CHAPTER 8

Division 2 Markers

8.06 Introduction

       (1) A marker must be lightweight and frangible in accordance with Division 11 of this Chapter.

       (2) When displayed, a marker must be secured against propeller wash and jet blast to ensure it does not cause a hazard to aircraft.

8.07 Cones

       (1) A cone used as runway edge marker or a taxiway edge marker must:

(a) be 0.3 m high; and

(b) have a base diameter of 0.4 m.

       (2) A cone used other than as a runway edge marker or a taxiway edge marker must:

(a) be 0.5 m high; and

(b) have a base diameter of 0.75 m; and

(c) be placed to provide not less than 0.1 m of vertical clearance from the bottom of the vertical propeller or engine pod of the aircraft:

 (i) that is regularly using the aerodrome; and

 (ii) whose propeller or pod is closest to the ground of the aircraft which the runway is appropriately nominated by the aerodrome operator to serve.

       (3) A cone mentioned in a row of column 1 of Table 8.07 (3)-1 must be in the colour or colours mentioned in column 2 that is for the same row, and be as illustrated in Figure 8.07 (3)-2.

Runway strip marker                        White
Helicopter apron edge marker               Blue
Helicopter taxiway edge marker             Blue
Unserviceability marker                    White, with central 25 cm red band
Runway strip marker (displaced threshold)  Split white and suitable background colour

8.08 Works limit markers

       (1) Works limit markers must be clearly visible.

       (2) Barriers around works must be:

(a) all red; or

(b) all orange; or

(c) red and white, or orange and white, but with sufficient white to ensure contrast.

       (3) Works limit markers must not have weight, size, shape, colour, texture or material characteristics which may make them a hazard to aircraft operations.

Note   For example, works limit markers which are too light in weight, or which are too aerodynamically shaped, may become airborne in strong winds and strike aircraft.

       (4) Works limit markers must be spaced at intervals that ensure they are clearly visible to works personnel, including works personnel using works equipment or vehicles.

       (5) When used on a movement area, works limit markers must:

(a) be placed inside the barriers around the works and behind unserviceability markings; and

(b) not be used to convey information to pilots about
