       (6) Where the taxiway centreline lights cross an intersecting runway, the colour of the taxiway centreline lights viewed by a pilot of an aircraft entering the runway from the taxiway must be:

(a) green up to the runway centreline; and

(b) alternately green and yellow beyond the runway centreline while exiting on the other side of the runway; and

(c) not visible to a pilot located on the runway centreline.

9.89 Rapid exit taxiway indicator lights

       (1) Rapid exit taxiway indicator lights (RETIL) may be provided on a runway intended for use in RVR conditions less than 350 m or where the traffic density is heavy.

       (2) If provided, RETIL must be displayed in the pattern shown in Figure 9.89 (2).

       (3) If provided, RETIL must not be displayed if any lamp or other failure of the lights prevents the display of the full light pattern as shown in Figure 9.89 (2).

       (4) If provided, a set of RETIL must be located on the runway on the same side of the runway centreline as the associated rapid exit taxiway, in the configuration shown in Figure 9.89 (2).

       (5) Each set of RETIL must be located 2 m apart from each other set, and the lights nearest to the runway centreline must be displaced 2 m from the runway centreline.

       (6) Where more than one rapid exit taxiway exists on a runway, the set of RETIL for each exit must not overlap when displayed.

       (7) If provided, RETIL must be fixed, unidirectional, yellow lights, aligned so as to be visible to the pilot of a landing aeroplane in the direction of approach to the runway.

       (8) If provided, the light intensity of RETIL must be in accordance with the specifications in Figure 9.75 (8) or 9.75 (9), as appropriate.

Note   CASA recommends that RETIL be supplied with power on a separate circuit to other runway lighting so that they may be used when other lighting is switched off.

9.90 Beam dimensions and light distribution of taxiway centreline lights

       (1) The beam dimensions and light distribution of taxiway centreline lights must be such that the lights are visible only to the pilot of an aircraft on, or in the vicinity of, the taxiway.

       (2) The light distribution of the green taxiway centreline lights in the vicinity of a threshold must be such as not to be confused with the runway threshold 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
