The approach surfaces, shown on Public Works Canada La Ronge Airport Zoning Plan No. E.1882 dated July 5, 1985, are surfaces abutting each end of the strip associated with the runways designated 17-35 and 10-28 and are described as follows:
-
(a) a surface abutting the end of the strip associated with runway approach 35, consisting of an inclined plane having a ratio of 1 m measured vertically to 60 m measured horizontally, rising to an intersection with the outer surface, thence said approach surface shall slope upward at 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 291.5 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 17, consisting of an inclined plane having a ratio of 1 m measured vertically to 60 m measured horizontally, rising to an intersection with the outer surface, thence said approach surface shall slope upward at 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 292.3 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 10, 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 280.5 m from the projected centre line; said imaginary horizontal line being 62.5 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 28, 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 280.5 m from the projected centre line; said imaginary horizontal line being 62.5 m measured vertically above the elevation at the end of the strip.
