The approach surfaces, shown on Muskoka Airport Zoning Plan No. 44-022-82-48, Sheets 2, 5, 6, 7, 8 and 9, dated August 24, 1983, are surfaces abutting each end of the strips associated with runways designated 09-27 and 18-36 and are described as follows:
-
(a) a surface abutting the end of the strip associated with runway approach 09 consisting of an inclined plane having a ratio of 1 m measured vertically to 40 m measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 2 500 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 310 m from the projected centre line; the said imaginary horizontal line being 62.50 m measured vertically above the elevation at the end of the strip;
-
(b) a surface abutting the end of the strip associated with runway approach 18 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 3 000 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 375 m from the projected centre line; the said imaginary horizontal line being 60 m measured vertically above the elevation at the end of the strip;
-
(c) a surface abutting the end of the strip associated with runway approach 27 consisting of an inclined plane having a ratio of 1 m measured vertically to 40 m measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 2 500 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 310 m from the projected centre line; the said imaginary horizontal line being 62.50 m measured vertically above the elevation at the end of the strip; and
-
(d) a surface abutting the end of the strip associated with runway approach 36 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 3 000 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 375 m from the projected centre line; the said imaginary horizontal line being 60 m measured vertically above the elevation at the end of the strip.
