(1) Subject to subsection (2), runway guard lights must be either:

(a) elevated runway guard lights on each side of the taxiway (Configuration A); or

(b) in-pavement runway guard lights across the taxiway (Configuration B).

       (2) Both elevated and in-pavement runway guard lights must be used together when increased conspicuity of the taxiway/runway intersection is required, for example:

(a) if holding position markings do not extend straight across the taxiway; or

(b) on a wide taxiway, if elevated lights on both sides of the taxiway are not within the normal field of view of a pilot approaching the runway guard lights.

       (3) Elevated runway guard lights must be located:

(a) on both sides of the taxiway at the runway holding position closest to the runway, and

(b) equidistant from the taxiway centreline; and

(c) not less than 3 m, and not more than 5 m, outside the edge of the taxiway.

       (4) In-pavement runway guard lights must be located:

(a) across the entire taxiway, including fillets and holding bays; and

(b) at the runway holding position closest to the runway; and

(c) with the lights spaced at uniform intervals of 3 m.

9.100 Characteristics of runway guard lights

       (1) Configuration A runway guard lights must consist of a pair of elevated lights showing yellow on each side of the taxiway.

       (2) Configuration B runway guard lights must consist of inset lights showing yellow across the taxiway.

       (3) The performance of Configuration A runway guard lights must comply with the following requirements:

(a) the lights in each pair must be illuminated alternately at between 30 and 60 flashes per light per minute;

(b) the light suppression and illumination periods of each light in a pair must, if possible, be of equal and opposite duration;

(c) the light beams must to be unidirectional and aimed so that the beam centres cross the taxiway centreline at a point 60 m before the runway holding position;

(d) the effective intensity of the yellow light and beam spread must be the same as that in the specifications in Figure 9.111 (6).

       (4) The performance of Configuration B runway guard lights must comply with the following requirements:

(a) the lights must illuminate as a single unit of lights but with adjacent lights flashing alternately at between 30 and 60 flashes per minute;

(b) the light suppression and illumination periods of each light must, if possible, be of equal and opposite duration;

(c) the light beams must be unidirectional and aligned so as to be visible to the pilot of an aeroplane taxiing to the holding position;

(d) the effective intensity of the yellow beam and beam spread must be the same as that in the specifications
