(A) In order to carry out the provisions of this section, there are hereby created and established certain airport zones which include all of the land lying beneath the approach surfaces, transitional surfaces, horizontal surfaces, and conical surfaces as they apply to Harnett County Airport. Such zones are shown on the “Harnett County Airport Height Control Map”.
(B) An area located in more than one of the following airport zones is considered to be only in the airport zone with the more restrictive height limitation.
(C) The various zones are established and defined as follows:
(1) Nonprecision instrument approach zone (for runway larger than utility with a visibility minimum greater than three-fourths of a mile). The inner edge of this approach zone coincides with the width of the primary surface and is 500 feet wide. The approach zone expands outward uniformly to a width of 3,500 feet at a horizontal distance of 10,000 feet from the primary surface. 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 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. The horizontal zone does not include the approach and transitional zones.
(4) Conical zone. The conical zone is established as the area that commences at the periphery of the horizontal zone and extends outward and upward there from form a horizontal distance of 4,000 feet.
