vertical plane at right angles to the centreline of the runway.

       (4) The upper edge of the inner transitional surface must be located in the plane of the inner horizontal surface.

Note   For guidance only, see Figure 7.12 (1). CASA recommends that, subject to sections 6.55 and 6.56, the inner transitional surface should otherwise be used as the controlling surface for navigational aids, and aircraft and vehicle holding positions, which have to be located near the runway. The transitional surface should also be used as the controlling surface for building height control.

7.12 Baulked landing surface

Note   For guidance only, see Figure 7.12 (1).

       (1) The baulked landing surface must be an inclined plane originating at the relevant distance specified in Table 7.15 (1) after the threshold, and extending between the inner transitional surfaces.

       (2) The baulked landing surface must originate from an inner edge of the length specified in Table 7.15 (1) located horizontally and perpendicular to the centreline of the runway, with 2 sides from the ends of the inner edge diverging uniformly at the specified rate from the vertical plane containing the centreline of the runway, ending at an outer edge located in the plane of the inner horizontal surface.

       (3) The elevation of the inner edge must be equal to the elevation of the runway centreline at the location of the inner edge.

       (4) The specified slope of the baulked landing surface must be measured in the vertical plane containing the centreline of the runway.

7.13 Obstacle-free zone

        The obstacle-free zone must be kept free from the following:

(a) fixed objects or structures other than lightweight, frangibly-mounted navigation aids that must be located near the runway to perform their function;
(b) transient objects when the runway is being used for precision approaches.

Note   Transient objects include, for example, aircraft and vehicles.

7.14 Take-off climb surface

       (1) The take-off climb surface must be an inclined plane located beyond the end of the runway or clearway.

Note   For guidance, see Figure 7.14 (1).

       (2) The origin of the take-off climb surface must be the inner edge of the specified length, located at the specified distance from the end of the runway or the clearway.

       (3) The plane from the inner edge must slope upward at the specified rate, with the 2 sides of the plane originating from the ends of the inner edge concurrently diverging uniformly outwards to the final specified width, and continuing thereafter at that width for the remainder of the specified overall length of the take-off climb surface until it reaches the outer edge which is horizontal and perpendicular to the take-off
