Definitions for airport area protection standards. As used in this section, the following terms shall have the meanings indicated:
AIRPORTBraden Airpark, or its successor.
APPROACHTransitional, horizontal, and conical zones. These zones are set forth in this section.
APPROACH SURFACEA surface longitudinally centered on the extended runway center line, extending outward and upward from the end of the primary surface and at the same slope as the approach zone height limitation slope set forth in §
200-41D of this chapter. In plan, the perimeter of the approach surface coincides with the perimeter of the approach zone.
CONICAL SURFACEA surface extending outward and upward from the periphery of the horizontal surface at a slope of 20 to one for a horizontal distance of 4,000 feet.
HAZARD TO AIR NAVIGATIONAn obstruction determined to have a substantial adverse effect on the safe and efficient utilization of the navigable airspace.
HORIZONTAL SURFACEFor the purpose of determining the height limits in all zones set forth in this chapter and shown on the Zoning Map, the datum shall be mean sea level elevation unless otherwise specified.
HORIZONTAL SURFACEA horizontal plane 150 feet above the established airport elevation, the perimeter of which in plan coincides with the perimeter of the horizontal zone.
NONCONFORMING USEAny preexisting structure, object of natural growth, or use of land which is inconsistent with the provisions of this chapter or an amendment thereto.
OBSTRUCTIONAny structure, growth, or other object, including a mobile object, which exceeds a limiting height set forth in §
200-41D of this chapter.
PERSONAn individual, firm, partnership, corporation, company, association, joint stock association, or governmental entity; includes a trustee, a receiver, an assignee, or a similar representative of any of them.
PRIMARY SURFACEA surface longitudinally centered on a runway. When the runway has a specially prepared hard surface, the primary surface extends 200 feet beyond each end of that runway; when the runway has no specially prepared hard surface, or planned hard surface, the primary surface ends at each end of that runway. The width of the primary surface is set forth in §
200-41C of this chapter. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway center line.
RUNWAYA defined area on an airport prepared for landing and takeoff of aircraft along its length.
STRUCTUREAn object, including a mobile object, constructed or installed by man, including but without limitation, buildings, towers, cranes, smokestacks, earth formation, and overhead transmission lines.
TRANSITIONAL SURFACEThese surfaces extend outward at ninety-degree angles to the runway center line and the runway center lines extended at a slope of seven feet horizontally for each foot vertically from the sides of the primary and approach surfaces to where they intersect the horizontal and conical surfaces.
TREEAny object of natural growth.
UTILITY RUNWAYA runway that is constructed for and intended to be used by propeller-driven aircraft of 12,500 pounds maximum gross weight and less.
VISUAL RUNWAYA runway intended solely for the operation of aircraft using visual approach procedures.
