Kimmirut Airport Zoning Regulations (SOR/2012-96)

In this schedule, all grid coordinates are in metres (m) and refer to the 1983 North American Datum, Zone 19, Universal Transverse Mercator (UTM) projection. Grid coordinates have been computed using a combined average scale factor of 0.9996102.

In this schedule, all elevation values are in metres (m) and are based on the Canadian Geodetic Vertical Datum (CGVD28).

PART 1Airport Reference Point

The airport reference point, as shown on the zoning plan, is the geometric centre of the runway thresholds, at grid coordinates 6 968 964.095 N, 455 341.745 E (latitude 62°50′53″ N, longitude 69°52′38″ W). It is located on the centre line of the strip surface at a distance of 321.06 m from the end of the strip surface associated with runway 17-35, and its assigned elevation is 44.37 m above sea level.

PART 2Approach Surfaces

The approach surfaces, as shown on the zoning plan, are described as follows:

(a) an imaginary inclined surface abutting the end of the strip surface associated with runway approach 17 and ascending, from an assigned elevation of 52.95 m above sea level, at a ratio of 1 m measured vertically to 20 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centre line of the strip surface and distant 2 500 m measured horizontally from the end of the strip surface; the outer ends of the imaginary horizontal line being 280 m from the projected centre line and 125 m above the assigned elevation at the end of the strip surface associated with runway approach 17; and

(b) an imaginary inclined surface abutting the end of the strip surface associated with runway approach 35 and ascending, from an assigned elevation of 43.52 m above sea level, at a ratio of 1 m measured vertically to 20 m measured horizontally, to an imaginary horizontal line drawn at right angles to the projected centre line of the strip surface and distant 2 500 m measured horizontally from the end of the strip surface; the outer ends of the imaginary horizontal line being 280 m from the projected centre line and 125 m above the assigned elevation at the end of the strip surface associated with runway approach 35.

The elevation of an approach surface at any point is equal to the elevation of the nearest point on the centre line of that approach surface. The elevation of an approach surface centre line is calculated from the elevation of the abutting end of the strip surface, and increases at the constant ratios set out in this Part.

PART 3Outer Surface

The outer surface, as shown on the zoning plan, is an imaginary surface extending outward from the airport reference point to a radius of 4 000 m. It is situated at a constant elevation of 45 m above the airport reference point, but at 9 m above the ground when that elevation would place the outer surface at less than 9 m above the ground.

PART 4Strip Surface

The elevation of a strip surface at any point is equal to the elevation of the nearest point on the centre line of that strip surface. The elevation of the strip surface centre line between the strip surface end and the closest strip surface threshold is equal to the elevation of the strip surface end. The strip surface centre line between the strip surface thresholds is divided into segments, each of which has a slope that increases or decreases at the constant ratio set out in Column 7 of the table to this Part. The elevation of any point along a segment is calculated using the data set out in that table.

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 60 m in total width, being 30 m on either side of the centre line of the runway. The strip surface commences 30 m to the northwest of threshold 17 and ends 30 m to the southeast of threshold 35, having a total length of 642.12 m. The 17 end of the strip surface has an assigned elevation of 52.95 m and the 35 end of the strip surface has an assigned elevation of 43.52 m. The azimuth of the centre line of runway 17-35 is S 51°15′00″ E. Threshold 17 has grid coordinates of 6 969 146.21 N and 455 114.84 E, and threshold 35 has grid coordinates of 6 968 781.98 N and 455 568.65 E.

PART 5Transitional Surfaces

Each transitional surface, as shown on the zoning plan, is an imaginary inclined surface ascending at a ratio of 1 m measured vertically to 5 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.

The elevation of a point on the lower edge of a transitional surface abutting a strip surface is equal to the elevation of the nearest point on the centre line of the abutting strip surface. The elevation of a point on the lower edge of a transitional surface abutting an approach surface is equal to the elevation of the nearest point on the centre line of the abutting approach surface.

PART 6Limit of Area Containing Lands to Which These Regulations Apply

The limit of the area containing the lands to which these Regulations apply is defined by a circle with a radius of 4 000 m centred on the airport reference point, as shown on the zoning plan.
