The boundary of the outer limits of lands, shown on Cambridge Bay Airport Zoning Plan No. E.1756 dated September 9, 1983, is described as follows:
[...]
The approach surfaces, shown on Cambridge Bay Airport Zoning Plan No. E.1756 dated September 9, 1983, are surfaces abutting each end of the strip associated with the runway designated 13-31 and are described as inclined planes having a ratio of 1 m measured vertically to 50 m measured horizontally rising to imaginary horizontal lines drawn at right angles to the projected centre line of the strip 300 m measured vertically above the elevation at the ends of the strip and 15 000 m measured horizontally from the ends of the strip, the outer ends of the imaginary horizontal lines being 2 400 m from the projected centre line.
[...]
The outer surface, shown on Cambridge Bay Airport Zoning Plan No. E.1756 dated September 9, 1983, is an imaginary surface located at a common plane established at a constant elevation of 45 m above the assigned elevation of the airport reference point, except that where the common plane is less than 9 m above the surface of the ground, the imaginary surface is located at 9 m above the surface of the ground.

The strip associated with runway 13-31 as shown on Cambridge Bay Airport Zoning Plan No. E.1756 dated September 9, 1983, is 300 m in width, 150 m on each side of the centre line of the runway, and 1 948.8 m in length.
[...]
The transitional surfaces, shown on Cambridge Bay Airport Zoning Plan No. E.1756 dated September 9, 1983, are surfaces consisting of an inclined plane rising at a ratio of 1 m measured vertically to 7 m measured horizontally at right angles to the centre line and centre line produced of the strip and its approach surfaces to an intersection with the outer surface.
