fitting must be located evenly around the object or structure, at not more than 120 degrees from any adjacent floodlight fitting; and

(b) at each location:

 (i) there must be at least 2 floodlight fittings; and

 (ii) each fitting must be on a separate circuit and capable of continuing to operate following the malfunction of another light.

9.36 Serviceability of obstacle lights

       (1) For obstacle lights located within the OLS of an aerodrome, the aerodrome operator must establish an obstacle lights serviceability monitoring program that includes the following elements:

(a) for aerodromes with scheduled international air transport operations during the hours of night — observation of the obstacle lights at least once in every 24 hour period, or such longer period as CASA approves in writing on the basis of the aerodrome operator's written safety assessment;

(b) for aerodromes with scheduled domestic air transport operations during the hours of night — observation of the obstacle lights at least once in every 48 hour period, or such longer period as CASA approves in writing on the basis of the aerodrome operator's written safety assessment;

(c) for aerodromes other than those mentioned in paragraphs (a) and (b) — observation of the obstacle lights at least once in every 7 day period;

(d) if a medium-intensity or high-intensity obstacle light is not readily observable for paragraph (a), (b) or (c):

           (i) a procedure to ensure that the light is monitored in accordance with the relevant monitoring period specified in paragraph (a), (b) or (c), or such longer period as CASA approves in writing on the basis of the aerodrome operator's written safety assessment; or

           (ii) at an aerodrome occupied by aerodrome personnel — the installation of an automatic light-failure indicator to be monitored by the personnel.
       (2) For a hazardous obstacle located within the OLS of the aerodrome, if there is an obstacle light outage then the aerodrome operator must:

(a) immediately request the NOTAM Office to advise pilots of the details of the outage; and

(b) as soon as possible, liaise with the owner of the obstacle light so that the outage is repaired as quickly as possible; and

(c) if the obstacle light is determined by CASA, in writing, as essential for aviation safety:

           (i) immediately report the outage to any aircraft that are manoeuvring, or are about to manoeuvre, on an affected runway; and

           (ii) immediately close the runway or close the aerodrome, as the case requires, until the outage is repaired; and

           (iii) notify CASA as soon as possible of the outage.

       Note   For CASA determining that an obstacle light is essential for aviation safety, see subsection 7.19 (1).

       (3) The aerodrome operator's aerodrome manual must include the following:
