General

1.1

All aeronautical ground lights shall be operated

a) during the time from sunset to sun rise;

b) during time from sunrise to sunset when visibility is 3000 m or less; less than 5 KM.

c) when requested by pilot;

d) at any other time when their use, based on meteorological conditions, is considered desirable for the safety of air traffic.

1.2

Lights on and in the vicinity of aerodromes that are not intended for en-route navigation purposes may be turned off, subject to further provisions hereafter, if no likelihood of either regular or emergency operation exists, provided that they can be again brought into operation at least one hour before the expected arrival of an aircraft.

1.3

At aerodromes equipped with lights of variable intensity a table of intensity settings, based on conditions of visibility and ambient light, should be provided for the guidance of air traffic controllers in effecting adjustment of these lights to suit the prevailing conditions. When so requested by an aircraft, further adjustment of the intensity shall be made whenever possible.

2.

Approach lighting

Note. -- Approach lighting includes such lights as simple approach lighting systems, precision approach lighting systems, visual approach slope indicator systems, circling guidance lights, approach light beacons and runway alignment indicators.

2.1

Approach lighting shall also be operated:

a) during the time from sunset to sun rise;

b) during time from sunrise to sunset when visibility is 3000 m or less;

c) when requested by pilot;

d) at any other time when their use, based on weather conditions, is considered desirable for the safety of air traffic;

e) when the associated runway lighting is operated.

2.2

The lights of a visual approach slope indicator system shall be operated during the hours of daylight as well as of darkness and irrespective of the visibility, when the associated runway is being used.

3.

Runway lighting

Note. -- Runway lighting includes such lights as edge, threshold, centre line, end, touchdown zone and wing bar lights.

3.1

Runway lighting shall not be operated if that runway is not in use for landing, take-off or taxiing purposes, unless required for runway inspections or maintenance.

3.2

If runway lighting is not operated continuously, lighting following a take-off shall be provided as specified below:

a) at aerodromes where air traffic control service is provided and where lights are centrally controlled, the lights of one runway shall remain lighted after take-off as long as is considered necessary for the return of the aircraft due to an emergency occurring during or immediately after take-off;

b) at aerodromes without air traffic control service or without centrally controlled lights, the lights of one runway shall remain lighted until such time as would normally be required to reactivate the lights in the likelihood of the departing aircraft returning for an emergency landing, and in any case not less than fifteen minutes after take-off.

4.

Stopway lighting

4.1

Stop way lights shall be operated whenever the associated runway lights are operated.

5.

Taxiway lighting

Note. -- Taxiway lighting includes such lights as edge lights, Centre line lights, stop bars and clearance bars.

5.1

Where required to provide taxi guidance, taxiway lighting shall be turned on in such order that a continuous indication of the taxi path is presented to taxiing aircraft. Taxiway lighting or any portion thereof may be turned off when no longer needed.

6.

Stop bars

6.1

Stop bars shall be switched on to indicate that all traffic shall stop and switched off to indicate that traffic may proceed.

Note. -- Stop bars are located across taxiways at the point where it is desired that traffic stop, and consist of lights, showing red, spaced across the taxiway.

7.

Obstacle lighting

7.1

Obstacle lighting associated with the approach to or departure from a runway or channel, where the obstacle does not project through the inner horizontal surface should be turned off and on simultaneously with the runway lights.

7.2

Un -serviceability lights may not be turned off as permitted under 1.2 while the aerodrome is open.
