markings are not required for a permanent taxiway closure if:

(a) an aircraft NO ENTRY sign is displayed at any entrance to the taxiway, as described in subsection 8.90 (1); and

(b) subsection 8.106 (4) is complied with for the taxiway; and

(c) for aerodromes available for night operations — a no entry bar is provided as described in section 9.108.

Note   CASA recommends that for non-permanent taxiway closures in excess of 5 days' duration at international aerodromes and aerodromes with frequent aircraft movements, taxiway unserviceability markings be used.

       (2) Unserviceability markings are not required for time-limited works if the works are otherwise in accordance with a method of working plan (MOWP) under section 15.02.

       (3) Unserviceability markings are not required for an unserviceable full-length runway at a controlled aerodrome if:

(a) lighted visual aids are used in place of unserviceability markings in the pattern described in subsections 9.128 (3) and (4); and

(b) the lighted visual aids are used for a maximum duration of 24 hours at which time unserviceability markings must be used.

       (4) Unserviceability markings on an unserviceable runway are not required if:

(a) for works occurring during hours of darkness — the closure does not extend for more than 45 minutes into the hours of following daylight; and
        Note   Daylight is defined as the period between the beginning of morning civil twilight and the end of evening civil twilight. See Chapter 3, Definitions etc.

(b) for all other works:

 (i) the runway unserviceability is of less than 24 hours' duration; and

 (ii) the total works period does not exceed 5 days' duration; and

 (iii) a NOTAM is issued;

        provided that:

(c) at a controlled aerodrome — ATC has been requested to broadcast information to aircraft regarding the runway unserviceability or the location of a displaced threshold; and

(d) at a non-controlled aerodrome — a vehicle used by a works safety officer supervising aerodrome works is equipped with a radio which allows for emergency 2-way communication with aircraft; and

(e) at any aerodrome, in the event of a total aerodrome closure — a total unserviceability signal, in accordance with the standards under section 8.104, is displayed in the aerodrome's signal area (if provided).
Note   24 hours is the maximum closure period before unserviceability markings are required. However, international aerodromes and aerodromes with frequent aircraft movements are recommended to display unserviceability markings within this period.

8.108 Use of unserviceability markers

       (1) Unserviceability markers must consist of a white standard cone:

(a) with a horizontal red stripe 25 cm wide around its centre halfway up the cone so as to provide 3 bands of colour, namely, white-red-white; and

(b) otherwise in accordance with subsection 8.07 (2).
