The airport reference point, shown on Public Works Canada Deer Lake Airport Zoning Plans S-441-3, S-441-4, S-441-5 and S-441-6, dated November 30, 1984, is determined by measuring 975.36 m southwesterly along the centre line and centre line produced of runway 07-25 from the 07 end of the strip and thence measuring northwesterly at right angles 152.40 m from the centre line of the said runway 07-25.
[...]
The approach surfaces, shown on Public Works Canada Deer Lake Airport Zoning Plans S-441-1 to S-441-8 inclusive, dated November 30, 1984, are surfaces abutting each end of the strip associated with the runway designated 07-25 and are described as follows:
[...]
The outer surface, shown on Public Works Canada Deer Lake Airport Zoning Plans S-441-3, S-441-4, S-441-5 and S-441-6, dated November 30, 1984, 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 that 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 07-25, as shown on Public Works Canada Deer Lake Airport Zoning Plans S-441-3, S-441-4, S-441-5 and S-441-6, dated November 30, 1984, is 300 m in width, 150 m on each side of the centre line of the runway, and 1 948.8 m in length.
[...]
Each transitional surface, shown on Public Works Canada Deer Lake Airport Zoning Plans S-441-3, S-441-4, S-441-5 and S-441-6, dated November 30, 1984, is a surface 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 extending upward and outward from the lateral limits of the strip and its approach surfaces to an intersection with the outer surface.
[...]
The boundary of the outer limits of lands, shown on Public Works Canada Deer Lake Airport Zoning Plans S-441-3, S-441-4, S-441-5 and S-441-6, dated November 30, 1984, is a circular area having a radius of 4 000 m from the airport reference point.
