Certain words and phrases utilized under this §
355-38, as defined in the Aviation Code, shall have the meanings set forth therein. These words and phrases are defined as follows:
AIRPORTThe Reading Regional Airport, located within Bern Township, Berks County, Pennsylvania.
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 established within §
355-38 (Airport Overlay District). 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 navigable airspace.
HORIZONTAL SURFACEA horizontal plane 150 feet above the established airport elevation, the perimeter of which plane 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.
NON-PRECISION-INSTRUMENT RUNWAYA runway having an existing instrument and approach procedure utilizing air navigational facilities with only horizontal guidance or area-type navigational equipment for which a straight-in non-precision approach procedure has been approved or planned.
OBSTRUCTIONAny structure, growth or other object, including a mobile object, which exceeds a limiting height set forth in the Muhlenberg Township Code.
PRECISION-INSTRUMENT RUNWAYA runway having an existing instrument approach procedure utilizing an instrument landing system (ILS) or a precision approach radar (PAR). This shall also be construed as a runway for which a precision approach system is planned and is so indicated on an approved airport layout plan or 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 the runway. The width of the primary surface is set forth in this section of the Muhlenberg Township Code. The elevation of any point of 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.
TRANSITIONAL SURFACESurfaces extending 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 to a distance of 5,000 feet, as measured horizontally from the edge of the approach surface and at ninety-degree angles to the extended runway center line.
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.
