Federal Aviation Administration (FAA) Criteria

Federal Aviation Regulation Part 77, Objects Affecting Navigable Airspace, establishes standards and notification requirements for objects affecting navigable airspace. Examples of objects that may affect navigable airspace include buildings, communication towers, antenna structures, temporary construction cranes, etc.

  • Notification as required by Part 77 serves as the basis for:

  • Evaluating the effect of the construction or alteration on operating procedures

  • Determining the potential hazardous effect of the proposed construction on air navigation

  • Identifying mitigating measures to enhance safe air navigation

  • Charting of new objects

Notification allows the FAA to identify potential aeronautical hazards in advance, thus preventing or minimizing the adverse impacts to the safe and efficient use of navigable airspace. Notification, if required, is accomplished by completing and submitting an FAA Form 7460-1, Notice of Proposed Construction or Alteration. 

FAA Advisory Circular 70/7460-2K, Proposed Construction or Alteration of Objects that May Affect the Navigable Airspace, is a publication that provides information to persons proposing to erect or alter an object that may affect the navigable airspace. The publication explains and illustrates the requirement to notify the FAA before construction begins and the FAA's responsibility to respond to these notices in accordance with the requirements of Federal Aviation Regulation Part 77.


Denton Municipal Airport Overlay District

To prevent obstructions to safe aircraft navigation, the City of Denton regulates the maximum height of all structures within the Denton Municipal Airport Overlay District. It is the purpose and intent of this article to regulate and restrict the height of structures and objects of natural growth and the use of property near the Denton Enterprise Airport. The regulations are intended to prevent the encroachment of noise sensitive or otherwise incompatible land uses which may endanger the health, safety, and welfare of the owners, occupants, or users of the land to prevent the creation or establishment of obstructions that are a hazard to air navigation. The regulations also are intended to implement state and federal rules pertaining to the regulation of land uses near airports.

Temporary Obstructions in Vicinity of the Airport

The FAA requires an evaluation on temporary obstructions (e.g., cranes, drilling rigs, etc.) any time that they will exceed a 100:1 sloped surface from the nearest point of the nearest runway out to 20,000 feet or 200 feet AGL (above ground level) beyond.

The FAA requires that Form 7460-1 be submitted at least 30 days before or more either before the date the proposed construction is to begin, or the date an application for a construction permit is to be filed.

Prior to erecting any temporary obstruction within 5 nautical miles of Denton Enterprise Airport, ensure that you contact Airport Operations at (940) 349-7722 so that a Notice to Airman (NOTAM) can be issued.

FAA’s Notice Criteria Tool

It is easy to determine if you need to file a 7460-1 by visiting the FAA’s Notice Criteria Tool page. By entering some information about your proposed location and height, the Tool will provide instructions on whether you need to complete the 7460 or not.
