and

(b) must finish where the upper edge is located in the plane of the inner horizontal surface.

Note   For guidance only, see Figure 7.08 (6)-1.

       (2) The transitional surface must slope upwards and outwards at a specified rate and be measured in a vertical plane at right angles to the centreline of the runway.

       (3) The elevation of a point on the lower edge of the transitional surface must be:

(a) along the side of the approach surface — equal to the elevation of the approach surface at the point; and

(b) along the side of the runway strip — equal to the elevation of the nearest point on the centreline of the runway or stopway.

7.10 Inner approach surface

        The inner approach surface:

(a) must be a rectangular portion of the approach surface immediately preceding the threshold; and

(b) must:

           (i) originate from an inner edge of the length relevantly specified in Table 7.15 (1), at the same location as the inner edge for the approach surface; and
           (ii) extend on 2 sides, parallel to the vertical plane containing the runway centreline, to an outer edge located at the distance specified in Table 7.15 (1) from, and parallel to, the inner edge.

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

7.11 Inner transitional surface

Note   For general guidance, the inner transitional surface is similar to the transitional surface but closer to a runway used for precision operations.

       (1) The lower edge of the inner transitional surface must originate from the end of the inner approach surface, extend down the sides of the inner approach surface to the inner edge of the inner approach surface, from there extend along the runway strip to the inner edge of the baulked landing surface, and from there extend up the side of the baulked landing surface to the point where the side of the baulked landing surface intersects the inner horizontal surface.

       (2) The elevation of a point on the lower edge of the inner transitional surface must be:

(a) along the side of the inner approach and baulked landing surfaces — equal to the elevation of the particular surface at that point; and
(b) along the runway strip — equal to the elevation of the nearest point on the centreline of the runway or stopway.

       (3) The inner transitional surface must slope upwards and outwards at the relevant rate specified in Table 7.15 (1), and is to be measured in a 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
