The approach surfaces, shown on Stratford Municipal Airport Zoning Plan No. 31-009 89-064, dated August 29, 1994, are planes abutting each end of the strips associated with runways 05-23 and 17-35 and are described as follows:
-
(a) an inclined plane abutting the end of the strip associated with the approach to runway 05 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 elevation at the end of the strip;
-
(b) an inclined plane abutting the end of the strip associated with the approach to runway 23 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 1 776 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 341.4 m from the projected centre line; said imaginary horizontal line being 44.4 m above the elevation at the end of the strip;
-
(c) an inclined plane abutting the end of the strip associated with the approach to runway 17 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; and
-
(d) an inclined plane abutting the end of the strip associated with the approach to runway 35 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 1 311 m measured horizontally from the end of the strip; the outer ends of the imaginary horizontal line being 176.1 m from the projected centre line; said imaginary horizontal line being 43.7 m above the elevation at the end of the strip.
