lights.

       (3) On a taxiway intended for use in visibility conditions of 350 m or greater, taxiway centreline lights must comply with the specifications set out in Figure 9.111 (1) or Figure 9.111 (2), whichever is applicable.

       (4) On a taxiway intended for use in visibility conditions less than 350 m, the taxiway centreline lights must have light intensity in accordance with Figure 9.111 (3), Figure 9.111 (4) or Figure 9.111 (5), whichever is applicable.

Note   Light units meeting the intensity standards shown in Figure 9.111 (3), Figure 9.111 (4) and Figure 9.111 (5), are specifically designed for use in low-visibility conditions. For the normal range of visibilities experienced most of the time in Australia, these lights, if operated on maximum intensity, would cause dazzle to pilots. If these lights are installed, CASA recommends that additional intensity control stages are provided, or that the maximum intensity at which they can be operated be otherwise limited.

9.91 Location of taxiway edge lights

       (1) Subject to subsection (2), taxiway edge lights must be located opposite to each other along both sides of a taxiway.

       (2) A taxiway edge light may be omitted if it would otherwise have to be located:

(a) on an intersection with another taxiway; or

(b) on a runway; or

(c) to facilitate taxiway curves with small radii.

       (3) Taxiway edge lights must be located outside the edge of the taxiway:

(a) equidistant from the centreline, except where asymmetric fillets are provided; and

(b) preferably 1.2 m from the taxiway edge, but no farther than 1.8 m, and no nearer than 0.6 m.

Note   Where a taxiway intersects with a runway, the last taxiway edge lights should preferably line up with the line of runway edge lights, and must not encroach beyond the line of runway edge lights (into the area outlined by the runway edge lights).

9.92 Spacing of taxiway edge lights

       (1) This section does not apply if any of the following make its application impossible:

(a) the alignment of the taxiway;

(b) the radius of the taxiway curve;

(c) the general taxiway environment;

        provided that a description and explanation of the limitation and its effects is recorded in the aerodrome manual.

       (2) Spacing of taxiway edge lights must be such that the edge lights are:

(a) clearly visible to pilots for an intended operation; and

(b) as far as possible, in accordance with Figure 9.92 (2).

       (3) On a curved section of taxiway, the taxiway edge lights must be spaced at uniform longitudinal intervals in accordance with Curve A in Figure 9.92 (2).

       (4) On a straight section of taxiway, the taxiway edge lights must be spaced at uniform longitudinal intervals not exceeding 60 m.

       (5)
