§ 6-50. Definitions

The following words, terms and phrases, when used in this article, shall have the meanings ascribed to them in this section, except where the context clearly indicates a different meaning:

Airport means the Granite Shoals Airport.

Airport elevation means the established elevation of the highest point on the usable landing area measured in feet above sea level. The elevation of the airport is 860 feet MSL.

Airport hazard means any structure, tree or use of land which obstructs the air space required for the flight of aircraft or which obstructs or interferes with the control or tracking and/or data acquisition in the landing, taking off or flight at an airstrip, or at any installation or facility relating to flight, or tracking and/or data acquisition of the flight aircraft; hazardous, interfering with or obstructing such landing, taking off or flight of aircraft or which is hazardous to or interferes with tracking and/or data acquisition pertaining to flight of aircraft.

Airport hazard area means any area of land or water upon which an airport hazard might be established if not prevented as provided in this article.

Airport reference point means the point established as the approximate geographic center of the airport landing area and so designated.

Approach surface means a surface longitudinally centered on the extended runway centerline, extending outward and upward from the end of the runway primary surface and at the same slope as the approach zone height limitation slope set forth in section 6-52. In plan, the perimeter of the approach surface coincides with the perimeter of the approach zone.

Approach, transition and horizontal zones are set forth in section 6-51.

Displaced threshold means a changed runway boundary, altered because of technical or approach obstructions.

Hazard to air navigation means an obstruction determined to have a substantial adverse effect on the safe and efficient utilization of the navigable airspace.

Height means, for the purpose of determining the height limits in all zones set forth in this article and shown on the airspace boundaries map, the datum of mean sea level elevation unless otherwise specified.

Horizontal surface means a horizontal plane of 150 feet above the established runway elevation, the perimeter of which in plan coincides with the perimeter of the horizontal zone.

Nonconforming use means any pre-existing structure, object of natural growth, or use of land which is inconsistent with the provisions of this article or an amendment thereto.

Obstruction means any structure, growth, or other object, including a mobile object, which exceeds a limiting height set forth in section 6-52.

Person means an individual, firm, partnership, corporation, company, association, joint stock association, or body politic, and includes a trustee, receiver, assignee, administrator, executor, guardian or other representative.

Runway means the surface area of the airport used for the landing, takeoff or taxiing of aircraft.

Structure means an object, including a mobile object, constructed or installed by man, including but not limited to buildings, towers, cranes, smokestacks, earth formation and overhead transmission lines.

Transitional surfaces means those surfaces extending outward at 90-degree angles to the runway edges and the runway edges extended at a slope of seven feet horizontally for each one foot vertically from the sides of the approach surfaces to where they intersect the horizontal surface.

Tree means any plant having a woody stem or trunk.

Visual runway means a runway intended solely for the operation of aircraft using visual approach procedures.
