Port), Air Carrier <br />A public airport served by a certified air carrier. This includes any runways, land areas or other facilities <br />designed or used for landing, taking off, processing passengers or cargo. <br />Airport, Commuter Service (Heliport: S.T.O.L.

This includes any runway, land area, or other facility <br />designed or used for the landing and taking off of small aircraft. <br /> <br />Airport – General Aviation <br />A public airport providing service to air passengers and/or leased aircraft for commercial and/or <br />institutional purposes. Development shall include, but not be limited to, runways, landing areas, <br />supporting infrastructure and facilities, Airport Surface Zones, and ancillary non-residential land uses. <br /> <br />Airport – Nonprecision Instrument Runway <br />A runway having an instrument approach procedure utilizing air navigation facilities with only horizontal <br />guidance, or area type navigation equipment, for which a straight-in nonprecision instrument approach <br />procedure has been approved or planned. <br /> <br />Airport –Precision Instrument Runway <br />A runway having an instrument approach procedure utilizing an Instrument Landing System (ILS) or a <br />Precision Approach Radar (PAR) or a facility for which a precision approach system has been approved <br />of planned. <br /> <br />Airport – Private Airfield <br />A private airfield or strip providing service for personal aircraft. Development shall include, but not be <br />limited to, runways, landing areas, Airport Surface Zones, supporting infrastructure and facilities. <br /> <br />Airport Runway <br />Edges of pavement for the taxiing, takeoff, and landing of aircraft. <br /> <br />Airport Surface Zones <br />Imaginary surfaces and zones that exist primarily to prevent existing or proposed manmade objects, <br />objects of natural growth, or terrain from extending upward into navigable airspace including: <br />(A) Approach Surface Zone. A surface longitudinally centered on the extended runway <br />centerline, extending outward and upward from the end of the primary surface and at the <br />same slope as the approach zone height limitation slope. The inner edge approach zone <br />coincides with the width of the primary surface and begins 200 feet from the runway end <br />and is 1,000 feet wide. The approach zone expands outward uniformly to a width of <br />16,000 feet at a horizontal distance of 50,000 feet from the primary surface. Its centerline <br />is the continuation of the centerline of the runway. <br />(B) Conical Surface Zone. A surface extending outward and upward from the periphery of the <br />horizontal surface at a slope of 20:1 for a horizontal distance of 4,000 feet. The conical <br />zone is established on the area that commences at the periphery of the horizontal zone <br />and extends outward there for a distance of 4,000 feet and upward at a slope of 20:1. <br />(C) Transitional Surfaces Zone. These surfaces extend outward at right angles (ninety <br />degree angles) to the runway centerline and extend at a slope of 7 feet horizontally for <br />each foot vertically from the sides of the primary and approach surfaces to where they <br /> 68
