Montréal–Pierre Elliott Trudeau International Airport Zoning Regulations — (a)
The approach surfaces, as shown on the zoning plan, are described as follows: (a) an imaginary inclined surface abutting the 06R end of Strip Surface 06R-24L and ascending, from an assigned elevation of 29.91 m above sea level, at a ratio of 1 m measured vertically to 50 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centreline of Strip Surface 06R-24L and distant 6 000 m measured horizontally from the end of Strip Surface 06R-24L; the outer ends of the imaginary horizontal line being 1 050 m from that projected centreline and 120 m above the assigned elevation at the 06R end of Strip Surface 06R-24L; (b) an imaginary inclined surface abutting the 24L end of Strip Surface 06R-24L and ascending, from an assigned elevation of 36.09 m above sea level, at a ratio of 1 m measured vertically to 50 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centreline of Strip Surface 06R-24L and distant 6 000 m measured horizontally from the end of Strip Surface 06R-24L; the outer ends of the imaginary horizontal line being 1 050 m from that projected centreline and 120 m above the assigned elevation at the 24L end of Strip Surface 06R-24L; (c) an imaginary inclined surface abutting the 06L end of Strip Surface 06L-24R and ascending, from an assigned elevation of 29.44 m above sea level, at a ratio of 1 m measured vertically to 50 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centreline of Strip Surface 06L-24R and distant 6 000 m measured horizontally from the end of Strip Surface 06L-24R; the outer ends of the imaginary horizontal line being 1 050 m from that projected centreline and 120 m above the assigned elevation at the 06L end of Strip Surface 06L-24R; (d) an imaginary inclined surface abutting the 24R end of Strip Surface 06L-24R and ascending, from an assigned elevation of 32.45 m above sea level, at a ratio of 1 m measured vertically to 50 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centreline of Strip Surface 06L-24R and distant 6 000 m measured horizontally from the end of Strip Surface 06L-24R; the outer ends of the imaginary horizontal line being 1 050 m from that projected centreline and 120 m above the assigned elevation at the 24R end of Strip Surface 06L-24R; (e) an imaginary inclined surface abutting the 10 end of Strip Surface 10-28 and ascending, from an assigned elevation of 29.28 m above sea level, at a ratio of 1 m measured vertically to 50 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centreline of Strip Surface 10-28 and distant 6 000 m measured horizontally from the end of Strip Surface 10-28; the outer ends of the imaginary horizontal line being 1 050 m from that projected centreline and 120 m above the assigned elevation at the 10 end of Strip Surface 10-28; and (f) an imaginary inclined surface abutting the 28 end of Strip Surface 10-28 and ascending, from an assigned elevation of 30.29 m above sea level, at a ratio of 1 m measured vertically to 50 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centreline of Strip Surface 10-28 and distant 6 000 m measured horizontally from the end of Strip Surface 10-28; the outer ends of the imaginary horizontal line being 1 050 m from that projected centreline and 120 m above the assigned elevation at the 28 end of Strip Surface 10-28.
