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 02 and ascending, from an assigned elevation of 62.43 m above sea level, at a ratio of 1 m measured vertically to 40 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centre line of the strip surface and distant 3 000 m measured horizontally from the end of the strip surface; the outer ends of the imaginary horizontal line being 525 m from the projected centre line and 75 m above the assigned elevation at the end of the strip surface associated with runway approach 02; and
(b) an imaginary inclined surface abutting the end of the strip surface associated with runway approach 20 and ascending, from an assigned elevation of 58.32 m above sea level, at a ratio of 1 m measured vertically to 40 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centre line of the strip surface and distant 3 000 m measured horizontally from the end of the strip surface; the outer ends of the imaginary horizontal line being 525 m from the projected centre line and 75 m above the assigned elevation at the end of the strip surface associated with runway approach 20.
