§ 25-3. Airport zones; established and defined.

In order to carry out the provisions of this article, there are hereby created and established certain zones which includes all of the land lying beneath the approach surfaces, transitional surfaces, horizontal surfaces, and conical surfaces as they apply to the Miles City Airport. Such zones are shown on the FAR Part 77 Airspace Drawing of the current Miles City Airport Plan drawing set, which is attached to this article and made a part hereof. An area located in more than one of the following zones is considered to be only in the zone with the more restrictive heights limitation. The various zones are hereby established and defined as follows:

(1)

Approach surface zone. The inner edge of this approach zone coincides with the width of the primary surface. The approach zone expands outward uniformly to a width as shown on the FAR Part 77 Airspace Drawing of the current Miles City Airport Plan drawing set. Its centerline is the continuation of the centerline of the runway.

(2)

Transitional zones. The transitional zones are the areas beneath the transitional surfaces.

(3)

Horizontal zone. The horizontal zone is established by swinging arcs of 10,000 feet radii from the center of each end of the primary surface of each runway and connecting the adjacent arcs by drawing lines tangent to those arcs.

(4)

Conical zone. The conical zone is established as the area that commences at the periphery of the horizontal zone and extends outward therefrom a horizontal distance of 4,000 feet.
