for which lighting is provided.

       (4) For Table 7.16 (1), the superscript letters against certain dimensions have the following meaning:

           * a means that the take-off climb starts from the end of the clearway, if a clearway is provided;

           * b means that the final runway width may be reduced to 1 200 m — but only if the runway is used only by aircraft with take-off procedures which do not include changes of heading greater than 15 degrees for operations conducted in IMC or at night.

7.17 Establishment of the OLS

       (1) The following OLS must be established for a non-instrument runway and a non-precision instrument runway:

(a) the conical surface;

(b) the inner horizontal surface;

(c) the approach surface;

(d) the transitional surface;

(e) the take-off climb surface.

       (2) The following OLS must be established for a precision approach runway:

(a) the outer horizontal surface;

(b) the conical surface;

(c) the inner horizontal surface;

(d) the approach surface;

(e) the inner approach surface;

(f) the transitional surface;

(g) the inner transitional surface;

(h) the baulked landing surface;

(i) the take-off climb surface.

       (3) Where 2 OLS overlap, the lower surface must be used as the controlling obstacle limitation surface.

7.18 Procedures for aerodrome operators to deal with obstacles in the OLS

       (1) An aerodrome operator must:

(a) monitor the OLS for the aerodrome; and

(b) report to CASA, in writing, any infringement, or potential infringement, of the OLS.

       (2) When a new obstacle is identified, the aerodrome operator must ensure that pilots are informed of it by NOTAM.

       (3) For subsection (2), unless otherwise stated in the data product specification (DPS) for the aerodrome, the information must include the following:

(a) the nature of the obstacle;

       Note   For example, whether the obstacle is a structure or machinery or of another kind.

(b) the distance and bearing of the obstacle from:

           (i) if the obstacle is within the take-off area — the start of the take-off end of 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
