Objects to be marked and/or lighted
Note – The marking and/or lighting of obstacles is intended to reduce hazards to aircraft by indicating the presence of the obstacles. It does not necessarily reduce operating limitations which may be imposed by an obstacle.
6.1.1 A fixed obstacle that extends above a take-off climb surface within 3000 m of the inner edge of the take-off climb surface shall be marked and, if the runway is used at night, lighted, except that:
a) such marking and lighting may be omitted when the obstacle is shielded by another fixed obstacle;
b) the marking may be omitted when the obstacle is lighted by medium-intensity obstacle lights, Type A, by day and its height above the level of the surrounding ground does not exceed 150 m;
c) the marking may be omitted when the obstacle is lighted by high-intensity obstacle lights by day; and
d) the lighting may be omitted where the obstacle is a lighthouse and an aeronautical study indicates the lighthouse light to be sufficient.
6.1.2 fixed object, other than an obstacle, adjacent to a take-off climb surface shall be marked and, if the runway is used at night, lighted if such marking and lighting is considered necessary to ensure its avoidance, except that the marking may be omitted when:
a) the object is lighted by medium-intensity obstacle lights, Type A, by day and its height above the level of the surrounding ground does not exceed 150 m; or
b) the object is lighted by high-intensity obstacle lights by day.
6.1.3 A fixed obstacle that extends above an approach or transitional surface within 3000 m of the inner edge of the approach surface shall be marked and, if the runway is used at night, lighted, except that:
a) such marking and lighting may be omitted when the obstacle is shielded by another fixed obstacle;
b) the marking may be omitted when the obstacle is lighted by medium-intensity obstacle lights, Type A, by day and its height above the level of the surrounding ground does not exceed 150 m;
c) the marking may be omitted when the obstacle is lighted by high-intensity obstacle lights by day; and
d) the lighting may be omitted where the obstacle is a lighthouse and an aeronautical study indicates the lighthouse light to be sufficient.
6.1.4 A fixed obstacle above a horizontal surface shall be marked and, if the aerodrome is used at night, lighted except that:
a) such marking and lighting may be omitted when:
1) the obstacle is shielded by another fixed obstacle; or
2) for a circuit extensively obstructed by immovable objects or terrain, procedures have been established to ensure safe vertical clearance below prescribed flight paths; or
3) an aeronautical study shows the obstacle not to be of operational significance;
b) the marking may be omitted when the obstacle is lighted by medium-intensity obstacle lights, Type A, by day and its height above the level of the surrounding ground does not exceed 150 m;
c) the marking may be omitted when the obstacle is lighted by high-intensity obstacle lights by day; and
d) the lighting may be omitted where the obstacle is a lighthouse and an aeronautical study indicates the lighthouse light to be sufficient.
6.1.5 A fixed object that extends above an obstacle protection surface shall be marked and, if the runway is used at night, lighted.
Note – See 5.3.5 for information on the obstacle protection surface.
6.1.6 Vehicles and other mobile objects, excluding aircraft, on the movement area of an aerodrome are obstacles and shall be marked and, if the vehicles and aerodrome are used at night or in conditions of low visibility, lighted, except that aircraft servicing equipment and vehicles used only on aprons may be exempt.
6.1.7 Elevated aeronautical ground lights within the movement area shall be marked so as to be conspicuous by day. Obstacle lights shall not be installed on elevated ground lights or signs in the movement area.
6.1.8 All obstacles within the distance specified in Table 3-1, column 11 or 12, from the centre line of a taxiway, an apron taxiway or aircraft stand taxi lane shall be marked and, if the taxiway, apron taxiway or aircraft stand taxi lane is used at night, lighted.
6.1.9 Obstacles in accordance with 4.3.2 shall be marked and lighted, except that the marking may be omitted when the obstacle is lighted by high-intensity obstacle lights by day.
6.1.10 Overhead wires, cables, etc., crossing a river, valley or highway shall be marked and their supporting towers marked and lighted if an aeronautical study indicates that the wires or cables could constitute a hazard to aircraft, except that the marking of the supporting towers may be omitted when they are lighted by high-intensity obstacle lights by day.
6.1.11 When it has been determined that an overhead wire, cable, etc., needs to be marked but it is not practicable to install markers on the wire, cable, etc., then high-intensity obstacle lights, Type B, shall be provided on their supporting towers.
