10 CHARACTERISTICS OF A GOOD APPROACH LIGHTING SYSTEM Centerline guidance Roll guidance High intensity / controllable intensity Adequate length Sequenced flashers

11 “A” SERIES LIGHTING SYSTEMS BUILDING BLOCKS Centerline lights 1000’ Roll bar Side row bars 500’ Roll bar Termination bar Wing bars Sequenced flashers Runway Alignment Indicator Lights (RAILs)

12 Threshold lights ( A row of green lights on 5 foot centers extending across the runway threshold and outwards a distance of approximately 45 feet from the runway edges )

13 Centerline lights ( 13.5 feet wide with 5 evenly spaced lights ) 2400 feet long if glideslope is 2.75 deg or greater 3000 feet long if glideslope is less than 2.75 deg military field may be as short as 2000 feet

14 1000 ft roll bar 100 feet wide with 21 lights

15 “A” - SERIES APPROACH LIGHTING SYSTEMS Commonalties –Centerline lights –1000 ft roll bar

16 Sequenced flashing lights Flash in sequence toward the threshold at a rate of twice per second

17 Side Row bars ( 3 red lights each )

18 500 ft roll bar ( 1 additional bar each side of the 500’ centerline bar with 4 lights each )

19 A ALSF - 2

20 ALSF 2? It’s for Cat II & III approaches.

21 Basic building blocks

22 Sequenced flashing lights

23 Remove light bars at 100 and 200 feet

24 Termination bar 50 feet wide with 11 red lights

25 Wing bars or pre-threshold bars ( 5 red lights each )

26 ALSF - 1 A1

27 First 1500 ft of ALSF-1

28 SALSF A2

29 SALS A2

30 Basic building blocks

31 Short (First 1500 ft)

32 Simplified (spacing goes to 200 ft) 1000’ roll bar only has 15 lights Last centerline light at 1400 ft
