VISUAL RUNWAY - A runway intended solely for the operation of aircraft using visual approach procedures. SECTION III: AIRPORT ZONES In order to carry out the provisions of this Ordinance, there are hereby created and established certain zones which include all of the land lying within the approach zones, transitional zones, horizontal zones, and conical zones as they apply to a particular airport. Such zones are shown on the Sanford-Lee County Airport Hazard Map consisting of 1 sheet, prepared by Williams & Works and dated February 2, 1977, which is attached to this Ordinance and made a part hereof. An area located in more than one (1) of the following zones is considered to be only in the zone with the more restrictive height limitation. The various zones are hereby established and defined as follows: 1. Utilitv Runwav Nonprecision Instrument Approach Zone - The inner of this approach zone coincides with.the width of the primary surface and is five hundred (500) feet wide. The approach zone expands outward uniformly to a width of 2,000 feet at a hori- zontal distance 5,000 feet from the primary surface. Its centerline being the continuation of the centerline of the runway. 2. Transitional Zones - These zones are hereby established as the area beneath the transitional surfaces. These surfaces extend outward and upward at 90 degree angles to the runway centerline and the runway centerline extended at a slope of seven (7) feet horizontally for each foot vertically from the sides of the primary and approach surfaces to where they intersect the horizontal and conical surfaces. Transitional zones for those portions of the.precision approach zones which project through and beyond the limits of the conical surface, extend a distance of 5,000 feet measured horizontally from the edge of the approach zones and at 90 degree angles to the extended runway centerline. 3. Horizontal Zone swinging arcs of of the primary s adjacent arcs by horizontal zones zones. - The horizontal zone is hereby established by 5,000 feet radii from the center of each end zrface of each runway, and connecting the drawing lines tangent to those arcs. The does not include.the approach.and_transitional 4. Conical Zones - The conical zone is hereby established as the area that commences at the periphery of the horizontal zone and extends outward therefrom a horizontal distance of 4,000 feet. The conical zone.does not include the precision instru- ment approach zones and the transitional zones. -4-
