The approach surfaces, shown on North Battleford Airport Zoning Plan No. E.2745 dated November 30, 1989, are surfaces abutting each end of the strips associated with runways designated 06-24 and 12-30, and are described as follows:
-
(a) a surface abutting the end of the strip associated with runway approach 06 consisting of an inclined plane having a ratio of l m measured vertically to 20 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 m from the projected centre line; said imaginary horizontal line being 125 m above the elevation at the end of the strip;
-
(b) a surface abutting the end of the strip associated with runway approach 24 consisting of an inclined plane having a ratio of l m measured vertically to 20 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 m from the projected centre line; said imaginary horizontal line being 125 m above the elevation at the end of the strip;
-
(c) a surface abutting the end of the strip associated with runway approach 12 consisting of an inclined plane having a ratio of l 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 3 000 m measured horizontally from the strip; the outer ends of the imaginary horizontal line being 525 m from the projected centre line; said imaginary horizontal line being 75 m above the elevation at the end of the strip; and
-
(d) a surface abutting the end of the strip associated with runway approach 30 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 3 000 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 525 m from the projected centre line; said imaginary horizontal line being 75 m above the elevation at the end of the strip.
