the runway; or

 (ii) the ARP;

(c) the height of the obstacle in relation to the aerodrome elevation;

(d) if it is a temporary obstacle — the time during which it is a temporary obstacle.

Note   If CASA declares an obstacle within the aerodrome boundary as being hazardous, it may result in an operational limitation on the aerodrome from aircraft operators, or a relevant safety direction from CASA under regulation 11.245 of CASR, unless the hazardous obstacle is removed.

7.19 Objects or structures that could become obstacles in the OLS

       (1) If a proposed object or structure is identified as likely to be an obstacle, details of the relevant proposal must be referred to CASA for CASA to determine, in writing:

(a) whether the object or structure will be a hazard to aircraft operations; and

(b) whether it requires an obstacle light that is essential for the safety of aircraft operations.

Note   See also paragraph 9.36 (2) (c).

       (2) A runway must not be made available for night use for the first time until:

(a) the aerodrome operator has informed CASA of obstacles within the OLS; and

(b) CASA has determined that the obstacles will not adversely affect the safety of night operations.

 Temporary and transient obstacles

       (3) A temporary or transient obstacle:

(a) in close proximity to an aerodrome; and

(b) that infringes the OLS;

        must be referred to CASA to determine whether the obstacle will be a hazard to aircraft operations.

Note   Transient obstacles would include, for example, road vehicles, rail carriages and ships.

 Fences or levee banks

       (4) A fence or levee bank that infringes the OLS must be treated as an obstacle.

       (5) For this section:

(a) referrals or information to CASA must be made by the aerodrome operator in writing; and

(b) determinations by CASA must be in writing.

7.20 Monitoring of obstacles associated with instrument runways

       (1) An aerodrome operator must monitor any object or structure that may infringe the aerodrome's OLS and PANS-OPS airspace associated with instrument approach procedures.

Note   Under regulation 173.110 of CASR, instrument approach procedure designers provide aerodrome operators with information and drawings of the area around the aerodrome, showing the designed approach paths, the circling areas and locations of critical obstacles taken into account in the design.

       (2) An aerodrome operator must:

(a) establish procedures to monitor:

 (i) the OLS; and

 (ii) such obstacles, associated with the aerodrome's terminal instrument flight procedures, as are determined by the instrument flight procedure designer to be critical obstacles; and

(b) include the procedures in the aerodrome manual.

       (3) The aerodrome operator must inform the designer of a terminal instrument flight procedure at the aerodrome of the following:

(a) any change in the
