The approach surfaces, as shown on the zoning plan, are described as follows:
(a) an imaginary inclined surface abutting the end of the strip surface associated with runway approach 17 and ascending, from an assigned elevation of 52.95 m above sea level, at a ratio of 1 m measured vertically to 20 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centre line of the strip surface and distant 2 500 m measured horizontally from the end of the strip surface; the outer ends of the imaginary horizontal line being 280 m from the projected centre line and 125 m above the assigned elevation at the end of the strip surface associated with runway approach 17; and
(b) an imaginary inclined surface abutting the end of the strip surface associated with runway approach 35 and ascending, from an assigned elevation of 43.52 m above sea level, at a ratio of 1 m measured vertically to 20 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centre line of the strip surface and distant 2 500 m measured horizontally from the end of the strip surface; the outer ends of the imaginary horizontal line being 280 m from the projected centre line and 125 m above the assigned elevation at the end of the strip surface associated with runway approach 35.
