9Foos 15 rnt 610 map, the datum s 11 be mean sea level elevation unless otherwise specified. 9. HELIPORT PRIMARY SURFACE - The area of the primary surface coincides in size and shape with the designated takeoff and landing area of a heliport. This surface is a horizontal plane at the elevation of the established heliport elevation. 10. HORIZONTAL SURFACE - The horizontal surface is established by swinging arcs of 10,000 feet radii from the center of each end of the primary surface of each runway, and connecting the adjacent arcs by drawing lines tangent to those arcs. The horizontal surface does not include the approach and transitional surfaces. The elevation of the horizontal surface represents a plane 150 feet above the established airport elevation. 11. 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. 12. NONCONFORMING USE - Any pre-existing structure, object of natural growth, or use of land which is inconsistent with the provisions of this ordinance or an amendment thereto. 13. NONPRECISION INSTRUMENT RUNWAY - A runway having an existing instrument approach procedure utilizing air navigation facilities with only horizontal guidance, or area type navigation equipment, for which a straight-in nonprecision approach procedure has been approved or planned. 14. OBSTRUCTION - Any structure, growth, or other object, including a mobile object, which exceeds a limiting height set forth in Section IV of this ordinance. 15. PERSON - An individual, firm, partnership, corporation, company, association, joint stock association, or governmental entity; includes a trustee, a receiver, an assignee, or a similar representative of any of then. 16. PRECISION INSTRUMENT RUNWAY - A 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 air- port layout plan or any other planning document. 17. PRIMARY, APPROACH, TRANSITIONAL, HORIZONTAL, AND CONICAL SURFACE ZONES - These zones are set forth in Section III of this Ordinance. 18. PRIMARY SURFACE - A surface longitudinally centered on a runway. The width of the primary surface is 1,000 feet and the length extends 200 feet beyond each end of the runway. The elevation of the primary surface is the same as the elevation of the nearest point on the runway centerline. 0-1.6 -3-
