The airport reference point, as shown on the zoning plan, is the geometric centre of the runway thresholds, at grid coordinates 7 069 965.22 N, 521 899.94 E (latitude 63°45′23.67089″ N, longitude 68°33′22.01292″ W). It is located on the centre line of the strip surface at a distance of 1 371.43 m from the end of the strip surface associated with runway 17-35, and its assigned elevation is 21.24 m above sea level.
[...]
The approach surfaces, as shown on the zoning plan, are described as follows:
[...]
The outer surface, as shown on the zoning plan, is an imaginary surface situated at a constant elevation of 45.00 m above the airport reference point, but at 9.00 m above the ground when that elevation would place the outer surface at less than 9.00 m above the ground.
The limit of the outer surface is described as follows:
[...]
The strip surface, as shown on the zoning plan, is an imaginary rectangular surface described as follows:
the strip surface associated with runway 17-35 is 300.00 m in total width, being 150.00 m on either side of the centre line of the runway. The strip surface commences 60.00 m to the northwest of threshold 17 and ends 60.00 m to the southeast of threshold 35, having a total length of 2 742.86 m. The 17 end of the strip surface has an assigned elevation of 33.01 m and the 35 end of the strip surface has an assigned elevation of 21.24 m. The bearing of the centre line of runway 17-35 is S 44°50′23″ E. Threshold 17 is defined as the northwestern limit of the existing runway surface and intersects with the centre line of the runway at grid coordinates 7 070 894.76 N and 520 975.59 E. Threshold 35 is defined as the southeastern limit of the existing runway surface and intersects with the centre line of the runway at grid coordinates 7 069 035.68 N and 522 824.29 E.

Each transitional surface, as shown on the zoning plan, is an imaginary inclined surface ascending at a ratio of 1.00 m measured vertically to 7.00 m measured horizontally at right angles to the centre line and projected centre line of the strip surface, extending upward and outward from the lateral limits of the strip surface and its approach surfaces to the intersection with the outer surface, whose description is limited, for the purposes of this Part, to the first paragraph of Part 3.

The limit of the area containing the lands to which these Regulations apply, as shown on the zoning plan, is generally defined by the limit of the area covered by the approach surfaces, outer surface, strip surfaces and transitional surfaces, and is more particularly described as follows:
