Aerodrome Lighting Flashcards
Lights which are intensity adjustable
Approach lights Runway: Edge Threshold End Centre line Touchdown zone
Taxiway Center line
Aerodrome lights may be turned off as long as they can be turned on again within a period of
1 hour before eta of aircraft
If there is no back up power then emergency lights are required for
At least primary runway
Aerodrome beacons are
Watch out there’s a aerodrome here
Flashing
White and green = land
White and yellow = water
Can just flash white
Identification beacon
Aerodrome which is intended for use at night and can’t be easily identified
Green = land
Yellow water
What is the Calvert system
5 bars and a distance of codes centreline
What is a barrette
Groups of 3 or more lights arranged as a bar
What is a simple lighting system approach lights
Single centreline of lights out to 420m
single crossbar at 300m from threshold
Non instrument runways
Precision app cat I lighting system
Calvert system
Centreline out to 900m
1st 300m = single row of lights
2nd 300m = two rows of lights
3rd 300m = three rows of lights
5 crossbars
1sr crossbar at 150m from threshold
Yellow caution zone before stopway =cat I only
Precision approach cat II and III lighting system app lights
Differences from cat 1
Approach lights = first 300m = red / white barrettes
No yellow caution zone
White touchdown zone lights
Colour coded centreline:
900m from end = red and white
300m from end = red
PAPI is located
On left of runway
But for VM(C) = must be on both sides
APAPI = 2 lights instead of 4
Minimum eye height (MEHT)
Distance from pilots eyes to bottom of wheels
‘Eye to bottom of undercarriage’
VASIS
Like PAPI except 2 sets of 3 lights
Runway threshold / wingbar lights are to..
Showing green in direction of approach
Runway threshold identification lights
Non precision runway
Flashing white lights unidirectional in direction of the approach to runway
