           (ii) a minimum of 5 equally-spaced white markers, each with a base not less than 0.75 m in diameter; and

Note   See the illustration in Figure 8.103 (2).

(d) not more than 15 m from:

 (i) the wind direction indicator; or

 (ii) the additional wind direction indicator located closest to the apron of the aerodrome.

8.104 Ground signals in signal areas

       (1) This section applies only if a signal area is provided.

       (2) A "total unserviceability" signal must be displayed in a signal area when an aerodrome is closed to landing aircraft.

       (3) As shown in Figure 8.104 (3), a "total unserviceability" signal must consist of 2 white stripes, 0.9 m wide and 6 m long, bisecting each other at right angles.

       (4) A "restricted operations" signal must be displayed in a signal area at an aerodrome with more than 1 type of surface on its movement area, to indicate whether aircraft are only to use:

(a) the sealed runways, taxiways and aprons; or

(b) if there are no sealed runways — the gravel runways.

       (5) As shown in Figure 8.104 (5), a "restricted operations" signal must consist of 2 white circles, each 1.5 m in diameter, connected by a white crossbar 1.5 m long and 0.4 m wide.

CHAPTER 8

Division 9 Markings for unserviceable areas and works areas

8.105 Introduction

        This Division provides for:

(a) the markings for an unserviceable area of a runway, taxiway, apron or holding bay; and

(b) the markers for:

 (i) the boundary of an unserviceable area; and

 (ii) the limits of a works area.

8.106 Markings for unserviceable runways, taxiways and other movement areas

  General

       (1) Subject to sections 8.107 and 9.128, an unserviceability marking must be displayed on a runway or taxiway, or on that portion of a runway or taxiway, which is unserviceable.

Note   The unserviceability markings mentioned in this section are not to be confused with unserviceability markers mentioned in Table 8.07 (3)-1 and section 8.108.

       (2) An unserviceability marking must be:

(a) when displayed on a runway — white; and

(b) when displayed on a taxiway — yellow.

       (3) When a runway is covered in snow or other contaminant, a more conspicuous colour than white must be used for the unserviceability markings.

       (4) If a runway or a taxiway, or a portion of a runway or a taxiway, or any other part of the movement area, is unserviceable because it is permanently closed, all runway and taxiway markings must be obliterated except for those markings used in accordance with this section to indicate the unserviceability.
