The approach surfaces, shown on Department of Public Works Bagotville Airport Zoning Plan No. MM-88-6775, dated January 4, 1988, are imaginary surfaces that abut each end of the strips associated with runways 18-36 and 11-29 and that are more particularly described as follows:
-

-
(b) a surface that abuts the end of the strip associated with runway 36 and consists 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 the approach surface slopes 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 at a distance of 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; the imaginary horizontal line being 294.6 m measured vertically above the elevation of the airport zoning reference point;
-
(c) a surface that abuts the end of the strip associated with runway 11 and consists 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 the approach surface slopes 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 at a distance of 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; the imaginary horizontal line being 293.4 m measured vertically above the elevation of the airport zoning reference point; and
-
(d) a surface that abuts the end of the strip associated with runway 31 and consists 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 the approach surface slopes 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 at a distance of 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; the imaginary horizontal line being 291 m measured vertically above the elevation of the airport zoning reference point.
