of runway, Up to midpoint
Land and Hold Short Lights (LAHSO)
Runway status light or Runway entry light
(REL)

RCLS

14. 4.Approach Lighting
An approach lighting system or ALS, is a
lighting system installed on the approach end
of an airport runway
Consisting of a series of light bars, strobe
lights, or a combination of the two that extends
outward from the runway end

16. 4.Approach Lighting contd..
Visual glide slope indicators
Visual guide to pilot during descent to maintain
stabilized approach
This includes:
VASIs, or Visual Approach Slope Indicators:
lights indicating aircraft is too high or too low
on approach
PAPI, or Precision Approach Path Indicator

20. Factors Affecting Airport Lighting
Airport classification
Availability of power
Amount of traffic
Nature of aircraft
Type of night operation plan
Type of landing surface provided
Weather condition
