A barrette and spacing
Groups of 3 or more lights arranged as a bar
Each bar = 150m spacing up to 900m
Single app lighting system spacing of the cross bar and distance of the centreline lights
Single centreline lights out to 420m
Single crossbar 300m from the t/hld
CAT 1 app lighting structure
Yellow caution zone at the end
Centreline out to 900m - all fixed, variable white - 1st 300m = 1 line , 2 lines to 600m, 3 lines to 900m
5 crossbars 150m apart
CAT 2 and CAT 3 app lights diff from CAT 1
Supplementary app lights for the 1st 300m red and white barrettes
No yellow caution area
Touchdown zone lights - 900m
Colour coded centreline at the end of the r/y
PAPI and definition
Precision app path indicators
A wing bar of 4 lights uniformly spaced
APAPI
2 lights instead of 4
MEHT measured from and its purpose
Min eye height
Eye to the bottom of the undercarriage
Assesses the usability of the PAPIs
VASIS and what doe they consist of
Visual app slope indicator system
2 sets of 3 lights - pilot on the glide slope - 1st set of lights appears white and the 2nd set appears red
R/y edge lights colour
Variable intensity white showing in the direction from which the app are made
Pre t/hld (displaced t/hld) = red in the app direction
R/y t/hld and wing bar lights colour
Fixed unidirectional showing green in the direction of the app to the r/y
R/y t/hld identification lights
Used for a non precision r/y
Flashing white lights unidirectional in the direction of the app to the r/y
R/y end lights
Fixed, unidirectional showing red in the direction of the r/y
R/y centreline lights
Fixed, variable intensity white
CAT 2 and 3 - last 900m, shown as alternate red and white
Touchdown zone lights
Fixed, unidirectional, variable intensity white
Stopway lights

R/y lead in lights
Groups of at least 3 flashing white lights - should flash in sequence to the r/y
Circling lights, guidance
Fixed, flashing white
T/y lighting
Edge = blue
Centreline = green
Stop bars are used when the RVR
Is less than 350m
Intermediate holding posn lights
3 fixed unidirectional showing yellow
Road holding posn lights
Either
Controllable red (stop) or green (go)
Or
Flashing red lights
R/y guard lights are fitted when and the colours
At the entrance of a r/y when the RVR is less than 550m -stop bar is not fitted
