The approach surfaces, shown on Grand Manan Airport Zoning Plan Nos. S-2503-1, S-2503-2 and S-2503-3, dated February 28, 1990, are planes abutting each end of the strip associated with runway 06-24 and are described as follows:
-
(a) an inclined plane abutting the end of the strip associated with runway approach 06 having a ratio of 1 m measured vertically to 30 m measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 1 200 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 165 m from the projected centre line; said imaginary horizontal line being 40 m above the elevation at the end of the strip; and
-
(b) an inclined plane abutting the end of the strip associated with runway approach 24 having a ratio of 1 m measured vertically to 30 m measured horizontally rising to an imaginary horizontal line drawn at right angles to the projected centre line of the strip and distant 1 350 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 180 m from the projected centre line; said imaginary horizontal line being 45 m above the elevation at the end of the strip.
