The following zones are established within the Air Space Control Area District. These zones are shown on the Municipal Airport Zoning Map which is made a part of the Official Zoning Map.
(A) Precision Instrument Approach Zone. A Precision Instrument Approach Zone is established at each end of the precision instrument runways of the airport for precision instrument landings and take-offs. The precision instrument approach zones shall have a width of 1,000 feet at a distance of 200 feet beyond each end of the runways, widening thereafter uniformly to a width of 16,000 feet at a distance of 50,200 feet beyond each end of the runways, its centerline being the continuation of the centerline of the runways.
(B) Nonprecision Instrument Approach Zone. Nonprecision Instrument Approach Zones are established at each end of the nonprecision runways of the airport for nonprecision landings and take-offs. The nonprecision instrument approach zones shall have a width of 500 feet beginning at a distance of 200 feet beyond each end of the runways, widening thereafter uniformly to a width of 2,000 feet and 3,500 feet, respectively, at a distance of 5,200 feet and 10,200 feet, respectively, beyond each end of the runways, its centerline being the continuation of the centerline of the runways.
(C) Transition zones. Transition zones are hereby established adjacent to each runway and approach zone. Transition zones extend outward and upward, at right angles to the runway centerline and runway centerline extended and at a slope of 7 feet horizontally for each 1 foot vertically from the side of the primary zones and from the sides of the approach zones to a point where they intersect the horizontal zone. Transitional zones for those portions of the precision approach zone which project through and beyond the limits of the conical zone extend a distance of 5,000 feet measured horizontally from the edge of the approach zone and right angles to the runway centerline.
(D) Horizontal zone. A horizontal zone is hereby established as the area which is constructed by swinging arcs of 10,000 feet radii from each end of the precision instrument primary zone and the east end of the east-west nonprecision primary zone and connecting the adjacent arcs by lines tangent to those arcs.
(E) Conical zone. A conical zone is hereby established as the area that commences at the periphery of the horizontal zone and extends outward there from a distance of 4,000 feet. The conical zone does not include the instrument approach zones and transition zones.
(F) Primary zone. The primary zone is a surface longitudinally centered on a runway extending 200 feet beyond each end of that runway. The width of the primary surface is 500 feet for nonprecision runways and 1,000 feet for precision instrument runways.
