For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
Airport. The Pitt-Greenville Airport located in the northwestern section of the city limits contiguous to the Tar River and U.S. 13-NC 11.
Airport elevation. The highest point of the airport’s landing surfaces measured in feet above mean sea level, i.e., 27.0 feet for Pitt-Greenville Airport.
Airport hazard. Any object violating the Federal Aviation Regulations (FAR) 14 C.F.R. Part 77, navigable airspace depicted on the airport hazard zoning map.
Airport reference point (ARP). The geometric center of the active runway configuration. For Pitt-Greenville Airport the ARP is latitude 35 degrees 38 minutes 03.73 seconds North, and longitude 77 degrees 07.73 minutes 00 seconds West.
Airport zone. An area that begins at the end of the primary surface for each active runway and extends outward and upward for the distance and angle specified in the Federal Aviation Regulations (FAR) Part 77 and depicted on the airport hazard zoning map.
Conical surfaces. An area extended outwardly from the inner horizontal surface an additional 4,000 feet and upward at a slope of 20:1. Therefore, the conical surface extends from 177.0 feet above mean sea level to 377.0 feet above mean sea level as depicted on the Airport Hazard Zoning Map.
Inner horizontal surface. A horizontal plane 150 feet above the airport elevation, i.e., 177.0 feet for Pitt-Greenville Airport. The horizontal surface is inscribed within 10,000 feet radii arcs from the ends of the primary surfaces as depicted on the Airport Hazard Zoning Map.
Nonconforming use. Any man-made structure, or object of natural growth or use of land or activity that is inconsistent with the provisions of this chapter or any amendment thereto.
Primary surface. A plane of varying elevation 1,000 feet wide for the precision approach runway and 500 feet wide for the non-precision approach and visual runways, centered on the respective runways and extending 200 feet beyond each runway end. The elevation of any point on the primary surface is equal to the runway elevation at that station measured along the runway centerline. The elevation of any point on the primary surface 200 feet beyond each runway end is equal to the centerline elevation of the runway end.
Runway. For Pitt-Greenville Airport there are three active runways, all constructed of asphaltic concrete and identified as follows:
Runway 2-20 - 6,500 feet × 150 feet Precision Approach
Runway 8-26 - 4,997 feet × 150 feet Non-Precision Approach
Runway 15-33 - 2,500 feet × 150 feet Visual Approach
Runway, non-precision. A runway having an existing or planned instrument approach procedure which provides for approaches at a decision height (DH) and visibility minimums greater than as defined for a precision approach.
Runway, precision. A runway having an existing or planned instrument approach procedure utilizing an instrument landing system (ILS) or precision approach radar (PAR) or global positioning system (GPS), which provides for approaches to a decision height (DH) of not less than 200 feet above ground level (AGL) with a visibility of not less than one-half mile or a runway visual range (RVR) of not less than 2,400 feet.
Runway, visual. A runway intended solely for aircraft operating under visual flight and approach procedures.
Transitional surfaces. An area extending upward from the sides of the primary surface for each active runway at a slope of 7:1 to the limit of the inner horizontal surface, and the area extending from the sides of precision approach zones outward 5,000 feet and upward at a slope of 7:1 (refer to airport hazard zoning map).
