The approach surfaces, shown on Wiarton Airport Zoning Plan No. 42-062 84-87, Sheets 2 to 8 inclusive and 10 to 13 inclusive, dated April 2, 1986 are surfaces abutting each end of the strips associated with runways designated 05-23 and 11-29 and are described as follows:
-
(a) a surface abutting the end of the strip associated with runway approach 05 consisting of an inclined plane having a ratio of 1 m measured vertically to 50 m measured horizontally, rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 15 000 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 2 400 m from the projected centre line; said imaginary horizontal line being 300 m above the elevation at the end of the strip;
-
(b) a surface abutting the end of the strip associated with runway approach 23 consisting of an inclined plane having a ratio of 1 m measured vertically to 50 m measured horizontally, rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 15 000 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 2 400 m from the projected centre line; said imaginary horizontal line being 300 m above the elevation at the end of the strip;
-
(c) 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 25 m measured horizontally, rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 1 075 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 137.5 m from the projected centre line; the said imaginary horizontal line being 43 m above the elevation at the end of the strip; and
-
(d) 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 25 m measured horizontally, rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 1 100 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 140 m from the projected centre line; said imaginary horizontal line being 44 m above the elevation at the end of the strip.
