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:
AIRPORT
The Reading Regional Airport, located within Bern Township,
Berks County, Pennsylvania.
APPROACH SURFACE
A 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 SURFACE
A 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 NAVIGATION
An obstruction determined to have a substantial adverse effect
on the safe and efficient utilization of navigable airspace.
HORIZONTAL SURFACE
A 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 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.
NON-PRECISION-INSTRUMENT RUNWAY
A 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.
OBSTRUCTION
Any structure, growth or other object, including a mobile
object, which exceeds a limiting height set forth in the Muhlenberg
Township Code.
PRECISION-INSTRUMENT RUNWAY
A 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 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 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.
RUNWAY
A defined area on an airport prepared for landing and takeoff
of aircraft along its length.
TRANSITIONAL SURFACE
Surfaces 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 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.
