Definitions. For purposes of this section, the words listed in this subsection shall bear the respective meanings assigned to each. Words in the singular shall be used to include the plural, unless the context otherwise requires.
AIRCRAFTAny contrivance, except an unpowered hang glider or parachute, used for manned ascent into or flight through the air. See 74 Pa.C.S.A. § 5102.
AIRPORTRefers to the Zelienople Municipal Airport and is defined as any of land or any appurtenant areas which are used or intended to be used for airport buildings or air navigation facilities or rights-of-way, together with all airport buildings and facilities thereon. See 74 Pa.C.S.A. § 5102. As used herein, the term "airport" shall not include heliports. Private and public airports are defined separately in this section.
AIRPORT ELEVATIONThe highest point of an airport's usable landing area, measured in feet from sea level; here, 897.94 feet above mean sea level.
AIRPORT HAZARD AREAAny area of land or water upon which a hazard to air navigation (an airport hazard) might be established if not prevented as provided by these regulations and the Act of October 10, 1984, P.L. 837, No. 164.
APPROACH SURFACEA surface longitudinally centered on the extended runway center line, extending outward and upward from the end of the primary surface and at such slope as the approach surface zone height limitation slope set forth in Subsection
D of this section. In the 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.
DEPARTMENTThe Pennsylvania Department of Transportation.
FAAThe Federal Aviation Administration of the United States Department of Transportation.
HAZARD TO AIR NAVIGATIONAny object, natural or man-made, or use of land which obstructs the airspace required for flight or aircraft in landing or taking off at an airport or is otherwise hazardous as defined by "airport hazard" in 74 Pa.C.S.A. § 5102.
HEIGHTFor the purpose of determining the height limits in all zones set forth in this section and shown on the Zoning Map, the datum shall mean sea level elevation unless otherwise specified.
HEIGHT, TREEHeight as applied to trees shall mean the average of the expected height of the tree at maturity for the respective species in consideration of the geographic region and climate of the Borough.
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.
LARGER THAN UTILITY RUNWAYA 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.
NONCONFORMING USEAny preexisting structure, object of natural growth or use of land which is inconsistent with the provisions of this section or an amendment thereto.
NONPRECISION INSTRUMENT RUNWAYA runway having an existing instrument approach procedure utilizing air navigation facilities with only horizontal guidance or area-type navigation equipment and for which a straight-in nonprecision instrument approach procedure has been approved or planned.
OBSTRUCTIONAny structure, growth or other object, including a mobile object, which exceeds a limiting height set forth by this chapter.
PERSONAn individual, firm, partnership, corporation, company, association, joint-stock association or governmental entity, including a trustee, a receiver, an assignee or a similar representative of any of the above.
PRECISION INSTRUMENT RUNWAYA runway having an existing instrument approach procedure utilizing an Instrument Landing System (ILS) or a 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 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 for military runways or, when the runway has no specially prepared hard surface or planned hard surface, the primary surface is set forth in Subsection
C of this section. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway center line.
PRIVATE AIRPORTAn airport which is privately owned and which is not open or intended to be open to the public, as defined in 74 Pa.C.S.A. § 5102.
PUBLIC AIRPORTAn airport which is either publicly or privately owned and which is open to the public, as defined in 74 Pa.C.S.A. § 5102.
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, without limitation, buildings, towers, cranes, smokestacks, earth formation and overhead transmission lines.
TRANSITIONAL SURFACESThese surfaces extend outward at ninety-degree angles to the runway center line and the runway center line 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 ninety-degree angles to the extended runway center line.
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.
WOODLANDAn area of land, bearing a minimum of 1/4 acre, where the cumulative coverage of tree canopies at maturity covers 1/4 acre of land or one half of the ground on which the group of trees is located, whichever is greater.
