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:
[...]
The outer surface, shown on Grand Manan Airport Zoning Plan Nos. S-2503-1 to S-2503-6 inclusive, dated February 28, 1990, is an imaginary plane established at a constant elevation of 45 m above the elevation of the airport reference point, except that, where that plane is less than 9 m above the surface of the ground, the outer surface is located at 9 m above the surface of the ground.

Each transitional surface, shown on Grand Manan Airport Zoning Plan Nos. S-2503-1, S-2503-2 and S-2503-3, dated February 28, 1990, is 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 projected centre line 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 or to a plane established at an elevation of 113 m above sea level.
[...]
The outer boundary of the lands to which these Regulations apply, shown on Grand Manan Airport Zoning Plan Nos. S-2503-1 to S-2503-6 inclusive, dated February 28, 1990, is a semi-circle with a radius of 4 000 m centred on the airport reference point.
