The imaginary surfaces defined in Title 14 CFR Part 77 include the primary surface, transitional surface,
approach surface, horizontal surface, and the conical surface. Exhibit 1J depicts a model example of
the application of the Part 77 surfaces.
Airport Noise Compatibility Planning – Title 14 CFR Part 150
Noise, by definition, is sound that is loud, unpleasant, unexpected, or undesired. The sound produced
by aircraft becomes noise when it disturbs people. The best way to minimize the adverse impact of
noise is to separate people from that noise. This set of federal regulations establishes the Yearly Day‐
Night Average Sound Level (DNL) as the metric for measuring noise impacts. DNL represents the aver‐
age noise received at a given location during the time measured.
Exhibit 1K lists land uses and the DNL level at which those uses are compatible. Below the 65 DNL lev‐
el, all land uses are normally compatible. Above the 65 DNL level, residences and places of public as‐
sembly are not compatible unless sound level reduction techniques are applied.
Airport Land Use Compatibility Planning – FAA Advisory Circular (AC) 150/5060‐6
This document guides the development of a compatibility plan to ensure the environs surrounding an
airport are not developed in a manner that could pose a risk to the airport’s operations. This document
specifically applies to land use and noise issues.
Airport Master Plans – FAA Advisory Circular (AC) 150/5070‐6A
This document guides the development of Airport Master Plans. The guiding principle of the airport
planning process is to develop a safe and efficient airport through the use of acceptable standards.
While there are many steps in the planning process, none of these steps should be treated in a piece‐
meal manner. The airside and landside issues must be equally evaluated to create a plan that provides
for compatible airport and community development where possible.
A Model Zoning Ordinance to Limit Height of Objects Around Airports – FAA Advisory Circular (AC)
150/5190‐4A
This advisory circular concerns itself with developing zoning ordinances to control the height of ob‐
jects. It is based upon the surfaces described in Subpart C of Title 14 CFR Part 77, Objects Affecting
Navigable Airspace. This document provides sample language and model ordinances for use by local
airports.
