occurs to the relevant terrain profile or obstacles.

       (3) For an Aerodrome Terrain and Obstacle Chart – ICAO (Electronic), terrain data must be:

CHAPTER 7

Division 4 Principles of shielding

7.25 General

       (1) An aerodrome operator must inform CASA in writing of the presence of all obstacles at the aerodrome.

       (2) Subject to subsection (3), only CASA may determine whether or not a new obstacle is shielded by an existing obstacle.

       (3) An aerodrome operator may assess whether a new obstacle is shielded by an existing obstacle only if the assessment is made for publication in the operator's Type A chart.

       (4) A new obstacle is not to be considered as being shielded by an existing obstacle unless:

(a) CASA determines in writing that the new obstacle is shielded; or

(b) the aerodrome operator assesses, for publication in their Type A chart, that the new obstacle is shielded and the assessment has not been replaced by a CASA determination that the new obstacle is not shielded.

       (5) An aerodrome operator may apply in writing to CASA for a written determination on whether or not an obstacle is shielded.

Note   A new obstacle, located in the vicinity of an existing obstacle, and assessed as not being a hazard to aircraft, would be considered to be shielded. Only existing permanent obstacles may be considered in assessing the applicability of shielding of new obstacles.

       (2) Relevant standards under this Chapter are expressed in metric units.

8.02 Permanent aerodrome or partial movement area closure

        Unless a provision of this Chapter expressly provides otherwise, on a closed aerodrome or a closed part of the movement area of an aerodrome, all markings, markers, signals and signs (other than those indicating unserviceability) must be obscured or removed.

8.03 Colours

       (1) Colours used in aerodrome markings, markers, signals and signs must meet Australian Standard AS 2700-2011, Colour Standards for General Purposes, as in force or existing from time to time, in accordance with Table 8.03 (1).
