For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
AIRPORT. The Elizabeth City-Pasquotank County Regional Airport.
AIRPORT ELEVATION. Twelve feet above mean 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 § 158.28 of this chapter. 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 § 158.27 of this chapter.
CONICAL SURFACE. A surface extending outward and upward from the periphery of the horizontal surface at a slope of 20 to 1 for a horizontal distance of 4,000 feet.
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 this subchapter and shown on the city’s height restriction 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.
NON-CONFORMING USE. Any pre-existing structure, object of natural growth or use of land which is inconsistent with the provisions of this subchapter or any amendment thereto.
OBSTRUCTION. Any structure, growth or other object, including a mobile object, which exceeds a limiting height set forth in § 158.28 of this chapter.
PERSON. An 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 the aforesaid.
PRECISION INSTRUMENT RUNWAY. A runway having an existing instrument approach procedure utilizing an Instrument Landing System (ILS) or Precision Approach Radar (PAR). It also means a runway for which a precision approach system is planned and is so indicated on an approved airport layout plan or any other planning document.
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; for military runways or 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 § 158.27 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 centerline.
RUNWAY. A defined area of an airport prepared for landing and takeoff of aircraft along its length.
STRUCTURE. An object, including a mobile object, constructed or installed by humans, including by without limitation, buildings, towers, cranes, smokestacks, earth formation and overhead transmission lines.
TRANSITIONAL SURFACES. These surfaces extend outward at ninety-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. Any object of natural growth.
