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).

       (2) Unserviceability markers must be placed at the entrance to, and across, any part of the movement area of an aerodrome (including a runway) that is not to be used by aircraft.
Note   See Chapter 9, Division 14, for lighting associated with closed and unserviceable areas.

       (3) At least 3 unserviceability markers must be displayed across the centreline of any portion of a taxiway, apron or holding bay that is unserviceable, whether or not it is possible for aircraft to safely taxi past the area that is unserviceable.

       (4) Any unserviceability markers must be appropriately secured or weighted against the hazards of jet blast, propeller wash or high winds.
        Note   CASA recommends that additional unserviceability markers be displayed, 3 m apart, continuously across the entire width of the runway, taxiway, apron or holding bay.

CHAPTER 8

Division 10 Obstacle markings

8.109 Obstacles and hazardous obstacles

       (1) The following objects or structures at an aerodrome are obstacles and must be marked in accordance with this Division unless CASA determines otherwise under subsections (3) and (5):

(a) any fixed object or structure, whether temporary or permanent in nature, extending above the obstacle limitation surfaces;

       Note   An ILS building is an example of a fixed object.

(b) any object or structure on or above the movement area that is removable and is not immediately removed.

       (2) An aerodrome operator must notify CASA in writing of all obstacles at the aerodrome.

       (3) CASA must assess each obstacle notified under subsection (2), and may determine in writing:

(a) that an obstacle is a hazard to aircraft (a hazardous obstacle); and

(b) what, if any, marking is required for the hazardous obstacle.

 (4) Details of hazardous obstacles, including their lighting and marking requirements, must be included in the aerodrome operator's aerodrome manual, unless CASA has made a determination under subsection (5).
 (5) CASA may determine in writing that a hazardous obstacle may remain unmarked because it is:

(a) sufficiently conspicuous in shape, size or colour; or

(b) shielded by another obstacle that is already marked; or

(c) lit by high-intensity obstacle lights by day and night.

       (6) Despite subsection (1), CASA may determine in writing, following an assessment:

(a) that an object or structure on, or within the immediate vicinity of, the aerodrome is a hazardous obstacle; and

(b) what, if any, marking is required for that hazardous obstacle.

8.110 Marking of hazardous obstacles

       (1) A hazardous obstacle, other than wires and cables, must be marked in a pattern
