Division 13; and

(b) the A-VDGS is visible to the pilot at the dissection point and provides the pilot with positive guidance into the parking position.

9.81 Use of different types of taxiway lights

       (1) As far as possible, the provision of taxiway lights must be such that a taxiing aircraft is not required to alternate between taxiway edge and taxiway centreline lighting.

       (2) If any of the following:

(a) a rapid exit taxiway;

(b) a taxiway curve;

(c) a taxiway intersection;

(d) a narrower section of taxiway;

(e) a part of a taxiway;

        has taxiway centreline lights, and requires additional guidance to delineate the taxiway edges, then taxiway edge lights that comply with sections 9.91 to 9.93 may be used.

       (3) Despite subsection (1), taxiway edge and taxiway centreline lighting may be alternated on a temporary basis during periods of works on the affected taxiway.

9.82 Control of lights on taxiways

        On a standard taxi-route with runway lighting and taxiway lighting, the lighting systems must be interlocked to make simultaneous operation of both systems impossible.

9.83 Location of taxiway centreline lights

        Taxiway centreline lights must be:

(a) located along the centreline of the taxiway; or

(b) if offset from the centreline — uniformly offset by not more than 0.3 m.

Note   An offset of the taxiway centreline lights may be required to accommodate painting and maintenance of the taxiway centreline markings.

9.84 Spacing of taxiway centreline lights

       (1) Taxiway centreline lights on a straight section of a taxiway must be spaced at longitudinal intervals of not more than 30 m, except that:

(a) for taxiway sections with a length of 181 m or greater — longitudinal spacing intervals not exceeding 60 m may be used if this provides adequate guidance under the prevailing meteorological conditions; and

(b) on a taxiway intended for use in RVR conditions less than 350 m — the longitudinal spacing must not exceed 15 m.

       (2) When a taxiway changes from a straight to a curved section, the taxiway centreline lights must continue on from the preceding straight section at a uniform distance from the outside edge of the taxiway.

       (3) For taxiway centreline lights on a taxiway curve:

(a) the lights must be spaced at intervals such that a clear indication of the full extent of the curve is provided to the relevant pilot or ground vehicle pilot; and

(b) on a taxiway intended for use in visibility conditions less than 350 m — the spacing intervals must not exceed 15 m; and

(c) for use in visibility conditions less than 350 m on a curve with a radius of less than 400 m:

 (i) the spacing interval must not exceed 7.5 m; and
