Title 14 - Aeronautics and Space
This part: (a) Establishes standards for determining obstructions in navigable airspace; (b) Sets forth the requirements for notice to the Administrator of certain proposed construction or alteration; (c) Provides for aeronautical studies of obstructions to air navigation, to determine their effect on the safe and efficient use of airspace; (d) Provides for public hearings on the hazardous effect of proposed construction or alteration on air navigation; and (e) Provides for establishing antenna farm areas. For the purpose of this part: Airport available for public use means an airport that is open to the general public with or without a prior request to use the airport. A seaplane base is considered to be an airport only if its sea lanes are outlined by visual markers. Nonprecision instrument runway means 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, and for which no precision approach facilities are planned, or indicated on an FAA planning document or military service military airport planning document. Precision instrument runway means 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 by an FAA approved airport layout plan; a military service approved military airport layout plan; any other FAA planning document, or military service military airport planning document. Utility runway means 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 means 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 airport layout plan, a military service approved military airport layout plan, or by any planning document submitted to the FAA by competent authority.

(b) The standards used by the Administrator in the establishment of flight procedures and aircraft operational limitations are not set forth in this part but are contained in other publications of the Administrator. [Doc. No. 1882, 30 FR 1839, Feb. 10, 1965, as amended by Amdt. 77–9, 36 FR 5970, Apr. 1, 1971] This part applies to: (a) Any object of natural growth, terrain, or permanent or temporary construction or alteration, including equipment or materials used therein, and apparatus of a permanent or temporary character; and (b) Alteration of any permanent or temporary existing structure by a change in its height (including appurtenances), or lateral dimensions, including equipment or materials used therein.
