The elevation of an approach surface at any point is equal to the elevation of the nearest point on the centre line of that approach surface. The elevation of an approach surface centre line is calculated from the assigned elevation of the abutting end of the strip surface and increases at the constant ratios set out in this Part.

The approach surfaces, as shown on sheets 1 to 27, 29 to 35 and 38 to 40 of the zoning plan, are surfaces abutting each end of the strip surfaces associated with runways 06-24 and 12-30. The approach surfaces are described as follows:

• (a) Approach Surface 06 is an imaginary inclined surface abutting the 06 end of Strip Surface 06-24 and ascending from an assigned elevation of 228.30 m, at a ratio of 1 m measured vertically to 60 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centre line of Strip Surface 06-24 and distant 3 000 m measured horizontally from the end of Strip Surface 06-24; thence ascending, at a ratio of 1 m measured vertically to 50 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centre line of Strip Surface 06-24, being the outer edge of the approach surface, and distant 9 000 m measured horizontally from the end of Strip Surface 06-24; the outer edge having a length of 1 500 m on either side of the projected centre line and an elevation 170 m above the assigned elevation of the 06 end of Strip Surface 06-24;

The elevation of a point on the lower edge of a transitional surface abutting a strip surface is equal to the elevation of the nearest point on the centre line of the abutting strip surface. The elevation of a point on the lower edge of a transitional surface abutting an approach surface is equal to the elevation of the nearest point on the centre line of the abutting approach surface.

Each transitional surface, as shown on sheets 16 to 18, 20 to 23, 27 and 28 of the zoning plan, is an imaginary inclined surface that extends upward and outward, from the lateral limits of the abutting strip surface and the abutting approach surface, at a ratio of 1 m measured vertically to 7 m measured horizontally and at right angles to the centre line of each abutting strip surface and approach surface to the intersection with the outer surface, or with another transitional surface.
