runways — Figure 9.75 (3);

 (ii) for 60 m wide runways — Figure 9.75 (4); and

(d) if located within 600 m from the runway end — show yellow with a minimum light intensity that is 0.4 times the intensity that would be in accordance with that shown in the following Figures in section 9.75:

 (i) for 30 m to 45 m wide runways — Figure 9.75 (3);

 (ii) for 60 m wide runways — Figure 9.75 (4); and

(e) have a light beam coverage that is toed-in towards the runway as follows:

 (i) for 30 m to 45 m wide runways — 3.5°;

 (ii) for 60 m wide runways — 4.5°.

       (2)  If omnidirectional circling guidance lights are used in conjunction with subsection (1), they must conform to subsection 9.51 (2).

9.54 Runway threshold lights

       (1) For a runway with runway edge lights, runway threshold lights must be provided.

       (2) Runway threshold lights must be located:

(a) in a straight line at right angles to the centreline of the runway; and

(b) when the threshold is at the extremity of a runway — as near to the extremity as possible and not more than:

 (i) 3 m outside the extremity; or

 (ii) 1 m inside the extremity; and

(c) when the threshold is a displaced threshold — at the displaced threshold with a tolerance of ± 1 m.

9.55 Pattern of runway threshold lights — non-instrument or non-precision approach runway

       (1) For a non-instrument, or non-precision, approach runway, runway threshold lights must consist of at least 6, equally spaced, unidirectional lights.

       (2) Despite subsection (1), if increased conspicuity of the runway threshold is desired for visual circling or circuit operations, then the runway edge lights, aligned with the threshold position, may be replaced by omnidirectional runway threshold lights on each edge.

Note   See Figure 9.76 (1) which illustrates the omnidirectional runway threshold lights option (green).

       (3) Runway threshold lights for a non-instrument, or non-precision, approach runway must be inset lights if:

(a) the threshold is a permanently-displaced threshold; or

(b) it is not possible for elevated lights to be installed.

       (4) For runways with a runway starter extension, the inset threshold lights may be aligned with the runway end light fittings in the reciprocal direction.

9.56 Pattern of runway threshold lights — precision approach runway

        For a precision approach runway, runway threshold lights must be spaced at equal intervals of no more than 3 m across the width of the runway.

9.57 Characteristics of runway threshold lights — non-instrument or non‑precision approach runway

        Runway threshold lights of low intensity or medium intensity must:

(a) be fixed; and

(b) be unidirectional; and

(c) show green in the direction of approach
