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
Runway lead-in lights
Visual guidance along a specific approach
3 flashing white lights
Should flash in sequence towards the runway
Circling guidance lights
When runway lighting does not identify runway to aircraft doing circling approach
May be fixed or flashing white
Taxiway lighting is
Edge = blue
centre line = green
When is taxiway lighting alternating green and yellow
Inside ils sensitive area
High speed exits
Stopbars are used
When RVR is less than 350m
Intermediate holding position lights
3 fixes unidirectional yellow lights
Runway guard lights
Only saying “careful you’re near a runway”
RVR less than 550m
Flash yellow
