   (B)   Airport height control definitions. For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
      AIRPORT. Herein, the Harnett Regional Jetport.
      AIRPORT ELEVATION. The highest point of an airport’s usable landing area measured in feet above sea level.
      APPROACH SURFACE. A surface longitudinally centered on the extended runway centerline, 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 § 153.192. In plan, the perimeter of the approach surface coincides with the perimeter of the approach zone.
      APPROACH, TRANSITIONAL, HORIZONTAL, AND CONICAL ZONES. These zones are set forth in § 153.191.
      CONICAL SURFACE. A surface extending outward and upward from the periphery of the horizontal surface at a slope of 20:1 for a horizontal distance of 4,000 feet.
      EXPECTED HEIGHT LIMITATIONS. Nothing in §§ 153.190 through 153.193 shall be construed as prohibiting the construction or maintenance of any structure, or growth of any tree or other vegetation to a height up to 50 feet above the surface of the land.
      HAZARD TO AIR NAVIGATION. An obstruction determined to have a substantial adverse effect on the safe and efficient utilization of the navigable airspace.
      HEIGHT. For the purpose of determining the height limits in all zones set forth in §§ 153.190 through 153.193 and shown on the zoning map, the datum shall be mean sea level elevation unless otherwise specified.
      HORIZONTAL SURFACE. A horizontal plane 150 feet above the established airport elevation, the perimeter of which in plan coincides with the perimeter of the horizontal zone.
      LARGER THAN UTILITY RUNWAY. A runway that is constructed for and intended to be used by propeller driven aircraft of greater than 12,500 pounds maximum gross weight and jet powered aircraft.
      NONPRECISION INSTRUMENT RUNWAY. A runway having an existing instrument approach procedure utilizing air navigation facilities with only horizontal guidance, or area type navigation equipment, for which a straight-in nonprecision instrument approach procedure has been approved or planned.
      OBSTRUCTION. Any structure, growth, or other object, including a mobile object, which exceeds a limiting height set forth in § 153.192.
      PRECISION INSTRUMENT RUNWAY. Runway having an existing instrument approach procedure utilizing an Instrument Land System (ILS) or a Precision Approach Radar (PAR).
      PRIMARY SURFACE. A 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. The width of the primary surface is set forth in § 153.191. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway centerline.
      RUNWAY. A defined area on an airport prepared for landing and take-off of aircraft along its length.
      RUNWAY ENDS. Refers to the existing physical end of the hard-surfaced asphalt runway on the southwest end (coordinates Lat. 35022'29.7" N, Long. 78044'16.5" W), and the future end of the runway on the northeast end after an extension to 5,000 feet (coordinates Lat. 35023'07.5" N, Long. 78043'36.4" W).
      STRUCTURE. In reference to §§ 153.190 through 153.193, structure shall mean an object, including a mobile object, constructed or installed by humans, including but without limitation, buildings, towers, cranes, smokestacks, earth formation, and overhead transmission lines.
      TRANSITIONAL SURFACES. These surfaces extend outward at 90 degree angles to the runway centerline and the runway centerline 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. TRANSITIONAL SURFACES for those portions of the precision approach surfaces, 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 surface and at 90-degree angles to the extended runway centerline.
      TREE. In reference to §§ 153.190 through 153.193, any object of natural growth.
      UTILITY RUNWAY. A runway that is constructed for and intended to be used by propeller driven aircraft of 12,500 pounds maximum gross weight and less.
      VISUAL RUNWAY. A runway intended solely for the operation of aircraft using visual approach procedures.
