Airport: The Show Low Municipal Airport.

Airport elevation: The highest point of an airport’s usable landing area measured in feet from sea level.

Airport hazard: Any structure or object of natural growth located on or in the vicinity of a public airport, or any use of land near such airport, which obstructs the airspace required for the flight of aircraft in landing or takeoff at such airport or is otherwise hazardous to such landings or takeoffs of aircraft.

Approach, transitional, horizontal, and conical zones: These zones apply to the area under the approach, transitional, horizontal, and conical surfaces defined in Advisory Circular 150/5300 4A.

Board of adjustment: A board consisting of five (5) members appointed by the City of Show Low common council as provided in Title 19.

Height: For the purpose of determining the height limits in all zones set forth in this chapter and shown on the zoning map, the datum shall be mean sea level elevation unless otherwise specified.

Heliport primary surface: The area of the primary surface coincides in size and shape with the designated landing and takeoff area of a heliport (runway). This surface is a horizontal plane at the elevation of the established heliport elevation.

Nonconforming use: Any preexisting structure, object of natural growth, or use of land which is inconsistent with the provisions of this chapter or an amendment thereto.

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 instrument approach procedure has been approved or planned, or indicated on an FAA planning document or military services’ military airport planning document.

Person: An individual, firm, partnership, corporation, company, association, joint stock association, or government entity (including the City of Show Low). It includes a trustee, receiver, assignee, or similar representative of any of them.

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 FAA approved airport plan; a military services’ approved military airport layout plan; any other FAA planning document; or military services’ military airport planning document.

Primary surface: A surface longitudinally centered on a runway. When the runway has a specially prepared hard surface, the primary surface extends two hundred (200) feet beyond each end of that runway, but when the runway has no specially prepared hard surface, the primary surface ends at each end of that runway. The width of the primary surface of a runway will be that width prescribed in Part 77 of the Federal Aviation Regulations (FAR) for the most precise approach existing or planned for either end of that runway. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway centerline.

Runway: A defined area on an airport prepared for landing and takeoff of aircraft along its length.

STOL primary surface: An imaginary plane, three hundred (300) feet wide, centered on the runway. Its length extends one hundred (100) feet beyond each runway end. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway centerline.

Structure: An object constructed or installed by man, including, but without limitation, buildings, towers, smokestacks, earth formations, and overhead transmission lines.

Trees: Any object of natural growth.

Utility runway: A runway that is constructed for and intended to be used by propeller-driven aircraft of twelve thousand five hundred (12,500) pounds maximum gross weight and less.

Visual runway: A runway intended solely for the operation of aircraft using visual approach procedures with no straight-in instrument approach procedure and no instrument designation indicated on an FAA approved layout plan, or by any planning document submitted to the FAA by competent authority.
