Q

Why would an aerodrome beacon be provided at an aerodrome operating at night?

A

If the level of background lighting, surrounding terrain, proximity of other ADs or lack of navaids would make the AD difficult to identify.

Q
  1. ) What would 4 white lights on a PAPI indicate?
  2. ) What colour lights would a PAPI show if you were on the glide slope?
  3. ) What would 4 red lights on a PAPI indicate?
A
  1. ) That you are above the glide slope.
  2. ) 2 white lights followed and 2 red lights.
  3. ) That you are below the glide slope.

Q

Except for red side barrettes (where provided) what colour is approach lighting?

A

White

17
Q

For CAT II/III approaches, what supplementary lighting is normally installed and why?

A

Centreline barrettes and 2 rows of red side barrettes in order to provide the pilot with enhanced visual cues over the last 300m of the approach.

18
Q

What lights do all runways licensed for night use have?

A

RWY edge lights and RWY threshold and end lights

19
Q

What additional lights do runways where low visibility operations take place have?

A

RWY centreline lighting and touchdown zone lighting.

20
Q

What colour is runway edge lighting?

A

White except for:

  • Caution zone lighting which is yellow.
  • Pre threshold lighting which is red.
  • RWY exit lighting which is blue.
  • Stopway lighting which is red.
21
Q

What colours are runway threshold and runway end lighting and what do they indicate?

A

RWY threshold lighting is green and indicates the start of the available landing distance. May include green threshold wing bars.

RWY end lighting is red and indicates the extremity of the RWY that is available for manoeuvring.

NB: Pilots should not land before the threshold lights, nor continue landing or taxi beyond the RWY end lights.

22
Q

How are runway centreline lights colour coded?

A

In order to warn a pilot of the approaching end of the RWY.

White lights extend from the threshold to 900m from the RWY end.
The following 600m is lit with alternating red and white lights.
The final 300m is lit with red lights.

23
Q

Describe touchdown zone lighting

A

Consists of 2 rows of white barrettes either and provides textural cues in the touchdown area. They extend from the threshold either for 900m or the midpoint of the RWY, whichever is the lesser distance.

24
Q

Describe rapid exit taxiway lights.

A
  • Provide pilots with distance to go information to the nearest rapid exit TWY on the RWY.
  • Consist of six yellow lights adjacent to the RWY centreline and configured in a 3/2/1 pattern spaced 100m apart. The single light is 100m from the start of the turn for the rapid exit TWY.
  • Enhance situational awareness in low visibility and enable pilots to apply braking action for more efficient roll out and RWY exit speeds.
25
Q

What colour are taxiway edge lights and the lights which mark edge of aprons, turning and holding areas?

A

Blue

26
Q

What colour are taxiway centreline lights? (used at aerodromes equipped for low visibility operations)

A

Green

27
Q

What colour are stop bar lights when lit and when shall they be operated?

A

Red

Whenever associated RWY lights are operated. They shall be switched on to indicate that all traffic shall stop and off to indicate traffic may proceed.

28
Q

What colour are lead on lights?

A

Green

29
Q

What are runway guard lights?

A

Pairs of alternately flashing yellow lights located on each side of a TWY and provide a warning of close proximity to the RWY.

30
Q

When shall all aeronautical be operated?

A
  • Continuously during darkness.
  • At any other time when their use, based on meteorological conditions is considered desirable for the safety of air traffic.
31
Q

What is the purpose of the table of lighting intensity settings?

A

To provide guidance to ATCOs at aerodromes equipped with lights of variable intensity in effecting adjusting lights to suit prevailing conditions.

32
Q

What are the maximum switchover times for aerodrome lighting systems from the main power supply to a secondary power supply?

A
  • Approach lights, RWY lights and major TWY lights = MAX 15 seconds.
  • Approach lights for CAT II/III = MAX 1 second
