The approach surfaces, shown on Campbell River Airport Zoning Plan No. (Z) B.C. 1594, sheets 1 to 13 inclusive, dated April 12, 1983, are surfaces abutting each end of the strip associated with the runway designated 11-29 and are described as follows:
-
(a) a surface abutting the end of the strip associated with runway approach 11 consisting of an inclined plane having a ratio of 1 m measured vertically to 50 m measured horizontally rising to an intersection with the outer surface, thence such approach surface shall be horizontal and contiguous to the said outer surface to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 3 000 m measured horizontally from the end of the strip, the outer ends of the imaginary horizontal line being 600 m from the projected centre line; and
-
(b) a surface abutting the end of the strip associated with runway approach 29 consisting of an inclined plane having a ratio of 1 m measured vertically to 40 m measured horizontally rising to an intersection with the outer surface, thence such approach surface shall be horizontal and contiguous to the said outer surface to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 3 000 m measured horizontally from the end of the strip, the outer ends of the imaginary horizontal line being 600 m from the projected centre line.
