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

5. 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

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

12. 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

13. Visual Approach Slope Indicators VASI

14. VASI contd.. Below glide path On glide path Above Glide path Far Bar Near Bar Red White

15. 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
